  When you cast this spell, you can assume the exact form of a deceased Small or Medium creature of the Humanoid type. Your voice changes to match that of the form you assume. If the form you assume has any of the following abilities, you gain the listed ability: Darkvision 60 feet, Low-Light Vision, Scent, and Swim 30 feet.
  Small creature: If the form you take is that of a Small humanoid, you gain a +2 Size Modifier to your Dexterity.
  Medium creature: If the form you take is that of a Medium humanoid, you gain a +2 Size Modifier to your Strength.
  The creature whose form you assume must be Dead and you must have access to its fresh corpse (either Dead less than 24 hours, or preserved via Gentle Repose or similar effect). Any attempt to copy the form of a living creature causes the spell to fail.
  You do not have access to the assumed form's abilities, memories, mannerisms, or speech patterns. The spell grants a +10 bonus on Disguise checks to appear as the imitated creature. If the assumed creature is returned to life while this spell is active, assume appearance immediately ends.
