I know it's not a big deal because the number of characters who can cast this spell can be counted on one hand, but as one of them I think Hellball's casting range is a bit too short. In fact, its maximum casting range is equal to its radius, which means if you cast the spell from as far away as you can and don't move it will still hit you. You have to actively run away from it after casting, and so does everyone in front of you. It'd be a nice 'QoL' change for the next update if you could boost the cast range so there's less risk of accidental party-kill/suicide. Thank you!
That would require alterations to the haks. I plan to address a number of epic spell related things in a secondary smaller update. I'll add that to the list.
