Concentration

Abilities with the "Concentration" Penalty (or "Concentration Abilities") impose one stack of Concentrating when they take effect and remove one stack of Concentrating when that effect ends.

All Focus Saves and Concentration Ability Tests have one Disadvantage for each stack of Concentrating that you have. If you Fail such a Test, all active Concentration Ability effects end.

If ever a Component of a Concentration Ability is affected, you must make a Focus Save.
