Unshaken

Reactive Teamwork Talent. Costs 1 Reaction Point when the trigger happens, with your bonded partner within Close range. The RP cost never changes at any tier.

Trigger: Your bonded partner is about to save against an effect (Charm, Mental, Emotion, or an ordinary attempt at manipulation) meant specifically to drive a wedge between the two of you.

Tier 1 (Level 1): Grant them 1 level of Advantage on that save.

Tier 2 (Level 5): As Tier 1, but you grant 2 levels of Advantage.

Tier 3 (Level 9): As Tier 2. You may also spend 1 Strain as part of the reaction to cancel 1 level of Disadvantage they face on that save.

Tier 4 (Level 13): As Tier 3, but you may instead spend 2 Strain to cancel up to 2 levels of Disadvantage. And even if your partner fails the save, the effect can never make them act directly against you; it can still affect them in every other way.
