Bahamut's Left Wing

This platinum and steel pauldron magically fashions itself to an existing suit of armor.  It is a carved representation of the Platinum Dragon, given and used only by Bahamut's devout.  It stores one use of the attuned user's class ability or utility (i.e a Fighter's Action Surge or Second Wind, a Barbarian's Rage, or a Paladin's Channel Divinity).  Only one may be stored and used at a time, and it can only be charged during a short or long rest.  Once used, the charge cannot be used again until the following dawn,
