Choked

1 Stack: Your speech is weak or faltering. You have Disadvantage on Spell Abilities with a #Chants Component.
2 Stacks: You cannot breathe. At the end of your Turn, You must Pass an Athletics Test or suffer 1 True Damage. If that Damage would cause a Wound, you instead gain a stack of Unconscious.

A creature can use a Free Action to hold their breath, provided they have no stacks of Choked. As a result:

• The creature gains a Persistent Stack of Choked which becomes Fleeting when they next breathe air.

• The creature has an Immunity against gaining new stacks of Choked.

• The creature can hold their breath for a number of Turns equal to 5 plus their Athletics Skill.
• The creature can stop holding their breath as a Free Action. Speaking or casting Spells that have a #Chants Component also count as ending holding your breath.
