Hey! I have a little problem.
When an ability (i.e. Frost Bolt) is given to a specific unit, how do I make the ability being autocast, like the Heal ability? So it will automatically be cast when it is recharged?

-Thanks in advance.

Make an ability based on Curse with the desired mana cost, cooldown, icon, tooltips, targets, range, etc., duration 0.01 and a custom buff that says nothing.
Make a dummy unit (based on disease cloud, with only ability Locust), make your ability and then make a trigger that makes the dummy unit to cast it on the hit by the Custom Curse targets.

if you dont want to use a dummy you could just use:

event - unit is being attacked

condition - attacking unit equal to (unit which has frostbolt)

action - order attacking unit to (order string of the spell) attacked unit
