Concentrating

Concentrating is always a Persistent Condition.

Abilities with a Test that involves "Concentration" (or "Concentration Abilities") impose one stack of Concentrating when they take effect and remove one stack of Concentrating when that Ability or its effects end.

For each stack of Concentrating that you have, you will gain a Disadvantage on Ability Tests that involve Concentration. If you fail a Concentration Ability Test, all active Concentration Abilities will end. When you Fail such an Ability Test, the Ability that caused you to lose Concentration may still take effect if it's description says that it does. In such cases, you will then gain a stack of Concentrating again for the active spell.

While you have stacks of Concentrating, if you take Damage, then you will need to make a Tuning Save. This Tuning Save will have a Disadvantage for each stack of Concentrating that you have. If you Fail the Tuning Save, all active Concentration Ability effects end.
