Aura of Mythic Madness (Su)

Any sane being within 30 feet of a conscious mythic seugathi must make a DC 21 Will save each round or become confused (as per mythic confusion) for 1 round.

A creature that fails 5 saves in a row becomes permanently insane, as per the insanity spell but with a continuous mythic confusion effect. In addition, if a mythic seugathi expends one use of its mythic power as a swift action, any nonmythic creature within its aura that is immune to confusion loses that immunity for 1 minute. A mythic seugathi can suppress or activate this aura as a free action. This is a mind-affecting effect. The save DC is Charisma-based.

Breath Weapon (Su)

A mythic seugathi can use its breath weapon once every 1d4+1 rounds to create a 30-foot cone of crimson gas. Those caught in the area of the gas are exposed to the mythic seugathi’s poison. If a mythic seugathi expends one use of its mythic power as a free action when using its breath weapon, not only must creatures caught in the area make two saving throws and take the lower result, those that fail their save are sickened in addition to the other effects of the poison.

Confusion Command (Su)

As an immediate action, a seugathi can issue a telepathic command to a confused creature within 30 feet. This allows the seugathi to pick a result from the relevant confusion behavior table, rather than the confused creature rolling randomly for its actions that round.

Infectious Insanity (Su)

If a mythic seugathi expends one use of its mythic power as a free action when using its confusion command ability to cause a confused creature to babble incoherently, any sane being within 30 feet of the confused creature must make a DC 21 Will save or become confused for 1 round. This is a mind-affecting effect. The save DC is Charismabased.

Item Use (Ex)

A seugathi can utilize spell trigger devices as if it were a spellcaster of the appropriate class. As a free action by touch, it can identify all spell trigger properties an item has.

Use Magic Device is a class skill for seugathis.

Mythic Spell-Like Abilities (Su)

Three times per day a mythic seugathi may cast the mythic spell version of any of its corresponding spell-like abilities. A mythic seugathi must expend the same amount of mythic power that would normally be required to cast a mythic spell, treating its mythic rank as its mythic tier for the purpose of qualifying to use augmented versions of mythic spells.

Poison (Ex)

Bite—injury; save Fort DC 19; frequency 1/round for 6 rounds; effect 1d2 Wis and deafness; cure 2 consecutive saves.

Deafness persists as long as the ability damage caused by the poison lasts. The save DC is Constitution-based.


Environment any underground
Organization single, pair, or expedition (1 mythic seugathi and 3–8 seugathis)
Treasure double (+1 rapier, wand of scorching ray [CL 7th, 1d20+30 charges])

This worm-like monster has a hideous face of eyes and hooked jaws. It wields a wand and a sword in its twin tentacle tails.

Seugathi are spawned by the hundreds by a single neothelid that has performed rituals to impregnate itself. As part of the strange process of being spawned in such rituals, the seugathi assimilates an extensive list of missions from its parent—once the seugathi completes these missions, it perishes. No single seugathi knows the purpose of these commands, but they trust that their neothelid masters have a reason for sending them on these diverse and usually cruel missions. A seugathi is 14 feet long and weighs 650 pounds.
