I didn't notice that the first time I went through. A couple casts of Firewall level 3 didn't seem to do anything to them... (one cast took out the captive dragon elf there I couldn't target or hit directly).
Maybe those are walking armours that have not been completed yet?
Maybe they were suppose to be released when you took out the others in the room, or something, but it got cut back to one (I only saw one come out, anyway) when they were balancing the game?
I told the sisters I was the strongest, since you get more experience that way (I sided with the walking armour one first, then reloaded). Plus, it was nice to see them putting their differences aside to work together the last few minutes of their lives.
