Unconscious

Unconscious

You are no longer capable of taking actions, and pass out. You fall Prone and become Helpless. Unconsciousness results from having your current hit points drop below zero, but not drop so low that you are dead (a character is dead when their current hit points are less than or equal to their Character Level + CON score (not modifier)). Unconscious includes all the penalties of Helpless and Prone, including susceptibility to coup-de-grace attacks. Unconscious characters cannot take any actions except some free actions (such as saving throws), though some free actions are simply not possible (such as speaking). The GM is the final arbiter of which free actions are permitted.

Any conditions you were suffering under, and any bonuses or buffs you have applied to you (as from spells) typically remain in effect while you are unconscious (though they may not provide any benefit until you regain consciousness, as with fast healing). Any time limit on the conditions or buffs (i.e. 'until the end of your next turn', etc.) still tick down while you are unconscious.

Generally, monsters die upon reaching negative hit points, rather than becoming unconscious. If a monster needs to fall unconscious for story reasons, they generally just stop accumulating damage once they reach 0 hit points.
