Ghast¶
These creatures are so like ghouls as to be physically indistinguishable from them, and they are usually found only with a pack of ghouls. When a pack of ghouls and ghasts attacks it will quickly become evident that ghasts are present, for they exude a carrion stench.
It has also been said that Ghasts are far more cunning than their lesser
counterparts, although it has been some time since I’ve gotten close
enough to find out.

Although Volo may be too skittish to go near these beasts, I can confirm both
their intelligence and their danger. Keep a weather eye and a careful distance
when ghasts are about.
