The fight's okay, I got it down to half health with a level 7 novice using a sword I got off a greater wisp, just gotta dodge sometimes and make sure to block if necessary, I guess.
If you need something that's a bit of a cheat, the game is coded weirdly and most attacks scale with click speed way more than it first appears. I've got an autoclicker built into my mouse and using it triples my attack speed for some reason (minus with hammers.)
Other option is to farm all the other stuff and hope something good drops, but the RNG is pretty bad so IDK.
