Mobs have so much HP now, I don't think they're meant to be killed with spells any more.
Seems GK is now mostly Melee/bow based.
I've been leveling with the new West Haunted House mods with lightning walls for the past month. It WAS working until Maroku disabled Lightning Walls, even though he said "It's 100% not the lightning walls that is causing the crashes". Then why disable them. O_O
