STATUS-003computeEffectTick

stack_intensity policy — 5 stacks of a bleed-style DoT scale damage by stack count

Tests that Effects with stackingPolicy='stack_intensity' use the stacks field to multiply Modifier values OR tick damage. This scenario uses tick damage scaling. Demonstrates that 5 stacks of bleed deal 5x the per-stack damage.

Expected output

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

tickDamage: pending

tickDamage = stacks(5) * floor(4500 * 0.005) = 5 * 22 = 110. Verify the library's expression evaluator handles 'stacks' as a bound variable.

after stacks	110
floor + max(0)	110

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