Actions
Bite: Melee Weapon Attack: Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage plus 3 (1d6) acid damage.
Suppose the target is large or the smaller creature, it is grappled i.e, (escape DC 13). Unless until this grapple will end then the ankheg can be able to bite only the grappled creature and also has the advantage on the attack rolls to do so.
Acid Spray (Recharge 6):
In a 30 ft long and 5ft wide line the ankheg will spit the acid and provided that it has no creature grappled. But each and every creature in that specific line should make a DC 13 Dexterity Saving throw and also taking the acid damage 10 (3d6) on a failed save, or else half as much damage on a successful save too.
