HIT POINTS
A creature's maximum HP is derived from its Vigour with diminishing returns, scaled by the species? ' HP multiplier:
max HP = floor( sqrt(VIG) x hp_multi x 6.325 )
hp_multi defaults to 10 when a species has no explicit value. Because HP scales with the square root of VIG, doubling VIG multiplies HP by about 1.41×.
THE DAMAGE FORMULA
Attack is reduced by the target's effective Defence as a percentage:
defence multiplier = 100 / (100 + effective DEF)
base damage = max( 1, floor( attack x defence multiplier ) )
damage = floor( base damage x trait multipliers x variance )
Variance is ±15%, so identical attacks differ slightly. Damage is always at least 1.
| Effective DEF | Damage taken | Reduction |
|---|---|---|
| 0 | 100% | 0% |
| 25 | 80% | 20% |
| 50 | 67% | 33% |
| 100 | 50% | 50% |
| 200 | 33% | 67% |
EFFECTIVE DEFENCE
Several effects lower the Defence used in the formula:
- Armour Break — cuts Defence by 30% (per source).
- Stun — the guard drop cuts Defence by 30%.
- Rend — removes a flat amount of Defence per stack (default 5 per stack).
- Defence Ignore (passive/effect) — ignores a percentage of the target's Defence outright (capped at 90%).
OFFENSIVE MULTIPLIERS
After the base hit, these stack on top:
- Crit — from crit passives; default 15% chance for a 1.5× hit unless the creature's passive says otherwise.
- Pack bonuses — extra damage for each living ally of the right species (a per-ally bonus, optionally capped).
- Low-HP / execute — bonus damage against wounded targets (e.g. +50% under 30% HP).
- Missing-HP scaling — damage grows as the attacker itself loses HP (up to a cap).
- Speed superiority, first strike, kill streak, vengeance, ramp-up — all feed a single additive bonus percentage.
- Weaken on the attacker reduces outgoing damage (default −25%).
MITIGATION & REFLECT
Incoming damage is reduced in order:
- Invulnerable — takes no damage at all.
- Shield — soaks a fixed pool of damage, then breaks.
- Damage Reduction status — a percentage cut.
- Passive reduction (Damage Dampening, Protector, Guardian) — capped at 60%.
- Ally auras (Guardian, Team Bulwark, Mobile Base) — a further party? -wide cut, capped at 60%.
Reflect bounces a percentage of dealt damage back to the attacker (status + thorns passives, multiplied by Retribution-style boosts, capped at 150%).
MISS, DODGE, BLOCK
- Blind on the attacker — default 50% miss chance, reduced by accuracy bonuses.
- Dodge on the target — the status' stated chance is honoured exactly, plus any evasion passives stacked on top. Pure passive evasion (no dodge status) is capped at 50%.
- Stun immunity and blocked buffs stop specific effects from landing (see Status Effects).
