Healing Spray

Contract

ANhs is TFT-only CAbilityHealingSpray (parent ANcs Cluster Rockets). ROC AbilityData.slk has no row. It is a point-target channeled hero spell (AB_SPELL | AB_CHANNEL, SPELL_TARGET_POINT). Waves heal friendlies in Area while the Alchemist keeps channeling; movement or stun cancels remaining waves through S_SpellChannelActive.

Ubertip: sprays DataF waves; each wave heals DataA to all friendly units in an area. WorldEdit / Hive OE labels (gainedHP; frequency; missiles; maxGainedHP; buildDmgReduction; waves) map DataA–F.

Field	Stock L1/L2/L3	AbilityMetaData / OE	Runtime use
`DataA`	40 / 55 / 70	gainedHP	heal per unit per wave
`DataB`	1 / 1 / 1	frequency (seconds)	delay between waves
`DataC`	6 / 6 / 6	missiles	presentation; unresolved
`DataD`	280 / 385 / 490	maxGainedHP	per-wave shared heal budget
`DataE`	1 / 1 / 1	buildDmgReduction	unused (targs exclude structure)
`DataF`	3 / 4 / 5	waves	number of heal pulses
`Area`	250	—	blast radius
`BuffID`	`BNhs`	—	presentation; heal does not require it
`targs`	friend,self,ground,air,organic	—	living friendlies in area
`Dur` / `HeroDur`	0	—	unused; channel length is the wave schedule

First wave at cast (t=0), then every DataB seconds for DataF waves. Stock L1 ends at 2s (3 waves × 1s interval). Do not treat Dur as channel life.

When DataA * hit_count > DataD, per-target heal scales down so the wave total equals DataD (same shape as Blizzard / Cluster Rockets max damage per wave).

DataC missiles and DataE build factor are intentionally unimplemented until a correct presentation or negative-heal path is wired.

Data Flow

AbilityData.slk (ANhs, TFT only)
  -> DataA/B/D/F, Area, targs, Cost, Rng
CAbilityHealingSpray + S_SpellChannelThinker
  -> healing_spray_think pulses while S_SpellChannelActive
S_SpellHeal
  -> friend/self organic units in Area (via S_SpellAllowsTarget)

Diagnostic Workflow

build/bin/ability_audit -data 'data/Warcraft III' -raw ANhs

ROC prints AbilityData: not found; TFT prints the row above.

Verification

make test-wc3-engine WC3_PATTERN='wc3_spell.healing_spray*'

Focused tests use non-stock DataA/DataB/DataD/DataF so they cannot pass on hardcoded retail constants. They cover first-wave heal, max-heal scaling, second pulse via G_RunEntities, caster-move cancel, and enemy/mechanical miss.
