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.

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

Applies only to skills that can target other players (shown as "Others Only" or "Self & Others" on the skill page). On crit: 90%→×2.0, 10%→×3.0.

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 first. Mana Shield absorbs any remaining damage. Ward pool size comes from the buff's WIS scaling (WIS×5).

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. When the caster's HP falls below 50% (monsters: 25%), their damage output increases by 33% (players) or 50–100% (monsters, random per hit).

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 removes debuff stacks from a target. Each debuff has a Cleanse Resist level:

Type matching: a cleanse skill only removes debuffs whose element matches (a poison cleanse only removes poison debuffs, etc.).

Dispel

When Dispel lands on a player, all active buffs are removed (except the Rest buff). On a pet, all active buffs are removed. On a monster, each buff is tested independently:

removed if Random.value > probIgnoreCleanse − bonus

bonus (single-target spell):   accuracy × 0.5
bonus (single-target scroll):  clamp(round(Mastery% ÷ 5), 1, 20) × 0.01
bonus (area dispel):           0

Mastery comes from the Scroll Mastery profession. Each Dispel rank lowers a monster's Dispel Resist by 1 percentage point. Area dispels do not get an accuracy or Scroll Mastery bonus.

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.
