Fire strike
Heinrich spends his remaining HP to land a deadly attack on the enemy, dealing P.ATK*(remaining HP/50000＋2500%) as P.DMG. Uses up all [Charge] stacks, each stack increasing DMG by 10%. After casting this skill, loses 80% of current HP. If the skill kills the target, restores the amount of HP the target had before hit for Heinrich. The cooldown is fixed. [Disaster Fire Strike] ignores the target's DMG reflection, DMG negation, flee, and death negation.

Damage formula
How each damage event is calculated, including level scaling, defenses, penetration, criticals, target modifiers, and caps.
Client formula mapped
Level 1 coefficient
2,500%
×25 per damage event · Lv. 1: 2,500%
Damage events per cast
6 damage events
Each event runs through the formula separately.
Fire Strike client formula Calculation order

Per event = physical attack lane × {(25 + Current HP ÷ 50,000) × (1 + 0.10 × Charge stacks)} × applicable AA Damage, Unyielding, refine, short-range, element, race, size, and MVP factors − target VIT; each of the six events resolves independently.

HP and Charge scaling
(25 + Current HP ÷ 50,000) × (1 + 10% per Charge) in PvE
Physical DEF
Applied to normal events; a White Star critical event ignores Physical DEF
Attack element
Inherited from Heinrich’s current attack element; the skill is not locked to Fire
Critical behavior

White Star lets each event critical independently. At White Star Lv. 7, each eligible equipped long or short sword adds 35% Crit Rate; from Lv. 4, every Charge adds another 3%. A critical event ignores Physical DEF and applies Heinrich’s Critical Damage against the target’s Critical Damage Reduction.

Key mechanics

PvE current-HP term
Monsters use Current HP ÷ 50,000 in full. PvP and GvG quarter only that HP contribution before Charge scaling.
White Star and Unyielding
White Star Lv. 7 applies Heinrich’s Auto Attack Damage bonus. While Unyielding is active and Heinrich has at least 60% HP, the coefficient gains 5% per Unyielding level.
Six independent events
The 2,500% base and current-HP scaling are evaluated six times. All Charge stacks are consumed after the cast instead of turning the skill into one combined hit.
Monster HP protection
Eternal Night prevents Fire Strike’s 80% current-HP cost against monsters and grants temporary immunity to Physical Damage, Magic Damage, and HP Loss. Without that monster trigger, the current client cost is 80%—not a drop to 1 HP.
Element choice
Fire Strike reads Heinrich’s current attack element. Against a Water target such as Ice-Forged Bagg, use Wind rather than assuming the skill name forces Fire damage.
MVP HP-loss limits
Target damage reduction and Real HP Break limits still apply to every event. A large floating number does not bypass Ice-Forged Bagg’s actual HP-loss ceiling.
