Immolation on/off

Is there a way to catch unimmolation event or I need to use Issued order stuff...

Detect the order is the only way. You could periodically check for the buff it gives if that is any easier with what you're doing, but otherwise catch the order "immolation" and "unimmolation."

Ok tnx.

I already did it with orders, but I have a new problem now.
When unit runs out of mana it is not given unimmolation order?

EDIT:
What is damage interval for immolation?
Or better yet, how long is damage interval for immolation?

That's the problem with detecting orders with immolation. The best solution is detecting when the buff is off.

Damage interval is to define the frequency when the damage (and the FX as far as I know) is done.

Ha I found a solution.

I made immolation drain life instead of mana. (it was natural in this case)

And if unit dies unimmolation is automatically issued,
