Acid Jet: The Esid-Daanav spews acid from its mouth glands in a 45x5 foot line, reducing Armor by 1 Grade.

Successful saves only take half damage. Roll a 1d6. The ability recharges when that 1d6 lands on a 5 or a 6.

Bonus Actions

Breach: The Esid-Daanav breaches the ground and deals 1d6 unmitigated bludgeoning damage in all adjacent spaces. Targets in the adjacent spaces must make a Dexterity saving throw against a DC of 12 or be pushed back and take damage.
Burrow: The Esid-Daanav burrows into the ground and collapses the tunnel behind itself without provoking opportunity attacks. This pushes back all targets in the vicinity and leaves a mound behind. While underground, the creature has the benefit of being obscured and has full cover.
