Skull is the damage resist one? Time to change it! It'd function more like Orpheus Rig now. Players would no longer take damage from Vortex, and Cataclysm's self damaging traits sould be a 1-1 match with Blade Barrage since the two are always being compared. Damaging and defeating targets with Cataclysm grant super energy. Vortex blinds targets and grants allies invisibility while inside. Vortex also lasts significantly longer, but deals less damage per second as a result. (It would do the same damage, if not more, only over the course of 15 seconds instead) Take no self-damage from grenade abilities.
