Yagluth is much tankier now than he was. I used Frostner and had mistlands-level food and he still took about 15 minutes or so to kill, and that was me standing in the flames wailing on him whenever I got the chance.

I think Yagluth's damage output is fine - the meteors really hurt but are easily avoided, and everything else fire resistance minimizes - but he has a lot of HP/armor and it seems like he attacks constantly.

I should try again and see if I can circle behind him more, that seems to be the way to spend more time attacking than running and hiding from his beam/meteor attacks, lol.
