A creature slain by the boiúna is reincarnated 24 hours later as an ordinary river snake with no recollection of their former life. Their former body (but not their gear) dissolves into mud. Once they are reincarnated, they cannot be returned to life by raise dead or resurrection, though reincarnate or wish can bring them back in their original form even if their body is not present by simply touching the body of water where they were slain, or the body of the boiúna, or the snake they became when reborn.
