In the Ice Caves of Sorrow mission, after you have Evennia and are taking her to the ship, you see that large bunch of Mursaat. If you are dumb enough to try and fight them (like our group was, because they wouldn't move) you notice that they have a spell that makes you have
50 health degeneration. Unless I read it totally wrong and it's actually 5 health degeneration.
Does anyone know what the heck this skill is?
