Create a duplicate of a Beast or Humanoid with half the creature's HP and no ability to learn or change. The simulacrum is friendly and obeys your instructions. It lacks the ability to cast spells requiring material components of a cost greater than what it carries. If it dies, it can't be resurrected (but you can create a new one). Requires powdered ruby worth 1,500 GP plus snow/ice equal to the creature's size (consumed).

Material: snow or ice in quantities sufficient to make a life-size copy of the target, plus ruby dust worth 1,500 gp, consumed
