World of Talamh
Poison Rare [If used in an enchantment, the enchantment takes on the abjuration school of magic's properties.]
When applied to a weapon, this powder sticks to it, and on the next 1d6 successful hits, will cause your weapon to deal an additional 1d6 cold damage. Additionally, this may be used when enchanting to cause resistance to cold damage, and no negative effects from the cold, so long as it doesn't drop below -40 Fahrenheit.
