I've had one of the skulls (wolf I think?) from several nightmare invasions ago, and I still haven't been able to get rid of it. That and a wolf monster head.
(Hopefully) Useful CO Resources: HeroCreator (character planner), Cosmic Timers/Alert Checklist, Blood Moon Map, Anniversary Cat Map, and more (eventually, anyway).

If you do this and still want a skull head you can use partial and go no head and wear a headwear skull.
Allowing this would make it so you could use faces in the skull, more customization options
My super cool CC build and how to use it.
