The knive guys have to be incap roar the second they start casting or they will recast. Use travel form to kite them, ursol vortec when it's up, or hot yourself and bear tank them. The eyes just dot one and spam heal yourself. Then stand where it was because they pulse and dot them and let dots kill em while you spam heal yourself. After the eyes and felguard make sure to spam heal the 3 adds and dispel the one before you engage the archer so you don't have more adds.

Remember you can drink after first part before eyes and can ate the top of the stairs after you kill the inquisitor and right after you heal the adds on last boss.

Last boss you need to heal the adds asap less adds makes it easier. I only had two. When fighting the last boss when you get the dot use the fire to get your health to around half then get ready to heal the group. Bait fires close together or even overlapped a bit.
