Your resolute fortitude allows you to hinder your foes and protect your allies using the following tactics.
Block
As a Bonus Action, you can choose one ally you can see. Until the start of your next turn, the ally's AC equals your AC if it is lower than that while the ally is within 5 feet of you. This effect ends early if you or the ally have the Incapacitated condition.
Challenge
As a Bonus Action, you can goad an enemy that can see or hear you into attacking you. Until the start of your next turn, the enemy has Disadvantage on attack rolls against creatures other than you while it is within 5 feet of you. This effect ends early if you have the Incapacitated condition.
Grasp
As a Bonus Action, you can block the retreat of foes within a 5-foot Emanation originating from you until the start of your next turn. A creature within the Emanation can't willingly move further away from you unless it first takes the Disengage action. The Emanation ends early if you have the Incapacitated condition.
