you could trigger the whole spell.
But I am still not sure how to check when the fireball hits :/
Use a dummytype you don't use for anything else.I suggest using a dummy spell?
Like fireball with no damage?
But I am still not sure how to check when the fireball hits :/
I think it would work if you would set "unit is attacked" event and "unit has buff" condition - with phoenix fire as buff since whenever a unit gets hit by phoenix fire,it gets buff.
(Didn't test it,but i think it works)
Okay, how would you trigger the projectile going from the source to the target?
