You can attack twice, instead of once, whenever you take the Attack action on your turn.

You can sense the presence of celestials, fiends, and undead within 60 feet of you, and you can detect consecrated or desecrated places and objects. You can use this feature a number of times equal to 1 plus your Charisma modifier, regaining expended uses after a long rest.

You have a pool of healing power that replenishes when you finish a long rest. You can restore a total number of hit points equal to 25, and you can spend that pool in any combination on creatures you touch.
