Here's a list of all the stuff in the pile o' curses, gifts, and crates. I totally stole this from SPUF:
http://forums.steampowered.com/forums/s ... ?t=2986459I'm most interested in the pile of curses as that's also what most of us get. Crates aren't worth opening unless you're a collector of "haunted" items.
It awards the player one of the 9 playable class' Voodoo-Cursed Souls (That make your class look like a Zombie) and sometimes an Eerie Crate or a Halloween Spell (see below). Any souls received have a chance to have the Haunted item quality. You also have a chance at getting one of the new hats and miscs in Uncraftable quality, none will be Haunted though (view Eerie crate list)
