====== Open ======

A creature with the Open status has its defences down or bypassed.

A creature is Open if any of the following are true:
  * It has not yet had a turn in the current encounter;
  * It is [[nexusframe:conditions:Asleep]], [[nexusframe:conditions:Blinded]] or [[nexusframe:conditions:Stunned]];
  * The attacker is [[nexusframe:conditions:Hidden]];
  * Any other rule explicitly states that the creature is Open.

Open expires when the condition causing it is no longer true.
