Encountering one of these creatures in the Underworld can be a dangerous proposition; they know much about the world around them and the veils between planes, but those who raise its ire can quickly find themselves buried underneath stone. \n'b' Rakasa batu are generally 13 feet tall or larger, but can weigh between 300 and 6000 pounds.'
