Petrified

From NWNWiki

A petrified character has been turned to stone and is considered unconscious. If a petrified character cracks or breaks, but the broken pieces are joined with the body as he returns to flesh, he is unharmed. If the character's petrified body is incomplete when it returns to flesh, the body is likewise incomplete and there is some amount of permanent hit point loss and/or debilitation. Though a petrified creature has the visual appearance of standing up, it is in fact still susceptible to prone conditions such as knockdown.
