When a friendly creature within 30 feet of you take the Attack action as a reaction, the creature gains an additional reaction before the start of its next turn.
Any creature affected by your Bastion feature also can’t take the Move action more than once on each turn.
Whenever a friendly creature within 30 feet of you makes a saving throw, you can take a reaction to make the saving throw and allow the friendly creature to use your roll total in place of its roll total, but only before you or the friendly creature know the result of the saving throw.
