I am tier 12 and am wondering what weapons I would need to vanquish this opponent? Any advice would be great. Do people lend weapons on this site? I have some expensive weapons that I could put up as collateral. Thank, Judy

He does a bunch of wind and ice damage, so Swash and ISS will help mitigate that. I think he also did a bunch of dark and earth (?) so you might be able to sub in Maniacal Essence or The Ether. Swash and ISS should be affordable if you don't already have them. He's pretty tough even at T12 though. His curses are aggravating.
