spewster is a swamp monster. he has eaten the gate key,so you cannot get out. ranged or magic attacks are not recomended, because he can abosrb them and spit them back at you.(yes, lasers also) he is also immune to elements, but he is very messy, and can spread poisonous glop on you, and can heal constantly. if something were to clean him up, then he would be easier to defeat.
