Pakano (Level 12)

When a frost worm dies, it explodes in a 100-foot burst of searing cold blood. All creatures and objects in range take 10d8 cold damage (DC 29 basic Reflex save).

Pakano's allies are unaffected by his worm chill aura and Worm Trill, and his Freezing Blood affects random enemies instead of random creatures. His Death Throes, however, still affect all creatures and objects in a 100-foot burst.

5 feet. A creature that enters or begins its turn in the emanation takes 3d6 cold damage (DC 29 basic Reflex).

The frost worm emits a hypnotic trill. Each non-frost worm creature within 100 feet must attempt a DC 32 Will save. The effects of Worm Trill last for 1 round, but if the frost worm uses this ability again on subsequent rounds, it extends this duration by 1 round for any creature already affected.

Success The creature is unaffected and is immune to Worm Trill for 24 hours.

Failure The creature is Fascinated by the frost worm.

Critical Failure As failure, but the fascinated condition doesn't end if the frost worm uses hostile actions against the creature.

The frost worm exhales a blast of frost, dealing 13d6 cold damage to creatures in a 50-foot cone (DC 32 basic Reflex save).

It can't use Breath Weapon again for 1d4 rounds.
