Combat Mechanics

Resist Roll

P(resist) = clamp(
  resistStat × 0.0005
  + clamp((target.level − attacker.level) × 0.005, −0.1, 0.1)
  − attacker.accuracy
, 0, 0.9)

Non-physical damage types only. A successful resist fully negates the hit, with no mitigation applied. Physical attacks have no resist roll, only a miss/block roll. Beyond damage, the same kind of roll also decides whether a debuff or dispel lands on its target, using the resist stat that matches the effect (for example Defense for a physical debuff). This is why Accuracy helps land debuffs and dispels, not only damage.

Mitigation

reduction   = ⌈damage × clamp(mitigationStat × 0.0005, 0, 0.9)⌉
finalDamage = damage − reduction

Applies to all damage types when a hit lands (max 90% reduction). The mitigation stat depends on damage type:

Physical Block / Miss

P(miss) = clamp(
  clamp(baseBlock + defense×0.0001 + blockBuffs, 0, 0.8)
  + clamp((target.level − attacker.level) × 0.005, −0.1, 0.1)
  − attacker.accuracy
, 0, 0.9)

Situational Modifiers

WIS Heal Bonus

finalHeal = baseHeal + round(baseHeal × min(WIS × 0.004, 5.0))

finalHeal = baseHeal + round(baseHeal × min(WIS×3 × 0.004, 5.0))

Critical Heal

Direct critical heals apply only to skills that can target other players (shown as "Others Only" or "Self & Others" on the skill page). When they crit: 90%→×2.0, 10%→×3.0. Heal-over-time ticks can also crit for ×1.5. The chance is based on the caster's Critical Chance when the buff was applied.

Per-Field WIS Multipliers

Attribute Source Dispatch

Attribute Dispatch

Per-Field Scaling

Poison and disease damage-over-time effects add round(DEX×1.5) to the base tick. Poison Resist reduces both types. Disease Resist does not affect these damage ticks. Counter effects, critical ticks, and ward absorption apply afterward.

DoT counter decay: 3 counters full damage, 2 → ×0.8, 1 → ×0.6.

DoT critical ticks: damage-over-time ticks can crit for ×1.5. The chance is based on the caster's Critical Chance when the debuff was applied. Critical Resist reduces the bonus damage.

Interval Formulas

Haste Effects

Aggro

added = skillAggro + (skillAggro > 0 ? caster.maxHP : 0)
       + damage
       + round(stunChance × stunTime × 10)
       + round(fearChance × fearTime × 10)

Capped at target's current HP.

Rage Generation

Warrior and Rogue generate Rage from two sources:

• Dealing auto-attack damage: ⌊damage × 0.25⌋ per hit, capped at the target's current HP.
• Taking Normal-type damage: ⌊clamp(sqrt(damage) × 0.35, 1, 25)⌋ per hit. Same formula applies to Warrior/Rogue mercenary pets when they receive Normal damage.

Stun

Applies on a single roll against the skill's stun chance. Cannot apply while the target is already feared. Duration stacks: a new stun extends the existing stun end time rather than replacing it. Bear mounts have a 90% chance to resist any stun. Stunned players are dismounted.

Knockback

Applies only if neither stun nor fear took effect on the same hit. Pushes the target backward and applies a 0.25-second stun. Only applies when the level difference is less than 15. This cap is waived when the caster is a boss monster.

Ward & Mana Shield Priority

Ward absorbs direct damage first. Mana Shield absorbs any remaining direct damage. Ward also absorbs DoT ticks before HP loss. Ward pool size comes from the buff's WIS scaling (WIS×2).

Fear

Applies only if two independent rolls succeed: the skill's fear chance, then the target failing their fear resist roll. Duration is random between half and full fearTime. Fear resist accumulates from skills and equipment, capped at 100%. At 100% the target is immune.

Root

Fully stops movement. Unlike sleep, does not break when the target takes damage. Monsters attempt a self-break every 2 seconds: chance = magicResist / 1000, clamped between 5% and 95%. NPCs attempt a self-break every 1 second with a fixed 10% chance. Bosses and elite monsters automatically resist this debuff.

Sleep

Applied by debuff skills that reduce speed to −50 or below. Any direct damage hit or DoT tick immediately breaks the effect. Bosses and elite monsters automatically resist debuffs that reduce speed below −10. Every 6 seconds, an affected monster rolls to self-break: chance = magicResist / 1000, clamped between 5% and 95%.

Enrage

Non-spell skills only. Players deal 33% more damage below 50% HP. Monsters deal 50–75% more damage below 10% HP, rolled separately for each hit.

Parry

Parry is a timed counter. If an eligible player is casting Parry and has the attacker selected, a single-target Normal melee hit is blocked and countered. Counterdamage is half the health damage the hit would have dealt after mitigation, ward, and mana shield, rounded and capped from 1 to 5,000. Fully absorbed hits do not trigger Parry.

Assassination

Skills with this mechanic can only be used when the target is below 25% HP.

Weapon On-Hit Procs

Weapons with an on-hit effect trigger it at the listed probability on auto-attacks. Rogue players also trigger their offhand weapon's proc at 50% of its listed probability. Weapon proc effects do not trigger damage shields.

Ground AoE Damage to Pets & Mercenaries

Skills that telegraph a danger zone before detonating deal half of their listed damage to your mercenaries and companions. Damage dealt to players is unaffected.

Cleanse

Cleanse is cast on yourself or an ally and removes harmful debuffs. It cannot be resisted and is not affected by Accuracy. A cleanse only acts on debuffs whose element matches it. For example, a fire-and-cold cleanse removes fire and cold debuffs but not poison, disease, or magic ones.

Every debuff carries 3 counters and is fully removed only when its counters reach 0. How many counters one cast removes depends on that debuff's Cleanse Resist:

A debuff with counters left stays on the target and can be reduced further by cleansing again. For damage-over-time debuffs, losing counters also lowers each tick of damage, to 80% of full at 2 counters and 60% at 1 counter. Nothing the caster does, Accuracy included, changes how many counters a cleanse removes.

Dispel

Dispel removes beneficial buffs from its target. Players cast it on monsters to strip their buffs, and some monsters cast it on players and their pets. Whether it removes anything, and how much, is decided in two steps.

1. Landing. The target rolls to resist the dispel using the resistance stat for the dispel's element, adjusted by the level difference between caster and target and reduced by the caster's Accuracy. Higher caster Accuracy means the target resists less often. If the target resists, nothing is removed.

2. Removal, only when the dispel lands. On a player, all buffs are removed except the Rest buff. On a pet, all buffs are removed. On a monster, each buff is tested on its own and is removed only when a random value from 0 to 1 is greater than that buff's Dispel Resist after subtracting the caster's Dispel Resist reduction:

Dispel Resist reduction
  single-target spell:   Accuracy × 0.5
  single-target scroll:  clamp(round(Mastery% ÷ 5), 1, 20) × 0.01
  area dispel:           0

The reduction is the caster's lever for stripping a monster's resistant buffs. A spell uses Accuracy, while a scroll uses the caster's Scroll Mastery rank, where each rank lowers a buff's Dispel Resist by 1 percentage point.

Buff & Debuff Overwrite

When a buff that belongs to an overwrite group is applied, all existing buffs on the target in the same group expire immediately. No strength or level comparison is made. The overwrite is unconditional. For example, Divine Shield and Shield of Faith share the same overwrite group, so applying either one expires the other.

• Skills without an assigned overwrite group bypass this check and can stack freely.
• Multiple debuffs with different or no overwrite groups apply independently.
• Exception: when a pet casts an area buff, targets that already have any buff in the same overwrite group are skipped rather than overwritten. Player-cast buffs always overwrite.
• When multiple DoT skills are active on the same target simultaneously, each maintains its own counter stack independently.
