This Melvor Idle 2 combat guide details core battle formulas, hit chance calculations, weapon stance experience gains, and defensive armor mechanics. Understanding combat formulas allows players to calculate accuracy ratings, maximum hit limits, and damage mitigation.
Combat Engine
Combat mechanics in Melvor Idle 2 are developed by Games by Malcs and published by Jagex. The full game release encompasses 25 skills, an eventual level cap of 99, over 1,800 items, and more than 150 monsters. In the current demo build, combat and non-combat skills are capped at level 60 through the game experience component. Player combat level represents overall battle capability derived mathematically from your combat skill ratings.
The game engine calculates combat level using ratio weights across Attack, Strength, Defence, Ranged, or Magic depending on your style. Effective combat level from ratios is computed by summing the level multiplied by ratio without applying a floor operation. Modified combat level evaluates to the truncation of base skill level plus any flat bonus modifiers. Modified combat stats calculate from base values plus flat additions multiplied by percentage modifiers. An enemy monster combat level is determined by taking the maximum combat level across the styles of its active stances. A player base stat total equals the sum over equipped items of stats according to combat formulas.
Combat Styles
The combat engine defines Melee, Ranged, and Magic combat styles. The Melee style calculates combat level using ratio weights of 0.325 for Attack, 0.325 for Strength, and 0.25 for Defence. Melee accuracy levels depend strictly on the Attack skill with a ratio weight of 1. Melee evasion levels depend on the Defence skill with a ratio weight of 1. The Ranged style computes combat level through a ratio of 0.4875 for Ranged and 0.25 for Defence.
Ranged accuracy scaling relies upon the Ranged skill with a ratio weight of 1. Ranged evasion scaling similarly depends directly upon the Defence skill with a ratio weight of 1. The Magic style determines combat level by combining a 0.4875 ratio for Magic and a 0.25 ratio for Defence. Magic accuracy levels scale with the Magic skill with a ratio weight of 1. Unlike physical styles, Magic evasion levels incorporate both Defence with a 0.3 ratio and Magic with a 0.7 ratio.
Combat Triangle
When a Melee attacker faces a Ranged defender, the combat triangle grants a 10% increased maximum hit and 15% increased resistance advantage. Attacking with Ranged against a Magic target similarly yields a 10% increased maximum hit and 15% increased resistance modifier. Engaging in combat using Magic against a Melee opponent awards a 10% increased maximum hit alongside a 15% increased resistance bonus.
| Matchup | Player Style | Enemy Style | Advantage Status | Combat Modifiers |
|---|---|---|---|---|
| Melee vs. Ranged | Melee | Ranged | Advantage | 10% Increased maximum hit; 15% Increased resistance |
| Ranged vs. Melee | Ranged | Melee | Disadvantage | 10% Increased maximum hit; 15% Increased resistance |
| Ranged vs. Magic | Ranged | Magic | Advantage | 10% Increased maximum hit; 15% Increased resistance |
| Magic vs. Ranged | Magic | Ranged | Disadvantage | 10% Increased maximum hit; 15% Increased resistance |
| Magic vs. Melee | Magic | Melee | Advantage | 10% Increased maximum hit; 15% Increased resistance |
| Melee vs. Magic | Melee | Magic | Disadvantage | 10% Increased maximum hit; 15% Increased resistance |
Attack Stances
Within each combat style, characters adopt specific attack stances that dictate accuracy stats, evasion stats, and experience rewards. Per point of damage dealt, each skill listed in the attacker stance experience roster receives proportional experience. The Stab melee stance utilizes Stab Attack Bonus for accuracy and Stab Defence Bonus for evasion. Attacking with Stab awards 0.133 Hitpoints experience and 0.4 Attack experience per point of damage dealt. The Slash melee stance leverages Slash Attack Bonus for accuracy and Slash Defence Bonus for evasion. Striking with Slash distributes experience across three skills, awarding 0.133 Hitpoints, 0.12 Attack, and 0.28 Strength per damage. The Crush melee stance relies on Crush Attack Bonus for accuracy and Crush Defence Bonus for evasion. Engaging enemies with Crush grants 0.133 Hitpoints experience and 0.4 Strength experience for each point of damage inflicted.
The Block melee stance utilizes Block Attack Bonus for accuracy and Block Defence Bonus for evasion. Defending with Block provides 0.133 Hitpoints experience and 0.4 Defence experience per point of damage scored. The Accurate ranged stance grants 0.133 Hitpoints experience and 0.4 Ranged experience per damage point. The Powerful ranged stance awards 0.133 Hitpoints, 0.28 Ranged, and 0.12 Strength experience per damage point. The Long-Range stance distributes 0.133 Hitpoints, 0.28 Ranged, and 0.12 Defence experience per damage point. The Empowered magic stance awards 0.133 Hitpoints experience and 0.4 Magic experience per point of damage dealt. The Focused magic stance grants 0.133 Hitpoints, 0.28 Magic, and 0.12 Defence experience for each damage point scored.
Accuracy Mechanics
Landing attacks in Melvor Idle 2 requires evaluating attacker accuracy against defender evasion ratings. Your accuracy rating scales with your active combat style level and your weapon’s stance attack bonus. Modified accuracy rating applies percentage modifiers and reduces accuracy under darkness penalties up to a cap of 20 darkness. Defending targets maintain a distinct evasion rating against each attacking stance based on their Defence level and defensive equipment bonuses. Modified evasion rating applies percentage and flat modifiers and reduces rating by 0.05 per darkness clamped between 0 and 20. The defender maintains one evasion rating per attacker stance where the active attacking stance picks which rating applies.
When attacker accuracy meets or exceeds defender evasion, hit chance is calculated by comparing evasion to accuracy. Special attacks marked as unavoidable bypass accuracy checks entirely to always hit the target. Players can test precise hit chance percentages against any enemy by using our web combat simulator.
| Combat Metric | Determining Variables | Engine Formula |
|---|---|---|
| Base Accuracy Rating | Ratio level L, stance accuracy stat S |

Maximum Hit
For the Melee and Ranged styles, maximum hit increases with your Strength or Ranged level and your total Melee Strength Bonus or Ranged Strength Bonus. For the Magic style, base maximum hit scales with your chosen spell damage, your Magic Damage Bonus from equipment, and your Magic level. Final maximum hit modifies base damage by applying percentage bonuses, flat modifiers, and combat triangle adjustments. Minimum damage evaluates from flat additions and a percentage of max hit clamped between 1 and max hit. Attack interval dictates weapon strike frequency and is clamped to a minimum duration of 250 ms. Unarmed strikes default to a base attack interval of 4,000 ms.
| Damage Metric | Key Scaling Variables | Engine Formula |
|---|---|---|
| Melee / Ranged Max Hit | Level L, Strength Bonus B |
floor(22 + L + (L + 17) * B / 64) |
| Magic Max Hit | Spell Max Hit M, Magic Damage Bonus D, Level L |
floor(M * (1 + D) * (1 + (L + 1) / 200)) |
| Minimum Hit | Flat Min Hit, Max Hit, Min Hit Percent | clamp(trunc(floor(1 + flatMinHit + maxHit * minHitBasedOnMaxHit)), 1, maxHit) |
| Attack Interval Cap | Style attack interval stat base |
max(floor(base * (1 + percent) + flat), 250) ms |
Damage Mitigation
Damage mitigation evaluates from defensive armour and protection rating for the attack’s damage type. Armour stat provides flat damage reduction against incoming strikes according to the defensive style armour total. Armour is ignored once broken when an incoming hit deals modified damage greater than or equal to the armour value. An enemy base armour stat evaluates as the highest armour value across its combat styles. Resistance calculates percentage damage reduction from attacker power rating and defender protection rating. Power rating evaluates from equipment power ratings and scales with flat bonuses and percentage modifiers. Resistance damage reduction has a base cap of 0.7 before factoring in combat triangle multipliers. Darkness penalties in hazardous dungeon environments evaluate from area darkness minus equipped light sources.
When an attack connects, damage evaluates as the sum over its damage entries of a roll uniform inclusive in min and max. Normal damage bounds roll between truncated min hit percent and truncated max hit percent. Damage calculations check critical hit multipliers before testing attack damage negation. Final damage calculation multiplies damage dealt and damage taken modifiers and reduces damage by resistance and armour unless broken.
Hitpoints Scaling
Character maximum hitpoints scale directly from your Hitpoints skill level to determine maximum survivable damage. Base maximum hitpoints evaluate as your Hitpoints level multiplied by 10. Modified maximum hitpoints apply percentage equipment bonuses and flat hitpoint modifiers to increase total health. Turn-counting combat effects such as damage over time, stuns, and stacking modifiers encompass 52 distinct effects. Combat encounters can involve enemy passives where 116 of 155 enemies have one passive.
