Action: Sustain Action | ◈

Many Abilities require Concentration⚙️, which is automatic. Some, however, have extra or strengthened effects when you Concentrate.
When you use this action, choose one of your abilities with the Concentration Trait. If it can be Augmented via sustaining, you activate that augmentation effect.
Sustaining an ability for longer 10 minutes (100 rounds or 1 Swift Rest) ends the abiltiy and gives you 2 levels of Exhaustion, as per the Exhaustion condition. This cannot make you go beyond 9 levels (i.e., it cannot kill you). The Sustained effect ends when you lose concentration.
Under normal circumstances, you cannot Sustain an ability if you are Exhausted or Wounded.
