I had an idea for a behavior edit on Ballos's first form. Do you think you could help?
Basically, it's inspired by an interesting glitch that occurred when I first tried to edit the npc.tbl using Cave Editor. When I fought Ballos, his stomp attack would send him through the ground. After doing the attack again while falling into nothingness, he would rocket up out of the ground at you (the behavior he displays if you're above him when he tries to stomp). I actually found it to be quite an interesting idea, but I haven't got the slightest clue how to implement it.
