Channel Divinity: Sentinel's Service

Starting at 2nd level, you can use your Channel Divinity to harness sunlight, banishing darkness and protecting your allies.

As an action, you present your holy symbol, and any magical darkness within 30 feet of you is dispelled. Additionally, you may imbue a number of allies equal to half your level + your wisdom modifier within 30ft with protective energy until the end of your next turn. All damage taken by these allies is redirected to you and you have resistance against this damage. Your speed becomes zero until the beginning of your next turn, and you may not take reactions.
