Temp powers gained from the first mission include a nictus cone attack, a nictus teleport power, and a nictus auto res power.
The teleport is awesome, my favorite temp travel power. The auto res I havent had an opportunity to use, I'm a bit scared to, though. Don't want to go down in the middle of a bunch of nasties then pop back up just to go down again.
The temp powers are as stated before but the self res is actually an automatic resistance. These powers dissapear immediately after the nictus is extracted in the second part of the mission, fun to use though!
