Platinum Oath

Has 3 charges of Everlast:
As a reaction to taking damage, the scales of
Bahamut unfurl from the ring and cover the
user's entire body indefinitely, granting them
immunity to all damage and conditions.
However, while covered in platinum scales,
the user cannot take any action whatsoever -
leaving them rigidly frozen until they dispel
Everlast on a future initiative.
