Just noticed something today regarding the Cryogenic Stasis. It seems that both the Shackles of Pain and Guardian Angel are still capable of damaging and killing a character with this status. I'm pretty sure that Retribution damage and certain special statuses will ignore the status as well.
I can't say whether this is intended or not but the skill does states "immune to ALL damage".
Also, when you enter a conversation with certain NPCs (in example the Doctor in Arx), you can do two different serious abuses:
1) You can teleport this NPC at will without breaking the conversation or aggroing him. And as long as you teleport the other side of the conversation as well (so when you end the conversation they are still in conversation range), it is possible to start the combat in any location. I managed to move my character and the Doctor to Linder Kemm and got all the paladins to my side, which made the combat somewhat trivial.
2) You can aggro the other enemies in the Doctors house without aggroing the Doctor himself. Obviously you must deal with them without one of your characters since he is in conversation. After this, only the Doctor will be left to deal with.
