That would seem like a good idea, but the max hit of Crumble Undead and Fire Bolt with chaos gauntlets is the same. And you cant use an elemental staff if you use a slayer staff. I think it is 4 airs and 1 earth for Crumble Undead, and 3 airs/4 fires for Fire Bolt. I think it would just depend on whether you have a large stock of earth runes or fire runes. Adding on to that: Fire Bolt gives more base xp than Crumble Undead. And I already said no irons. I'm not debating it, I don't like them and I'm not doing them. and if an ankou hits an 8 on me, I'll eat a peach.
