Ohh, I see. I kind of assumed a few things.
set TempPoint = Target Point of (Ability being Cast)
set TempGroup = Every Unit within (X) of TempPoint matching ((Owner of (Matching Unit) is an enemy of (Owner of (Triggering Unit)))
[Decided to use the Trigger Editer now]
Err, sorry, it's a Boolean. It wasn't exact.
(((Matching unit) belongs to an enemy of (Owner of (Triggering unit))) Equal to (==) True))
Edit: Archideas, instead of doing 200, then 275, then 350, you could've used math with
Pick, Bleh bleh within range of (125+(75*(Level of (Ability being Cast))). Just a suggestion for future ones, though.
