Yeah, that leve was kinda brutal. But I was able to pull off whichever difficulty had rank 25 skeletons duos as a rank 18-19 gladiator. Guard, sacrifice, stoneskin, second wind, rampart, and shockspikes allowed me to barely survive, though.
But you know what still sucks? 1000 needles from a rank 20 cactaur... Why the hell is this ability still being used by low rank cactaurs? The leve requested me to kill 10 of them, and the last 3 attacked as a group. Surely one of them was going to bust out the needles.
