In durlags tower, i have the mallet head and handle but i dont know where the anvil is, i do know where the gong is so help me.

when you first came into the main room down one floor from the ground level you started finding rooms on the npc's left hand side or your screens right side. go to the top of the screen or the NPC's right hand side when they first came into the room and look for small rooms. at the top of the screen you will find a small room behind hidden doors with the anvil in it but watch out for the traps.
