Actually the diversity is one thing I’ve come to embrace. When I was fighting Renalla, I was running in circles, trying to avoid her attacks, avoid her summons, throwing rock sling when I could, and I just could not take her out. I tried running clockwise, counter clockwise, running in on occasion to hit her with my moonveil, etc. Then someone here, I believe, mentioned trying to dual wield katanas and power stance so I replaced my meteorite staff with another katana (can’t remember which one) to go with my moonveil and closed in on her and hit her with power stance attacks. It worked surprisingly well and I took her out pretty easily. It then got through my thick head: relying on one approach simply won’t work in this game.
