STATUS-005computeEffectTick

DoT snapshot=true — Burn tick uses caster's stats at apply time

Inverse of STATUS-004. When snapshot=true, tick damage is computed from the snapshotState captured at apply time, not from current state. Even if the caster (or target) gets buffed later, ticks use the frozen values.

Expected output

From the scenario fixture. Numerical values marked as null are placeholders pending rAthena verification.

tickDamage: pending

tickDamage = floor(220 * 0.4 + 80 * 0.5) = floor(88 + 40) = 128. Element multiplier may apply on top depending on whether burn ticks go through the magical pipeline or are 'misc' fixed damage — document.

Stack-aware formulas (e.g. stacks * floor(maxHP * 0.005)) handle scaling themselves; the library does not auto-multiply.
