Component
Some Abilities will list Components needed by the Ability. Components can be generic things like “hands” or “standing,” or a specific type of point you must spend from one of the Point Banks on your Character Sheet (Note: Your Shield, Health, and Vitality are Point Banks. You may also have Point Banks unique to your Class or Constitution.) If points are listed, then you must spend that many points before the Ability can be rolled for.
If you are lacking a Component when it comes time to roll the Ability's Skill Test, you will receive a Disadvantage for every missing Component. Note that that means that Abilities with an Ability Time greater than one Beat will only need to meet their Components when spending the final Beat needed to fulfill the Ability's Ability Time. This includes Slow Actions.
Unlike Requirements, Components also need to remain unaffected for the entire Effect Duration as well. If a Component is interrupted at any point during your Effect Duration, you will need to re-roll the Ability's Skill Test and get a Mixed Score or the Ability's effects will immediately end. This Test is performed for each Component that was interrupted.
If one of the Components is a Point Bank, that Point Bank gains a soft lock (often tracked with a small token.) If that Point Bank changes, up or down, that change counts as an interruption of the Component.
It is worth noting that the Component 'Concentration' adds a second layer of difficulty. Concentration imposes a Disadvantage to an Ability's initial Ability Skill Tests for each other active Concentration Ability.
