Hornetaur

A Vespoid-like monster with a thicker shell. Easily damaged, there are rarely any usable materials left to harvest from them once killed. But if you could sap their Health gradually...
An insect that lives in places like the Jungle and the Great Forest. It yields valuable materials, but when killed with weapon attacks it often cannot be carved. If you are after its materials, it is best to poison it with a Poison Smoke Bomb or a weapon's added effect before killing it.
