ghast

Gasts are kind like shades, there composed of dark magi, but instead thier species can grow in number, and light magi harms them instead, also they can wrap thier bodies around you like rubber super heros, and get this, they can't fall to thier deaths, seriously they cant, see that bit ant the bottom were the legs should be, well it always streches to remain in contact with the ground, and I don't mean the earth, I mean a floor, they are always attached ,the further the floor though the more they get streched out to remain in contact.
