Every monster in the whole game but the drop rate is only 0.75%. If you want it then I recommend going to SwordhavenUndead
(/join SwordhavenUndead) Then when you get there go left and to the second screen where there is four level 1 monsters and use a class that can target 3 or more enemies (Shaman,Evovled Shaman,Proto,Rusbucket,Enforcer,Dragonlord,Chaos Shaper) or just use ninja cause it kills 1 monster quickly. You just fight them until it drops a treasure chest and viola! THIS IS THE FASTEST WAY NOT THE ONLY WAY! (I figured this way out and i got a treasure chest in 5 minutes using the class that targets 3 monster or more, in my case Evolved Shaman)
from any monster you can get a treasure chest but it is hard to get from:matthijs schmidt
You Have to open Twilly"s treasure chest
57 prizes so far. **Keep in mind that you cannot choose the item you get from the chest**
Keep fighting monsters.
You can buy them from shops or get drops from monsters.
