A Glitch Castle is a place where the King and Queen glitches live. This place is surrounded by guards and some pretty cool items. Some items you can get are: Crown, wizard hat/robe, magic scrolls, stim packs, vantity items, etc. Glitch Castles do have some rare items in them. Furthermore, there are hostile guards guarding the premises and they do a big load of damage if all of them attack you at once. Every Glitch castle has a Glitch King.
