I just wanna comment on how you could make clemency both a ogcd and gcd (might sound weird on paper)

Lets say you reworked oath so it had no ties to shelltron/Intervention, I'm guessing having 50 oath (or something) could proc clemency to become a OCD, Cost no Mp and be instant cast this would even be a "decent alternative" against outright removing current clemency.

I don't really think clemency should be a oath gauge thing either way just food for thought.
