Exalt

Your champion's reaction exalts nearby allies, allowing them to benefit as well.

Paladin:

When you use Retributive Strike, each ally within 15 feet of you with the target in their melee reach can spend a reaction to Strike the target with a -5 penalty.

Redeemer

You protect multiple allies. You can apply the resistance granted by Glimpse of Redemption to yourself and all allies within 15 feet of you, including the triggering ally, except the resistance is reduced by 2 for all.

Liberator

You can help your whole group get into position. When you use Liberating Step, if your ally doesn't attempt to break free of an effect, you and all allies within 15 feet can Step, in addition to the triggering ally.
