Fighters

Fighters are the combatants in a Cowculator battle. Their configuration combines resources, combat stats, active skills, passive skills, and an optional fallback skill.

Fighter stats

Each fighter has resources and combat stats that determine how they act and respond during battle:

Stat	What it controls
maximum_health	Health capacity and the default starting health
initial_health	Optional starting health. It defaults to maximum_health when omitted
maximum_energy	Energy capacity and the default starting energy. It defaults to 0 when omitted
initial_energy	Optional starting energy. It defaults to maximum_energy when omitted
attack	Base offensive strength used by attacks and some healing effects
defence	Mitigation of incoming normal damage
speed	How quickly the fighter's turn meter increases
critical_rate	Base chance for an attack to become critical
critical_damage	Damage multiplier applied on a critical hit
critical_resistance	Reduction applied to an attacker's critical chance
damage_multiplier	General multiplier applied to outgoing attack damage
damage_reduction	Reduction of incoming normal damage
dot_reduction	Reduction of incoming damage-over-time effects
regeneration.health	Ordered end-of-turn health regeneration components
regeneration.energy	Ordered end-of-turn energy regeneration components

Starting resources let you begin a battle with an injured fighter or a partly filled energy bar. initial_health must be at least 1, and neither initial resource can exceed its maximum. Omit an initial value to start at the maximum.

Each regeneration component uses type: "percentage", a basis of current or maximum, and a non-negative fractional value. Cowculator adds the components for a resource and rounds the final total half up once. Stat buffs and debuffs can modify the combined health or energy regeneration total.

Skills

Field	Purpose
active_skills	Active skills used in the fighter's configured rotation. It defaults to an empty array.
passive_skills	Triggered effects that run automatically. It defaults to an empty array.
fallback_skill	Optional zero-cost skill used when the rotation is empty or the intended active skill is unaffordable

See the Skills guide for ordering, targeting, passive timing, and examples.

See Damage calculation for how these stats interact.
