Help plz got game tonight in a few hours.

[Throne12]

One of my players can't make it tonight so I'm doing a one shot with 15th level characters. These characters will be hero's there Regular characters will hear about later.

Any way there are 3 players a fighter champion GW fighter, a barbarian I think totem, and some weird triple MC melee build.
1. The fighter want some kind of cold damage. So I was thinking a magical armor that allows him to cast armor of Agath's. What else should this have?
2. Barbarian I was thinking of some boots that alolws to cast earthquake and another small ability
3. The triple MC wasn't a ring of enlarging .
