Well, the setting has Highlander-inspired Beholders and Anne Rice-inspired wig-wearing Mindflayers*, so I would not consider ridiculousness much of a problem.

But it's a good start, especially on the weapon, though I'd suggest perhaps making the handle of the polearm/drill/chainsaw look something like a rifle, and adding some barbs to the drills to allow for a greater "grip" as they pass by. I'm thinking of them as wallcutting/digging tools as well as weapons, so you know where I'm coming from.

*I haven't written those up, but they're coming, I swear!
