Beak Crunch [>] Requirements The deghuun has a creature grabbed with its tentacles; Effect The creature takes 4d8+17 piercing damage.

Sulfurous Plume [>>] (fire, poison) The deghuun vents caustic smog for 1d4 rounds. Any creature that ends its turn within 30 feet of the deghuun during this time takes 6d6 fire damage and is sickened 1 (DC 38 Fortitude save; the creature avoids the sickened condition on a critical success, or is sickened 2 on a critical failure). While sickened in this way, a creature takes a –2 status penalty to its saving throw against the deghuun's hallucination. Any creature that's in the smog is concealed and treats other creatures as concealed. Strong winds dissipate the smog.

Tentacle Assault [>] The deghuun makes three tentacle Strikes, each against a different creature within reach. These attacks count toward its multiple attack penalty as normal.
