Ok so in my TD currently I am using trigger to make it so creeps get the behaviors to slow them and to burn them from water and fire turrets. But this is becoming a problem because say I get 20 of these towers, this starts making these triggers constantly running and if this happens I get an overload basically and they all stop running, all triggers that is. So what I need to do is make it so these behaviors are given via ability on the towers, kinda how the marauder, once upgraded, slows units it attacks.

I have done a little experimenting with this already but I didn't have much luck. So can someone help me understand how to get about doing this?

bump: anyone know how to do this? I really need to remove the triggers to optimize my map.

are you doing the " Play trigger over, in the same trigger"???
But I am pretty sure if you want to attach slowness to an attack you change its effects on the attack/ not the behavior on the unit. " Mess with stim pack, just make it go the opposite way and change it to a target attack, put some splah on that baby! "
Just start messing with that spell/ attaching it to the towers attack!!! I bet you could get it!

Okay, so I will describe what I see is going on with the marauder slow and how it works and maybe you'll be able to do something like that to satisfy your own needs.

In weapon data type the marauder weapon is called Punisher Grenades. In that weapon object in the effect field it runs an effect called MarauderLM. This effect is a launch missile effect, and in its Impact Effect field it runs the effect Marauder Concussive Grenade (set). This effect runs two other effects called Marauder Concussive Grenade (damage) and Marauder Concussive Grenade (slow). The slow effect is responsible for slowing down the targeted unit, and this can be seen in the field called Unit + which is set to Target.
