Thanks for that. But that's sorta what I have already. The problem with that being that I have to trigger it EVERY time a unit it attacked. That causes lag. Lag which I'm trying to get rid of.
I guess I wasn't specific enough, so here's a little more info on the task at hand:
I have a tower which has Missile(Bounce) and I have a trigger which causes the tower to DamageTarget any unit it hits dealing DamageDealt and then displaying the towers damage x2 in red floating text as if it were Critical Strike. The reason I took this approach is because if you use the actual Critical Strike ability it prevents the attack from bouncing any time the Critical Strike takes effect.
So as an alternative, to reduce the lag it produces, I'm trying to come up with a solution that I can trigger as the tower attacks. Not every time it hits (which includes every unit in the bounce).
The only thing I could come up with, but not get to work, was to change the damage loss factor to a negative value, in theory, increasing the damage it deals per bounce. Again, this failed.
Anything would help. Thanks.
