And I pull from the SRD. Bolded for emphasis. http://www.d20srd.org/srd/conditionSummary.htm<br/><br/>A character with 0 hit points, or one who has negative hit points but has become stable and conscious, is disabled. A disabled character may take a single move action or standard action each round (but not both, nor can she take full-round actions).<strong> She moves at half speed</strong>. Taking move actions doesn’t risk further injury, but performing any standard action (or any other action the game master deems strenuous, including some free actions such as casting a quickened spell) deals 1 point of damage after the completion of the act. Unless the action increased the disabled character’s hit points, she is now in negative hit points and dying.<br/><br/>EDIT: It is ambiguous. In the pages, it makes no mention of half movement, but in the glossary at the end of the book, it's written as above. That's... interesting.
