I was looking at the spreadsheet and it says that Ethereal Urn is the 4th best trinket for BoS Frost. Why?
I'm trying to decide between an 880 Drained Mana Crystal (1712 STR/1096 HST), an 880 Unstable Archanocrystal (913 CRIT/HST/VERS/MAS), 900 Draught of Souls or the Ethereal Urn with a socket.
Seems to me that the Drained Mana Crystal+Unstable Archanocrystal is the way to go.
