Can someone help me with this? i thought it was simple to do this, unless im not just trying x_x, +rep will be given

Although chain lightning looks like an "instant" cast (since lightning is an instantenous effect), if I recall correctly it actually uses a "fast" projectile, which means you'll need a damage detection engine to register when units get hit by the ability, and then check if they have a buff (does chain lightning even apply a buff?)

Since you're using GUI I recommend Bribe's Damage Detection system

A default Chain Lightning is hard to detect.

I think you should resort to build your own custom bouncing-chain system.
