I can't find any list of things that can come out of the boxes sold by the peddler who randomly appears in the dungeons, so I thought I'd start a thread for people to say what they've got.

Box Contents:
eggs
gold
essence
avatar items

bump to stop from being locked

Sometimes you get less gold than you paid, sometimes you get equipment, sometimes you get potions, and very occasionally you get a Sylesti egg.

I've gotten generator essences from these before. Very rare.

same here. recently i got a rare accessory from the level 25 one.. but i can't remember exactly what it was

I thought I saw another thread about treasure boxes somewhere but I can't seem to find it. anyways, I just got an epic faded relic of the evoker from a level 25 treasure box (2500 gold)
