Desperate Prayer

It's always darkest before the dawn and the sharpest grief fuels the sincerest prayers. You gain the following benefits:

• Increase your Wisdom score by 1, to a maximum of 20.
• When a creature within 60 feet of you is reduced to 0 hit points but not killed outright, you can utter a desperate prayer by using your reaction. The target regains hit points equal to your proficiency bonus + your Wisdom modifier. If the creature reduced to 0 hit points is yourself, you don't need to use a reaction to utter the prayer. Once you do this, you cannot again until you finish a long rest.
