The Wand
The first thing you will need to do is obtain Icy Wand of Beltron. This is a quested item in Valdeholm which will be the key to your success once you're inside Frostcrypt. You must speak to Voodek in The Hidden Forest to get to Valdehom. Once you're in the zone, there are several NPC at the zone in, Renegade Kryol is who you must talk to for the wand. He then wants you to collect a few items for him.
#1 = Icy Cystal Shards
#2 = Silk Spinners Toxic Venom
#3 = Hardened Icy Rod
#4 = Zerakt's Research Notes
When you take all 4 items back to Renegade Kryol you will then obtain your Icy Wand of Beltron.
