How do you want it?
Edit: Never mind, someone is really fast it seems. Though one issue, you should use percentage maybe? Unless it is going to be exactly like an AoS normally is.
Also why not just kill the unit instead of dealing a billion damage?
You should also put the condition in the main condition check to let it know that its an ally in the top so it doesn't run for enemies because as it is it will stop the attacker on both allies and enemies.
