Is Bernard possible on Honor mode?

I managed to flee from this fight but overall it feels like he just does way too much damage and takes none, I missed 8 or so attacks in the first round of combat immediately.

My party is level 5 and consists of an eldritch fighter, open hand monk, throwserker, and light cleric. I shut down the ads with sussur blossoms but that doesnt really matter because Bernard is by far the biggest threat.

I’m done most things in act 1 besides the hag grym and bernard. I had to flee from grym as well because I low rolled and one of my party members walked into lava.
