An ankheg burrows with legs and mandibles. A burrowing ankheg usually does not make a usable tunnel, but can construct a tunnel; it burrows at half speed when it does so. It often digs a winding tunnel up to 40 feet below the surface in the rich soil of forests or farmlands. The tunnel is 5 feet tall and wide, and from 60 to 150 feet long ([1d10 + 5] × 10).

Their strengths lie in their ability to burrow underground to hide or surprise prey by spitting acid. Lets not forget their extremely hard shells! However, If they use their acid they can’t eat for 10 hours. Like most insect creatures, they’re weak to fire and are a bit on the dumb side when things get tough. Oh, but they hate the cold too. So, during the winter they hibernate.

Ankhegs are edible. They taste like a cross between cricket and lobster. They’re also great for making farmlands fertile! Even the most rocky shitty of places. So farmers may be able to use their remains to make soil fertile.

Combat

An ankheg usually lies 5 to 10 feet below the surface until its antennae detect the approach of prey. It then burrows up to attack.

Improved Grab

If the creature successfully grabs a victim, it will immediately retreat backwards into its tunnel.

Spit Acid

30-ft. line, once every 6 hours; damage 3d acid. An ankheg does not use this ability unless it is desperate or frustrated. It most often spits acid when reduced to fewer than half its full normal hit points or when it has not successfully grabbed an opponent.
