I created an ability that sends the caster to the target location with a missile effect, and having it apply and remove a behavior (on the caster) which deals damage to all units it passes through (periodic search with a damage effect). And I want to know if there is any way, to make the damage effect apply a marker, so that it will only be applied to the same unit once on that cast.

@Demtrod: Go

You could apply a behavior to the unit taking damage and then add that behavior in the search validator. Give the behavior an appropriate duration so it wears off before the next cast.

If you use a behavior on the caster to apply the damage, I am not sure how to do this with markers. However, if you use a Persistent effect instead, its pretty easy, just check the Match Flags -> ID for the persistent and add a No Markers validator to the damage effect.

@BasharTeg: Go This is what I'm currently doing, but it wont allow multiple instances of the ability to be run for a unit at the same time.

@Kueken531: Go Yeah, thanks :)

@DrSuperEvil: Go How would I determine which effect is the right one?

When I use a Destroy Persistent effect, I have to specify where to search and what radius to search in - how do I make sure I remove the right one?

@DrSuperEvil: Go

made it work by setting it to the Destroy Persistant target to the caster. Thanks :)

oh, yes - sorry for not checking it off.
