What other accesories could I equip?
 

I counted the inventory slots around my armor slot in the inventory, and I counted 14 slots. I have 5 slots occupied so far: Eyes, head, costume, back, and pet.

Does anyone know what the other 9 are for? Especially the slot above the costume and in between the eyes and the head?

Weapon skin? not sure tho :cutielove:

I don't know. I know that some costumes have a top and a pants/skirt though. So that's another slot. Weapon skin would be one; though I haven't used one yet.
