How to stack healing aura?

[WC3Wonderer]

I want to increate life regeneration rate by one hitpoint per second for every Priest. How to stack healing aura?

You’ll need variables and an Unit Indexer that assigns custom values as unique index on map Init

---

Variables:
—PriestGroup - unit group
—AuraUnits - unit group
—TempGroup - unit group
—TempP - point
—Target - unit
—TempInt - integer
—PriestCount - integer(array)

---

Create a dummy ability based on item life regen.

1. Create the dummy ability

— Base ability: Item Life Regeneration (or any ability that adds flat HP regen).
— Data – Life Regeneration: 1.00 (per level)
— Stats – Levels: 50 (or high enough for your max stack).
— Stats – Actively Used: False.
—Art – Button Position: set both X and Y to -11 (hides it from the command card).

The trigger runs every 0.5 seconds, which is light enough for most maps.
If you have many priests, you can increase the interval slightly (~ 1.0 second) the effect will still be smooth.

· Event‑based alternative: If you prefer, you can track priests entering/leaving range and update only affected units. That’s more efficient but also more complex.

Or simply use Life Regeneration Aura (Neutral) it stacks.
