Loki's Camp

I've just come back after a year long break or so and found a load of new stuff in the game, which is very cool.

I've found some legacy amulet pieces and those seem interesting, got a few tips as to what they do.

I've also encountered a new spell, Freezing, and gotten some Anti-freeze cups.  Wondering if anyone knows how this works and if there is a protection from it from the witch?  Thus far been able to overcome enemies with freezing, but I got frozen once and it seemed to work like paralyze where it shortly wore off.  

I think the best protection is protection from magic which you can find in the Hallows. Other than that I think you can drink it, anti-freezing, after your frozen.
