Im currently trying to farm Skeletron and so far it hasnt dropped anything. I get that the reward itself is access to the dungeon but after defeating it for the first time I'd like atleast one guaranteed item drop from it.

I'd take farming methods but besides getting the voodoo doll(which I already have) and making a new world and waiting for night, I dont think isnt a better method than sleeping until the clother respawns.
