Well, it's supposed to have a 20% chance to cast faerie fire. I based it off of feedback... Coruption = Feedback

Casting unit and target unit of ability being cast. There are no attacking/attacked units.



Also, in this case it would probably be safer to use 'starts the effect of an ability' instead of 'begins casting...,' since begins casting can be cancelled before the CD or mana cost are set off.

wait... So what's wrong and how do i fix it..?

A unit is attacking, the tower.

What's wrong is that your event is 'A unit starts casting an ability' and you have event responses 'attacked unit' and 'attacking unit.' The event needs to be 'a unit is attacked' for 'attacked unit' and 'attacking unit' to work. The event you're using has the equivalents 'casting unit' and 'target unit of ability being cast'.


Unless of course corruption is actually an on-attack ability from a tower, which ytou should have mentioned earlier but didn't, at which point you either need a damage detection system or, alternatively, you could just give the tower an ability based off of the 'orb of lightning' ability which uses a faerie fire ability instead of purge.
