Bahamut's Backhand

As an action, the cleric can call upon Bahamut to strike a creature within 30 feet with a powerful divine backhand. The creature must make a Wisdom saving throw, and on a failed save, a golden shimering draconic claw appears and slaps the target, it is stunned until the end of the cleric's next turn. In addition, the cleric can choose to deal radiant damage equal to 3d10 + their cleric level to the creature, but this damage cannot reduce the creature's hit points below 1 (bahamut doesnt like to kill).

Can be used again after 1 Day.

However, using this power comes at a cost. The cleric must also make a Constitution saving throw, and on a failed save, they become exhausted until the end of their next turn.
