Melvor Idle Feature and Mechanics Research

Research date: 2026-06-03 Game: Melvor Idle Official website: https://melvoridle.com/ Official wiki: https://wiki.melvoridle.com/ Current wiki-reported version: v1.3.1, released 2024-10-30

This document is a source-grounded feature inventory and mechanics overview for Melvor Idle, an idle/incremental RPG inspired by RuneScape. It is based primarily on the official Melvor Idle wiki, with supporting checks of the official website and Steam store page.

The official wiki is community-run but identifies itself as the official wiki. The Beginner’s Guide notes that many raw data pages are imported directly from the game, while guides and explanatory pages are maintained by players and may lag behind current patches. This file treats raw data/official wiki structure as the strongest source, and flags possible uncertainty where the wiki itself marks pages as out of date or incomplete.

High-level game identity

Melvor Idle is a feature-rich idle/incremental RPG that compresses RuneScape-style skilling, combat, economy, loot, and completion goals into a mostly menu-driven idle game.

Core identity traits:

• Idle/incremental RPG with long-term offline and online progression.
• Inspired by RuneScape: skills, combat triangle, gear tiers, resource gathering, artisan processing, monsters, slayer, prayer, runes, skillcapes, completionism.
• Single-player progression with cloud saves, cross-platform access, and optional mods.
• Deep interlocking production chains: gather resources, process them, craft equipment/consumables, fight stronger monsters, unlock more systems.
• Runs as an idle game: most actions continue automatically until stopped, resources run out, the player dies, or a limit is reached.
• Strong completionist structure: skills, mastery, items, monsters, pets, capes of completion, expansion-specific completion.
• Current official wiki navigation reports 9 combat skills and 20 non-combat skills.
• Normal skills generally cap at level 120; skillcapes are available at level 99 and superior skillcapes at level 120. Into the Abyss introduces abyssal levels up to 60 for relevant skills.

Typical game loop

A practical Melvor loop is:

Start a save and choose game mode.

** Standard is the default experience. ** Hardcore adds permanent-death-style risk. ** Adventure changes the unlock economy and gates non-combat levels by combat level. ** Ancient Relics is an Atlas of Discovery mode built around dungeon-gated level caps and relics.

Pick an action from a skill page.

** Example: mine Copper Ore, chop Normal Logs, fish Raw Shrimp, or fight Chickens. ** The action runs repeatedly until the player stops it or the action cannot continue.

Gain skill XP and item-specific mastery XP.

** Skill XP raises the skill level and unlocks new actions/recipes/equipment. ** Mastery XP raises mastery level for the specific action/recipe/item.

Convert resources through production chains.

** Logs become Firemaking fuel, Fletching materials, Township/other inputs, or shop/economy resources. ** Fish become cooked food. ** Ores become bars, gear, runes, or other materials. ** Herbs become potions. ** Seeds become food, herbs, or trees through Farming.

Use products to push combat and unlock content.

** Food keeps the player alive. ** Gear improves combat stats. ** Runes power magic. ** Prayer points power prayers. ** Potions, summons, agility obstacles, astrology modifiers, pets, and shop upgrades increase efficiency or survivability.

Spend currencies on upgrades.

** GP buys bank slots, tools, Auto Eat, skill upgrades, materials, gloves, skillcapes, Township items, and more. ** Slayer Coins buy slayer gear, resupplies, and slayer-related upgrades. ** AP / Abyssal currencies support Into the Abyss systems. ** Museum Tokens support Atlas/Archaeology-related shop items.

Advance to harder monsters, dungeons, and expansion content.

** Combat areas and slayer areas provide monsters and drops. ** Dungeons and strongholds gate major gear and progression. ** Into the Mist / Impending Darkness / Into the Abyss style milestones unlock late-game or expansion systems.

Repeat for completion.

** Max every skill. ** 99 mastery every action. ** Find every item. ** Kill every monster. ** Unlock every pet. ** Earn base and expansion completion capes.

Thieving

Thieving pickpockets NPCs for GP and items.

Mechanics:

• Allotments produce food.
• Herbs feed Herblore.

Herblore

Herblore brews potions.

Mechanics:

• Uses herbs from Farming and other ingredients.
• Potions are divided broadly into combat and skill potions.
• Potions have charges; one charge is consumed per action even if the effect does not apply.
• Potions can be upgraded to higher tiers, generally up to tier IV, often using three lower-tier potions to make one higher-tier potion.
• Auto re-use can automatically activate a new potion when one runs out.

Agility

Agility builds an obstacle course that grants global active passives.

Mechanics:

• Obstacles provide bonuses and sometimes tradeoffs.
• Obstacles are built in slots/categories.
• TotH adds more obstacle tiers and an elite pillar.
• Into the Abyss adds a separate Abyssal obstacle course.
• Agility is a major optimization skill because its bonuses affect many unrelated systems.

Summoning

Summoning creates and uses familiars/tablets.

Mechanics:

• Discover marks.
• Create familiar tablets.
• Equip tablets for passive/action support.
• Unlock synergies by pairing familiars.
• Summoning XP can come from familiar use; in combat, familiars can attack and consume tablets.

• Township Tasks are static requests from the town: donate items, complete bounties, build buildings, or sometimes earn skill XP.
• Task rewards include Township XP/resources, GP, Slayer Coins, and other rewards.
• TotH’s stage 1 added Township for all players.
• Into the Abyss adds Abyssal Wave mechanics, buildings, biomes, resources, and rewards.

Alternative Magic

Alternative Magic is a non-combat method to train Magic.

Mechanics:

• It is still the Magic skill; XP is shared with Magic.
• Each Alt. Magic action takes 2 seconds.
• It can be trained offline.
• Uses runes and sometimes selected items.
• Produces resource conversion effects such as rune essence conversion, superheating bars, alchemy, and other utility spells.
• Benefits from rune preservation and some global item doubling/GP modifiers depending on the spell.

Cartography

Cartography is an Atlas of Discovery support skill.

Role:

• Explore the Map of Melvor.
• Reveal hidden areas and secrets.
• Locate dig sites for Archaeology.
• Uses ship/map progression, hex/grid exploration, travel costs/times, and survey mechanics.
• Has a maximum level of 120 even without Throne of the Herald.

Archaeology

Archaeology is an Atlas of Discovery gathering skill.

Role:

• Excavate dig sites located through Cartography.
• Discover artifacts, rare items, relic-style rewards, and items useful outside the skill.
• Uses tool upgrades such as brushes, sieves, shovels, and trowels.

Harvesting

Harvesting is an Into the Abyss non-combat skill.

Role:

• Exclusive to the Abyssal Realm and Into the Abyss content.
• Supports Abyssal resource gathering and progression.
• The wiki marks the Harvesting page as incomplete, so exact mechanics should be checked against current in-game UI or updated wiki pages for implementation-level details.

Idle and offline progression

Offline Progression is central to Melvor Idle.

Wiki-reported behavior:

• The game progresses while closed as if the player had stayed online, up to a maximum of 24 hours.
• The game records which skill/action was active when closed.
• On return, it simulates what would have happened during the offline period.
• Offline simulation includes XP, items, mastery XP, mastery level increases, summoning synergies, mastery tokens, and relevant effects.
• There is no functional difference between online and offline gains except that the player cannot switch actions while offline.
• Combat and Thieving require the relevant offline combat setting to be enabled because they can be dangerous.
• Farming does not auto-replant seeds offline.
• Equipped gloves, skillcapes, potions with Auto Re-use active, mastery benefits, and many passive modifiers work offline.

Design implications:

• Long-term planning matters more than constant clicking.
• Resource bottlenecks and action choice matter because the player commits to a single action while away.
• Offline combat requires risk calculation: HP, Auto Eat, food quantity, damage reduction, enemy max hit, and death penalty.

Mastery system

Mastery is a second progression layer tied to individual actions or recipes within non-combat skills.

Mechanics:

• Each action/recipe/item in a non-combat skill has its own mastery level, except Alt. Magic spells are handled differently.
• Completing an associated action gives mastery XP for that action.
• Higher mastery levels unlock item/action-specific bonuses.
• Each skill has a mastery pool.
• Mastery Pool checkpoints give skill-wide bonuses.
• Mastery Tokens can randomly drop while training non-combat skills and grant 0.1% of the corresponding skill’s maximum mastery pool XP when claimed.
• Mastery contributes to the Completion Log.
• Completion requires every skill action to reach mastery level 99.

Mastery creates a second reason to train low-level actions even after the skill level is high.

Bank and item management

The Bank is the player’s item storage and core management UI.

Features:

• Starts with 20 bank slots.
• Extra bank slots can be purchased from the Shop; price increases up to a cap.
• Bank Slot Tokens add slots without increasing shop slot price.
• Hardcore has a shop slot limit, but tokens and expansion slots can extend storage.
• Items can be sorted, manually moved, searched, and organized into tabs.
• Items can be locked to prevent accidental selling, bone burial, or container opening.
• Items can be sold for GP.
• Equipment and food can be equipped from the Bank.
• Mastery Tokens can be claimed from the Bank.
• Some items can be upgraded.
• New items are highlighted and appear in the first tab by default.

Bank capacity is itself a progression bottleneck and early GP sink.

Shop and upgrade economy

The Shop sells upgrades and items for multiple currencies.

Currencies mentioned by the Shop page:

• GP.
• AP / Abyssal Pieces.
• Slayer Coins.
• Abyssal Slayer Coins.
• Museum Tokens.

Shop categories include:

• General upgrades.
• Auto Eat.
• Skill upgrades.
• Axes, fishing rods, pickaxes and coatings.
• Cooking utilities: fires, furnaces, pots.
• Ship upgrades.
• Archaeology tools: brushes, sieves, shovels, trowels.
• Harvesters.
• God upgrades.
• Slayer and Abyssal Slayer items.
• Gloves.
• Skillcapes.
• Atlas of Discovery items.
• Into the Abyss items.
• Materials.
• Township items.

Important shop progression:

• Auto Eat is critical for idle combat.
• Tool upgrades speed up or improve gathering.
• Bank slots remove storage bottlenecks.
• Skill upgrades unlock efficiency and new mechanics.
• Skillcapes reward level 99; superior skillcapes reward level 120.

Combat mechanics

Combat is automatic once started.

Core loop:

Select a combat area, slayer area, dungeon, stronghold, or abyssal area.

Pick a monster or start a dungeon/encounter sequence.

Equip weapons, armour, food, prayers, potions, summons, and passives.

Combat proceeds automatically until the player dies, runs, or clears the target/dungeon.

Kills generate XP, bones, loot, slayer progress, and drops.

Use drops to upgrade gear or unlock harder content.

Combat stats

The Combat page lists key stats:

• Max Hit: maximum possible damage before damage reduction.
• Chance to Hit: chance an attack succeeds.
• Accuracy Rating: compared against enemy Evasion Rating.
• Damage Reduction (DR): percent reduction to incoming damage.
• Evasion Rating: chance to avoid attacks; separate melee, ranged, and magic evasion.
• Prayer Points: spent to maintain active prayers.
• Combat Level: approximation of power based on combat skills.

Combat triangle

Melvor uses a melee/ranged/magic combat triangle.

Standard relationships:

• Melee is strong against Ranged.
• Ranged is strong against Magic.
• Magic is strong against Melee.

Effects:

• Strong/weak matchups modify player damage and resistance/damage reduction.
• Standard mode has normal penalties.
• Hardcore, Adventure, and Ancient Relics use a harsher/reversed penalty model for weak combat styles.

Food and Auto Eat

Food is vital for combat and thieving.

Mechanics:

• Up to 3 types of food can be equipped.
• Food must be selected on the Combat or Thieving page to consume.
• Manual eating consumes selected food when clicked.
• Auto Eat is a shop upgrade that automatically consumes food when HP drops below a threshold.
• Auto Eat tiers heal up to upper thresholds of 40%, 60%, or 80% depending on tier.
• The wiki notes that food healing amount does not matter for Auto Eat survival as long as enough food exists; Auto Eat consumes enough pieces to reach the threshold.
• Auto Eat, Hitpoints, and Damage Reduction determine what content can be idled safely.

Death penalty

Combat death happens when damage reduces HP to 0 or below.

Death penalty:

• A random equipment slot is selected.
• If an item is equipped in that slot, it is lost forever unless Protect Item prayer applies.
• If ammo or summoning tablets are lost, the entire stack in that slot is forfeited.
• Only non-food equipped active-slot items can be lost.
• If the selected slot is empty, the player may lose nothing.
• Decoy Idol can absorb the loss if equipped.
• Hardcore mode has stricter consequences: the wiki states Hardcore characters are deleted upon death.

Loot

Combat area and slayer area monsters:

• Drop bones.
• Can drop GP/items based on monster drop tables.
• Loot must be manually collected unless using Amulet of Looting.
• Loot container has stack limits; older drops can disappear if too many stacks accumulate.
• Shop upgrades can improve loot container stacking.

Dungeons:

• Most dungeon monsters do not drop normal loot per kill.
• Dungeon rewards are granted after the final monster is defeated and sent to the Bank.
• God Dungeons are an exception in that shards are rewarded after each killed monster.

Dungeons, strongholds, and late combat

Combat content is segmented into:

• Combat Areas.
• Slayer Areas.
• Dungeons.
• Strongholds.
• The Abyss / Abyssal content.

Dungeons are fixed sequences of monsters. Shop settings can enable Auto Restart Dungeon. Major dungeons gate progression through gear, lore, passive slots, and expansion unlocks.

Strongholds are a newer combat-zone type introduced around v1.3, with the wiki noting some pages need more completion.

Barrier

Barrier is an Atlas of Discovery combat mechanic.

Mechanics:

• Some monsters have a secondary health bar called Barrier above normal HP.
• Barrier must be dealt with through relevant damage/tools before normal combat proceeds efficiently.
• AoD adds a Summoning familiar and many synergies around Barrier.
• Barrier is one of the main combat differentiators in Atlas of Discovery.

Abyssal damage and resistance

Into the Abyss introduces:

• Abyssal Realm monsters.
• Abyssal Damage.
• Damage & Resistance mechanics.
• Abyssal combat areas, slayer areas, strongholds, and the Abyss challenge.

This creates a late-game parallel progression track after Impending Darkness.

Magic sub-systems

Standard Magic

Standard Magic uses runes and magic equipment to deal combat damage.

Progression:

• Magic level unlocks spells, weapons, armour, and utility.
• Runecrafting supplies runes.
• Combat Magic trains Magic through damage dealt.

Ancient Magicks

Ancient Magicks are powerful offensive spells.

Mechanics:

Auroras provide player buffs in combat.

Mechanics:

• Automatically cast on every attack turn.

Equipment and item upgrading

Equipment provides combat stats and modifiers.

Equipment concepts:

• Weapons determine attack type, attack styles, special attacks, and attack interval.
• Armour contributes defence/evasion/damage reduction and level requirements.
• Jewellery gives combat and skilling bonuses.
• Cape slots include skillcapes and completion capes.
• Passive slot unlocks after beating Into the Mist.
• Atlas adds a Gem Slot.
• Into the Abyss adds new gear tiers and Abyssal gear.

Item upgrading:

• Upgrading items, also called trimming, improves items.
• Upgrades are performed from the Bank item menu.
• Upgrade windows show resulting stats and costs.
• Some items can be downgraded, such as perfect cooked food into normal variants, Charge Stone of Rhaelyx into Mysterious Stone, and Bundle of Rope into Rope.
• Potions generally upgrade tier by combining lower-tier potions.

Completion systems

The Completion Log tracks progress toward completing the game.

Completion categories:

Skills: skills in an expansion must reach max level for that expansion.

Mastery: each skill action must reach level 99 mastery.

Items: each item must be found at least once.

Notable exclusions from completion include Township tasks, special event items, completion capes themselves, corruptions, spells, and certain lore/easter egg/shop categories depending on wiki rules.

Pets

Pets are unlockables with permanent bonuses.

Mechanics:

• Pets do not appear in the Bank.
• Unlocked pets appear in the Pets section of the Completion Log and sometimes the skilling minibar.
• Once acquired, a pet’s effect is permanently active and cannot be turned off.
• All unlocked pets are active simultaneously.
• There are skill pets, boss pets, Township pets, and other special pets.
• Skill pet chance is based on action time, virtual skill level, and increased pet chance modifiers.
• Combat skill pets roll on successful damaging hits, with special rules for Prayer, Slayer, Corruption, and multi-hit attacks.

Pets are both functional bonuses and completion goals.

Production chains and dependencies

Melvor’s depth comes from how skills feed one another.

Food/survival chain

Fishing catches raw fish.

Farming grows food and ingredients.

Cooking turns raw/farmed items into food.

Food is equipped from the Bank.

Manual eating or Auto Eat consumes food in Combat/Thieving.

Better food and Auto Eat enable safer idling of stronger enemies.

Melee gear chain

Mining gathers ores.

Smithing smelts bars.

Smithing crafts melee weapons/armour.

Attack/Defence levels unlock equipment.

Better melee gear enables harder monsters/dungeons.

Ranged gear chain

Woodcutting gathers logs.

Mining/Smithing may supply arrowheads or metal components.

Fletching creates bows/ammo.

Crafting creates ranged armour and jewellery.

Ranged level unlocks equipment.

Magic chain

Mining gathers rune essence and materials.

Runecrafting creates runes and magic gear.

Magic consumes runes in combat or Alternative Magic.

Curses/Auroras/Ancient/Abyssal spell systems add layers.

Runecrafting and rune preservation reduce bottlenecks.

Potion chain

Farming grows herbs.

Combat/thieving/skilling collect secondary ingredients.

Herblore brews potions.

Potions apply combat or skill bonuses.

Auto re-use enables idle use.

Mastery and upgrades improve potion tier/effectiveness.

Passive optimization chain

Agility obstacles provide global passives/tradeoffs.

Astrology constellations add broad bonuses.

Summoning familiars/synergies add action-specific bonuses.

Pets add permanent bonuses.

Skillcapes add level 99/120 perks.

Mastery checkpoints add skill-level bonuses.

Shop upgrades improve tools/action efficiency.

Major progression gates

Important gates and bottlenecks include:

• Bank slots and storage capacity.
• Tool upgrades: axe, pickaxe, fishing rod, archaeology tools, harvesters.
• Auto Eat tiers for idle combat.
• Food supply.
• Damage Reduction thresholds for safe combat.
• Gear tiers and item upgrades.
• Prayer point supply.
• Rune supply and rune preservation.
• Slayer gear and area-effect negation.
• Dungeon completions.
• Into the Mist for Combat Passive Slot.
• Impending Darkness for Into the Abyss access.
• Completion capes requiring expansion-specific 100% completion.
• Abyssal Skill Trees and Abyssal level caps in ItA.

User interface structure

The Beginner’s Guide describes the interface as four major regions:

• Left menu: skills, combat, information pages, Bank, Settings; skill list can be shown/hidden.
• Top bar: current page, potion/equipment icons, account/cloud status.
• Right bar / skilling minibar: pets, quick equip, summoning synergy, milestones, mastery unlocks, Ancient Relics, expand/collapse.
• Main section: selected skill, Bank, Settings, information pages, combat UI, etc.

The UI is central to the game because most gameplay is menu/action selection rather than world navigation.

Settings and save management

Settings include:

• Notifications.
• Dark mode and display options.
• Save management.
• Offline combat/thieving enablement.
• Dungeon auto-restart settings.
• Various quality-of-life options.

Melvor Cloud is recommended by the Beginner’s Guide:

• Register/login from the game.
• Logging in automatically backs up the save when entering the game unless disabled.
• Cloud is also required to synchronize expansion purchases across platforms.

Mod support

Official mod support was added with Throne of the Herald’s stage 1 update.

Features:

• In-game mod browser.
• Cross-platform mod support.
• Mods can change offline caps, quality-of-life, UI, mechanics, or progression.

Caveat:

• Modded behavior can diverge from wiki/default mechanics.
• Some wiki pages reference mods as optional/at-own-risk ways to alter default mechanics.

Strategic early-game notes from the researched guides

The Beginner’s Guide emphasizes:

• Set up Melvor Cloud early.
• Learn the Bank and Shop quickly.
• Start with basic resource chains like Fishing -> Cooking.
• Fishing Raw Shrimp and Cooking Shrimp teach the basic active skill loop.
• Combat needs food and eventually Auto Eat.
• Bank slots are an early bottleneck.
• Guides can be out of date, so check the version listed on each guide.

Practical early priorities implied by mechanics:

• Produce reliable food.
• Buy Auto Eat as soon as feasible for safer idle combat.
• Upgrade gathering tools.
• Maintain bank space.
• Train Mining/Smithing for early melee gear or Fishing/Cooking for sustain.
• Use Wiki “What links here” to avoid selling items needed later.
• Start Farming early because it runs passively and supplies herbs/food.

Design takeaways

Melvor Idle’s core design is an optimization web:

• Every skill either produces resources, consumes resources, grants passive bonuses, unlocks combat power, or contributes to completion.
• Idle progression makes planning more important than moment-to-moment execution.
• Mastery means the same skill has both broad level progression and narrow per-action progression.
• Combat safety is a math/planning problem: HP, Auto Eat, food quantity, damage reduction, attack type, enemy max hit, and death penalty.
• The game uses multiple currencies and shops to structure mid/late-game upgrades.
• Expansions add not just more items, but new layers: 120 caps, map/excavation, Barrier, Ancient Relics, Abyssal Realm, Corruption, Harvesting, Skill Trees.
• Completionism is a first-class endgame, not an afterthought.

Caveats and gaps

• Several wiki pages are marked “possibly not up to date” or “incomplete”; this is especially relevant for some v1.3 / Into the Abyss pages.
• This research used public web/wiki documentation and did not inspect a live save file or play through current in-game UI.
• Some numerical formulas, drop rates, and best methods change with balance patches; for exact optimization, consult current in-game data, wiki data tables, or calculators.
• Modded saves may behave differently from the default mechanics described here.
