Sona

Hurl a chunk of magnetic debris at the nearest target without one, dealing 300/450/999 magic damage and sticking it to them. If an enemy with debris dies, it passes to the nearest enemy without one.

Every 5 casts, instead rip off all debris dealing 120/180/999 magic damage, then crush all the debris onto the target, dealing 720/1100/9999 magic damage and briefly stunning them.
