A Goblin Wizard's(Permafrost) loot table/chance
 

According to the wiki(http://wiki.project1999.com/A_goblin_wizard_(Permafrost)) the Heart of Frost should be an ultra rare drop(maybe incorrect i guess?) but it seems to drop around 40%-50% of the time.

Whereas the Permafrost Snowball is listed as Rare and i guess the drop chance is about right, if i ever get one to drop :p

This has been observed by at least 1 other Shaman i know.

The wiki isnt right.
