Help with item ability

[4daHorde]

I'm working on a map and I'm trying to have an item with three charges that fires a projectile at an enemy that can bounce to other enemies a couple of times, each time weaker. I know how to make the charges, but I'm not sure what base ability to use this as. I tried using chain lightning, but even if I change all art files that say chain lighting to the projectile, the item affect doesn't show the projectile but instead shows the chain lightning. Please help, I don't know what to do. Thanks

There's no way to use chain lightning, you are right... You'll have to edit triggers

Done

hey there, it isnt impossible without triggers, ive attached a map to this post with the item and the spell, it doesnt look like a fireball but it was as close as i can get it hope it helps
