I haven't really been playing D:OS much at all since I posted the videos, I've been busy with other things. The news of the upcoming EE has encouraged me to try to finish off this playthrough, though.

I fought Boreas today. Since I had 3 physical attackers to only one mage - and not that many direct damage spells for her either, I opted to ignore the statues completely and just fight him with physical damage. My Inquisitor ignored Boreas completely, and focused on buffing and healing my teammates. With 16 Int, a lot of my cooldowns were only 1 turn, so I could drop Elemental Absorption on someone each turn, and often I had the AP to do more.

It turned out that the center area of the room still received the elemental surface treatment, but it couldn't be helped. I was often able to use the edges of the area to avoid the worst of the surfaces. Boreas got off one complete cycle of the elementals plus a bonus ice round before I took him out.
