Is there a way of being able to use multiple tail or even amulet slots and have the items actually show??

No. You can only see one amulet, two rings and one tail slot item visible as a model on the character.

Pissed

Thanks for the reply though.

Unless you combine the items into a single NIF file -- though that would make them a single item (so technically not multiple items) but you could at least seem them both on your character.

What people should mod in, is tail armor! Armored tails for the beast races ^^
