Watch Your Step

Level 1

When an ally within 60 feet must succeed at a Reflex save to avoid a harmful effect, as a reaction before your ally attempts the saving throw, you can grant the ally a +2 bonus to that saving throw.

At 6th level, you can spend 1 Resolve Point to have the ally roll twice on the saving throw and take the better result. Both of those rolls benefit from the +2 bonus provided by this ability.
