The signet ring has a definite magical pattern, which is apparently a [[ritual focus]].<br/>
The focus is currently unattuned.

This gets linked to spellbooks, not mana types. Cannot be used for other spellbooks of the same mana type.

When used to cast Absolution:
You focus your magical senses on a brushed gold signet ring cradling an aurora tourmaline.
The signet ring has a definite magical pattern, which is apparently a ritual focus.
The focus is attuned to the Body Purification spellbook.
While the magical nature of the focus is clear enough, you will need to study it more carefully to recollect how they function.
