Necromancer mask
make another necro to get the mask and transmute the mask onto the stats of a white head armor piece. then you can put it into your bank and your old necro can take it and wear it, transmuting it again as you like. you just need a spare character slot. then delete the new necro. job done.
Mimizu Heavy Industries [Doll] – Underworld
roll a new necro (you can delete it later) and then take the mask and tansmute to white item. The mask is not soulbound after this so you can take it and transmute it onto anything else for any cloth wearing character.
