Influence Effects

Enhance Faith All worshipers of Cthulhu, Father Dagon, or Mother Hydra within the area of influence have their effective spellcaster levels increased by 1 for the purpose of determining spell effects, and all save DCs from their spells are increased by 1 against non-worshipers of Cthulhu, Father Dagon, or Mother Hydra. Worshipers of these three entities gain a +4 bonus on all concentration checks.

Nucleus Crystal At stage 1, attempts to damage Father Dagon’s influence must be directed at the nucleus crystal at the center of the area’s influence. This influence’s effects function in a spread, so if the nucleus crystal is hidden inside a box, its influence radius is reduced to zero.

Mobile Influence Father Dagon’s influence is always centered on him, allowing him to wander as he will without being physically limited by the constraints of influence. Father Dagon can teleport beyond the range of his influence.

Special Abilities

Command Sea Monster (Su) Father Dagon can command sea monsters to do his bidding as a move action, using either speech or telepathy. This ability affects all aberrations, animals, dragons, native outsiders, and magical beasts with the aquatic subtype. A successful DC 27 Will save negates the effects of Father Dagon’s command; otherwise the targeted sea monster is affected by the command as if by a suggestion spell.

The commanded course of action can have a duration of up to 1 day. If Father Dagon issues a new command to a creature, the previous command is discarded. Once a creature succeeds at its save against this effect, it is immune to further commands from Father Dagon for 24 hours. This is a mind-affecting effect. The save DC is Charisma-based.

Mortal (Ex) Unlike most of the other entities associated with Elder influences, Father Dagon is mortal and can be killed. If slain, though, it’s typically only a matter of time before an equally powerful deep one rises to fill the vacancy left behind by Father Dagon.

Spells Father Dagon casts spells as an 18th-level sorcerer. He uses the cleric spell list.

Swift Bite (Ex) When Father Dagon makes a full-attack action, he can make two bite attacks.

Tail Sweep (Ex) Father Dagon can make a sweep with his tail as a standard action or as part of a full-attack action. When he does so, he affects a 15-foot cone. All creatures in this area must make a successful DC 29 Reflex save to avoid being stung by several of Father Dagon’s toxic tendrils. A creature that fails must make three separate DC 29 Fortitude saving throws to resist three different effects, as detailed below. All of the below effects are poison effects. The save DCs are Constitution-based.

Hallucinations: The first Fortitude save is to resist hallucination-inducing toxins. A failed save causes the target to become confused for 1d6 rounds. This is a mind-affecting effect.

Paralysis: The second Fortitude save is to resist being paralyzed. This effect is permanent, but at the start of a creature’s turn, a creature can attempt a new DC 29 Fortitude save as a free action to end the paralysis effect.

Poison: The third Fortitude save is against flesh-eating toxins. A failed save indicates the victim takes 1d4 points of Constitution drain and is staggered from pain for 1d3 rounds.

Father Dagon is the military, political, and religious leader of the deep one species. He is an extremely large, powerful, and old deep one—not a Great Old One. Other deep ones have achieved levels of power similar to his, but he is their foremost leader.

The deep one life cycle is such that they transform with age and size. Most feed enough to maintain near-human size, as this is convenient for normal activity. When they grow larger, they can undergo further transformations, as is the case with Father Dagon. He is no longer even vaguely humanoid, with flippers, a seal-like body, and a mass of sensory appendages for a tail. Other deep ones that have reached Father Dagon’s size do not have the same shape: a combination of rituals and mental discipline on Father Dagon’s part have been key to his development.

Father Dagon is often associated with Mother Hydra, as these two are the best-known elder deep ones to land-dwelling races, but they act independently. She controls other aspects of deep one society.

Cultural Import

The deep ones do not actually worship Father Dagon, but they honor him and allow his wisdom to guide them. Deep ones force their humanoid followers and half-humanoid hybrids to worship Father Dagon, however. Typically, the worship is channeled toward a magical statue or crystal, and through the item to Father Dagon himself. He uses this to enhance his physical supremacy and form, as well as to empower spells and ceremonies under the sea to further his plans. With assistance from his worshipers, Father Dagon can create massive waves to swamp boats at sea, or inundate shorelines. If he has enough preparation time, he can create a full-fledged tsunami to wipe out shoreline cities and nations. Fortunately, he is more often interested in protecting and guiding the deep ones, as well as aiding them in expanding their territory and influence.

Father Dagon has control over a number of undersea monsters created by Mother Hydra’s hybridization experiments, as well as other horrors such as shoggoths. He is incredibly intelligent and can cast a wide variety of spells to assist him in controlling and aiding his hordes of deep one minions.

Father Dagon in Combat

Father Dagon’s massive fangs are his main attack against similarly gigantic enemies. His far-sweeping tail is actually of invertebrate origin and is filled with toxins and stinging cells. Father Dagon can die like any other mortal being, but the deep ones can raise another entity of his power from their midst by simply feeding and channeling worship to him, so a new “Father Dagon” will soon arise.
