Hello, I'm a couple of weeks new to this game. Yesterday and today I was trying to kill Zolla and kept dying(Normal difficulty). My characters are mainly 4 and 5. So I tried something I haven't done at all in the game so far and that is run after I beat the easiest ogre.
After I did that, the most powerful of the 3, the druid ogre, reset but Zolla stayed out in the hallway. While running, 3 of my characters died however they revived(lack of the correct word) and I was able to go into combat with just Zolla out in the hallway without the druid interfering. Later on after killing Zoll
