Describe the bug
The potion ring items cannot be put in the offhand ring trinket slot (offhand/ring)

To Reproduce

1. Attempt to place potion rings in the offhand trinket slot
2. Potion rings currently cannot be placed there

Note: The offhand ring slot does not show at all unless another mod is installed that uses it, since this mod currently does not use it.

Expected behavior
Potion rings should be able to be placed in both ring trinket slots.
