Battle formulas

• Basic attackAttack × random 0.85~1.15 × K ÷ (K + target defense)×1.6 on a crit. Then the target's race and personal damage-taken multipliers apply. A landed hit does at least 1.
• SkillAttack × skill multiplier × random 0.9~1.1 × K ÷ (K + target defense)Crits and damage taken work as above. Skills never roll dodge.
• Defense constant KNormally 100. When enemies strike from floor 400, K = 100 + 150x + 75x², where x = (floor − 400) ÷ 100.Tower climbs only. Floors reached before 1.25.0 stay at 100, and the new formula ramps in over the next 50 floors.
• Late tradeFrom floor 301, enemy HP ×0.8 and enemy attack ×1.2.Boss Hunts, personal trials and raids skip it.
• LifestealBasic attacks heal damage dealt × lifesteal rate.
• Firepower FocusAttack skills see enemy defense at ×0.75.

Stats guide

Rules within one battle. The receiver keeps the count, and values multiply. Once the slots are full later skills do not apply, so the earlier values stay.

• Attack and defense buffs2 attack and 2 defense per merc. The slots are separate, and different skills share the count.
• Defense reduction (corrosion)3 per enemy, shared across skills. 12% by default, and some skills differ.
• Dodge reductionThe value comes straight off. The detector takes 10 each, 2 per enemy, never below 0. Some skills apply only once.
• Bard ×2Attack +15% each, +32.25% total
• Rien Silvas ×2Attack +12% each, +25.44% total
• Alchemist ×3Defense −12% each, −31.9% total
• Rien Silvas ×3Defense −10% each, −27.1% total

Skill table

• Action gaugeFills by speed each tick. At 100 the unit acts.
• EnergyMax 100. +26 per basic action, +9 per hit taken. Bosses start at 40. When full, the unit uses its skill instead of a basic action.
• Healing actionHealer classes heal the ally with the lowest HP ratio when that ally is under 85%, for attack × 0.9 × random 0.85~1.15. If nobody qualifies, they attack.

• Front-targeting classesA random enemy in the front row. If it is empty, the back row.
• Back-targeting classesA random enemy in the back row. If it is empty, the front row.
• Free-targeting classes60% of the time the enemy with the lowest HP ratio, otherwise random.
• TauntWhen a back-targeting or free-targeting class attacks and Knight · Monk stand in the opposing front row, they pull the hit 35% of the time.

Targets by class

• Tick capsNormal battle 180, raid 180, Boss Hunt squad 120, final trial 100.
• Time outIf both sides still stand at the cap, you withdraw from that floor. Fallen mercs are only injured, never killed. An Abyss ritual counts as a withdrawal and returns the shards.
• Cause shownThe result screen names the cause. Healing if enemies regained 60% or more of damage dealt, wards if 20% or more of hits were blocked, dodge if 35% or more of attacks missed, otherwise not enough damage.

• ClutchAt 30% HP or less, basic attacks multiply attack by the clutch value. Abyssals have ×1.2; others get it from traits.
• MoraleBelow 30 morale, attack ×0.9. Above 85, attack ×1.06.

Traits

• Combat powerOffense × 20 + sustain × 14 + durability × 3
• OffenseAttack × action rate × (1 + crit% × 0.6). Healers use attack × action rate × 0.35.
• SustainHealers: attack × action rate × 1.45. Lifesteal adds offense × lifesteal rate.
• DurabilityHP × (1 + defense ÷ 100) × (1 + dodge% × 0.7)
• Action rateSpeed ÷ 20, at least 0.35.

Ally power ÷ estimated enemy power is compared with the edges below. At or above an edge you get that verdict; below the fourth edge it is “Deadly”. Edges between floors are interpolated.

• “Dominant” limitWith hidden enemies or a missing floor counter, the verdict stops at “Favored”.
• “Favored” limitWith fewer than 4 mercs or no front row while outpowered, the verdict drops to “Even”.

• Defeat notesDamage under 55% of total enemy max HP, or no kills, is called out as low damage; under 65% suggests more firepower. Healing under 12% of enemy damage suggests a healer. Fewer than 4 mercs suggests a full party. No front row, or a wiped one, suggests a front line.
