So here is the thing with an ion disrupter. It has an AOE hitbox even when TRAVELING to the point. Which it something not a lot of people think about since the RPS and PLX doesnt have an AOE hitbox.
I dont know how you got an ion disruptor, but this is why it shouldnt really be spawned in casually. Imma +1 this as I know the pain first hand of the AOE Travel Effect. You know it has it now, and I doubt you'll make the same mistake twice.
