* Adversarial Challenger Stress Testing 2 — Cohort 3: Necromancer Poison & Bone (IDs 76..85 / 67, 68, 73, 74, 78, 83, 84, 88, 92, 93)
|
||
*
|
||
* EMPIRICAL ADVERSARIAL STRESS SUITE:
|
||
* 1. Corpse Explosion:
|
||
* - 70%–120% monster base HP damage split into 50% physical + 50% fire.
|
||
* - Invariance: Damage does NOT scale with multiplayer health multiplier (must use single-player base monster life).
|
||
* - Radius: Scales at +0.33 yards/lvl (+1 subtile/lvl) starting from 2.66 yards at slvl 1.
|
||
* - Corpse consumption: Consumes corpse; cannot explode already consumed corpses.
|
||
* 2. Poison Nova:
|
||
* - Duration: Strictly 50 frames (2.0s) duration in 1.13c; does NOT increase with level.
|
||
* - Synergy: +10% poison damage per hard point in Poison Dagger and Poison Explosion.
|
||
* - Missiles: Spawns exactly 64 radial poison bolts in 360-degree ring.
|
||
* 3. Bone Armor:
|
||
* - Absorption: Absorbs physical damage only (elemental/poison bypasses).
|
||
* - Capacity: 20 base + 10/lvl, plus +15 absorb per hard point in Bone Wall / Bone Prison.
|
||
* - Collapse: When damage exceeds remaining absorb, absorbs remaining amount, drains pool to 0, and removes Bone Armor state.
|
||
* 4. Bone Wall & Bone Prison:
|
||
* - HP scaling: 19 base + (slvl-1)*4.6, multiplied by synergies.
|
||
* - Duration: Exactly 24.0s (600 frames).
|
||
* - Obstacle: Blocks unit movement and non-piercing missiles.
|
||
* 5. Teeth & Bone Spear & Bone Spirit:
|
||
* - Teeth: Multiple teeth fan, max 24 teeth; single target can only be damaged by 1 tooth per cast.
|
||
* - Bone Spear: Line projectile with collideKill=0 (pierces all targets in its path).
|
||
* - Bone Spirit: Homing missile tracking nearest target in 2:1 isometric ground perspective.
