---

Legendary Actions

Oceanus can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Oceanus regains spent legendary actions at the start of his turn.

• Lash of the Deep (Costs 2 Actions): Oceanus strikes with a massive wave or tendril of water, dealing 40 (6d10 + 10) bludgeoning damage to one target within 60 ft.
• Crashing Wave (Costs 3 Actions): Oceanus summons a wave to crash down on his enemies. Each creature within a 60-ft. cone must make a DC 29 Strength saving throw or be knocked prone and take 80 (16d10) bludgeoning damage. Half as much damage on a successful save.
• Flood the Land (Costs 3 Actions): Oceanus raises the tide, causing a 120-foot radius of land to flood with water. All creatures within the area must make a DC 30 Dexterity saving throw or be restrained and submerged, taking 60 (12d10) cold damage on a failed save, or half as much on a success. The water stays in place for 1 minute.

---

Regional Effects

The region surrounding Oceanus’ lair, usually the ocean depths or a hidden underwater realm, is affected by his presence. These effects last for 1d10 days after he leaves.

• Tidal Shifts: The tides are unpredictable and dangerous. Ships in the area suffer disadvantage on navigation checks and must make a DC 25 Dexterity saving throw to avoid being capsized by sudden waves.
• Storms of the Deep: A violent storm constantly rages within 100 miles of his lair, with fierce winds, torrential rain, and violent lightning. All creatures within the area suffer disadvantage on attack rolls.
• Abyssal Water: All water within 60 miles of his lair becomes imbued with Oceanus’ energy, allowing creatures to breathe underwater and making them immune to cold damage. Non-water creatures suffer disadvantage on saving throws against cold damage within this area.

---

Actions

---

Personality and Motivations

Oceanus is a mighty and enigmatic deity, both protective and vengeful. His connection to the seas grants him dominion over the world’s oceans, and his anger can bring devastating floods and storms. He values harmony between nature and civilization, but those who disrupt the balance of the natural world are his enemies. Oceanus seeks to preserve the purity of the oceans, protect aquatic life, and maintain his role as one of the oldest and most powerful deities. His long-standing rivalry with other Titans, gods, and mortal adventurers is as legendary as the sea itself.

---

Lore and Role in the World

Oceanus is one of the oldest and most powerful deities of the primordial pantheon, ruling over the vastness of the oceans and the primordial chaos that existed before time itself. As the father of all water, his domain stretches beyond the physical oceans to encompass all waters in the world, from rivers and lakes to rain and mist. He is a figure of ancient power, deeply connected to the balance of life and death and the perpetual cycle of water’s return.

Oceanus’ motivations are tied to maintaining the equilibrium of the world. Though he may seem distant and impassive, he seeks to maintain the constant flow of water that sustains all life. He is revered as the source of nourishment, but also feared for his ability to bring destruction through floods and storms.

Though he is a titan, Oceanus has alliances with various gods of the sea, nature, and wisdom, but he is also deeply antagonistic to deities who disrupt the natural flow, such as those who seek to exploit the seas or control water for personal gain.

---

Treasure: Oceanus guards many treasures in his underwater domain, including rare coral reefs, sacred relics from the ancient world, and portions of his own divine essence.

Oceanus is the world-ocean the enormous river that once encircled the world. This world-ocean was ruled by the Titan that shares its name Oceanus, a son of Uranus and Gaia. Having the upper body of a muscular man with a long beard and horns  and the lower torso of a serpent.

Oceanus originally represents the stranger more  waters of the Atlantic Ocean, while the newcomer of a later generation, Poseidon, rules over the Mediterranean.

Oceanus’ consort is his sister Tethys, and from their union came the ocean nymphs, also known as the three-thousand Oceanids, and all the rivers of the world, fountains, and lakes. From Cronus, of the race of Titans, the Olympian gods have their birth, and Hera mentions her intended journey “to the ends of the generous earth on a visit to Okeanos, whence the gods have risen, and Tethys our mother who brought me up kindly in their own house.”

In the war between the Titans and the Olympians, or Titanomachy, Oceanus, along with Prometheus and Themis, did not take the side of his fellow Titans against the Olympians, but instead withdrew from the conflict. Oceanus also refused to side with Cronus in the latter’s revolt against their father, Uranus.

The rich iconography of Achilles‘ shield, which was fashioned by Hephaestus, is enclosed, by the Ocean.

“Then, running round the shield-rim, triple-ply,
he pictured all the might of the Ocean stream.”

When Odysseus and Nestor walk together along the shore of the sounding sea their prayers are addressed “to the great Sea-god who girdles the world.” It is to Oceanus, not to Poseidon, that their thoughts are directed.

Invoked in passing by poets and figured as the father of rivers and streams, thus the progenitor of river gods, Oceanus appears only once in myth, as a representative of the archaic world that Heracles constantly threatened and bested. Heracles forced the loan from Helios of his golden bowl, in order to cross the wide expanse of the Ocean on his trip to the Hesperides. When Oceanus tossed the bowl, Heracles threatened him and stilled his waves. The journey of Heracles in the sun-bowl upon Oceanus was a favored theme among painters of Attic pottery.

Oceanus prefers to keep combat as quick and deadly as possible. As always, Oceanus’ preferred targets against which to express his rage are any Daemons which he can sense. Against such foes, he will respond by sending a tidal wave after them, forcing them into the water where he can crush them to death, or use a persistent Waterspout or empowered Crumble to blow away or disintegrate respectively any settlements or bases that they may have formed in Porphatys.

Should Oceanus encounter a foe that is immune to acid, he will use corrosion vulnerability against them at first, and then follow it up immediately by attempting to dissolve them out of spite.

Spell-Like Abilities (Sp): At will: alter self, analyze dweomer, commune with nature, cure critical wounds ,elemental swarm: eyebite ,endure elements ,fly, freedom of movement,freezing sphere, fog cloud, Maelstrom, produce flame, protection from energy, read magic, remove curse, sanctuary, sending, soften earth and stone, sound burst, speak with animals, speak with plants, summon monster VI, greater teleport, wall of ice, water breathing, Waterspout, wind wall.

3/day: antilife shell, astral projection, contact other plane, greater dispel magic, greater scrying, invisibility purge, plane shift.

Caster level 88th; save DC 21 + spell level. The save DCs are Charisma-based.

Acrid (Ex): Oceanus may alter the nature of the water around him, increasing it’s natural acidity drastically to the point where it is damaging, even lethal, to those unfortunate enough to be immersed in it. Each round as a standard action, Oceanus may acidify 400 cubic feet of water around his immediate person. Changes that he has made in the water in this manner do not take effect immediately, instead taking effect over the course of 2 plus 1d4 rounds. Beings that are in a sailing vessel above the water may notice a change in the smell of the water by using a Survival check DC 14.

Alternately, Oceanus may also choose to acidify a living being instantaneously. They must make a Fort save DC 68 or else be turned into a puddle of corroded goo, making them unrecoverable except through the use of the Hand of Life Salient Divine Ability or a similar power. Any spell that does elemental-based damage that

Oceanus casts furthermore may also do acidic damage as if he had taken the Energy Substitution (Acid) feat, and by taking a full round of casting time, Oceanus may modify his spells so that they may do damage as if Oceanus had taken the Energy Admixture (Acid) feat. The latter use of his Acrid power does not increase the spell level of spells modified in this manner.

Finally, Oceanus’ natural attacks are empowered by his own acid, doing an additional 3d6 points of acid damage upon each successful hit, double this amount on a critical hit, and any being that gets within 10 feet of him must make a Fort save DC 68 or else take 2 points of Constitution damage/round due to inhalation of acidic fumes.

Oceanus possesses Divine Rank 0, and grants spells from the domains of Corruption and Water although due to attempts from virtually every faction of Tartarus to slaughter his worshippers, he has practically none left at this point. Oceanus is treated as a unique creature with regards to summoning attempts like the spell gate.

Lord of the Corrosive Seas (Su): Out of all of the Ancient Titans imprisoned within Tartarus, Oceanus possesses the greatest degree of control over his personal demensne. Oceanus’ control takes the following forms, both in terms of his personal power and his influence over Porphatys itself:

Torrent: Oceanus may send a flood of corrosive Porphatys acid against any location which he may sense with his Visions of the Corrosive Seas. Doing so takes one round of Concentration for every 10 feet of the wall of water’s height, and any Torrent that Oceanus unleashes may have a maximal height of 150 feet. Once a Torrent is unleashed, it behaves in a manner analogous to a Tidal Surge spell, except that it uses Oceanus’ own Strength (Strength 60) in order to determine the saving throw against the bull rush.

Visions of the Corrosive Seas: Oceanus may scry through any Porphatys acid within an 880 foot radius around himself as the spell as a full-round action. However, Oceanus lacks the ability to scry through natural water.

Vortex: Oceanus is so closely associated with water, even in the degraded and corrosive environs of Porphatys, that his natural form resembles that of a Primal Water Elemental. As long as Oceanus is in his new ‘natural’ form, he gains the ability to transform himself into a whirlpool once every 10 minutes, provided he is underwater, and remain in that form for up to 1 round for every 2 HD it has (44 rounds).

In vortex form, he can move through the water or along the bottom at its Swim speed. The vortex is 5 feet wide at the base, up to 50 feet wide at the top, and up to 80 feet tall. Oceanus controls its exact height, but it must be at least 10 feet. Gargantuan and smaller creatures might take damage when caught in the vortex and may be swept up by it.

An affected creature must succeed at a Reflex save (DC 69) when it comes into contact with the vortex or take 4d10 points of damage. It must also succeed at a second Reflex save (DC 79) or be picked up bodily and held suspended in the powerful currents, automatically taking 4d10 points of damage each round. A creature that can Swim is allowed a Reflex save (DC 79) each round to escape the vortex.

The creature still takes damage, but can leave if the save is successful. Oceanus can eject any carried creatures whenever it wishes, depositing them wherever the vortex happens to be. If the vortex’s base touches the bottom, it creates a swirling cloud of debris.

This cloud is centered on Oceanus and has a diameter equal to half the vortex’s height. The cloud obscures all vision, including Darkvision, beyond 5 feet. Creatures 5 feet away have one-half concealment, while those farther away have total concealment. Those caught in the cloud must succeed at a Concentration check (DC 69) to cast a spell. The DC is Strength-based.

Finally, in addition to his Druidic spells, Oceanus retained his ability to transform himself and possesses the ability to wild shape himself six times a day into any form from tiny to gargantuan in size. Oceanus may additionally wild shape into any magical beast that possesses the Aquatic or Water subtype.

However, Oceanus is slowly weakening with each century that passes, and as a result Oceanus has trouble maintaining his form. This slow degeneration of Oceanus forces Oceanus to use one of his wild shape attempts in order to shift into his natural, Ophion form and doing so causes Oceanus great pain. After the first 4 rounds that Oceanus shifts into Ophion, he is treated as wracked as the spell.

After these four rounds pass, Oceanus takes 1d6 points of Strength and Dexterity damage per round as the pain of his ailment incapacitates him. Oceanus can be brought to 0 Strength or 0 Dexterity through damaging himself in such a manner; when that occurs, he automatically shifts back into the water-form for which he is better known at present.

Spells (Sp) (0th-13th level): 6/9/9/9/9/8/7/7/7/6/2/2/2/1: Although Oceanus fell into evil thousands of millenia ago, Oceanus still retains his ability to cast Druidic spells, and does so at 44th level except for spells that affect storms, which he casts at 45th level. Saving throws against his Druidic spells are DC 25 + spell level. The saving throw DC’s are Wisdom-based. Oceanus may cast 8 epic spells/day with a maximal Spellcraft DC of 124.

Blast of the Black Wyrm
[Conjuration]
Spellcraft DC: 114
Components: V, S
Casting Time: 1 action
Range: 300 ft.
Target: bolt 300 ft. by 5 ft.
Duration: Instantaneous
Saving Throw: Ref half
Spell Resistance: Yes
To Develop: 1,026,000 gp; 21 days; 41,040 XP. Seed: energy (DC 19) Factors: add 30 additional HD of damage (+60 DC), increase damage die to d10 (+20 DC), cast ten levels higher (+20 DC), add +10 to saving throw DC (+20 DC), 1-action casting (+20 DC). Mitigating Factors: 25d6 backlash (-25 DC), burn 2,000 XP (-20 DC).

Oceanus sprays from his mouth a blast of powerful, purified acid from his realm offorcing all beings within range of the blast to make a Ref save DC or else take 40d10 points of acid damage. For the purpose of resisting the blast of the black wyrm, it is cast ten levels higher, and the saving throw DC is DC 30 + spellcasting modifier.

Corrosion Vulnerability
Transmutation
Spellcraft DC: 123
Components: V, S
Casting Time: 1 action casting
Range: 300 ft.
Duration: Permanent
Saving Throw: Fortitude negates
Spell Resistance: Yes
To Develop: 1,107,000 gp; 23 days; 44,280 XP. Seed: transform (DC 21) Factors: change from target to area (+10 DC), change from area to 20 ft. radius (+2 DC), increase area by 1000% (+40 DC), increase saving throw by 20 (+40 DC), 1-action casting (+20 DC). Mitigating Factors: 10d6 backlash (-10 DC).

By casting this epic spell, a black mist erupts from Oceanus, swirling around every being within a radius of himself, lingering about them for a second before dissipating. While there appears to be little to no visible effect on beings that are vulnerable to this epic spell, this appearance is deceiving, as through it’s casting, Oceanus completely removes a being’s immunity to acid. Oceanus will typically follow up this casting with breath of the black wyrm.

Liquefaction
Transmutation
Spellcraft DC: 113
Components: V, S
Casting Time: 8 days, 11 minutes
Range: 240 ft. cone
Duration: Permanent
Saving Throw: No
Spell Resistance: No
To Develop: 1,017,000 gp; 21 days; 40,680 XP. Seed: transform (DC 21) Factors: remove 20 points of hardness (+40 DC), change from single object to area (+10 DC), change area to 40 ft. cone (+2 DC), increase area by 500% (+20 DC), 1-action casting (+20 DC).

Through casting this epic spell, Oceanus transforms every inanimate object that possesses 20 or fewer points of hardness within a 240 foot cone in front of him into an equivalent mass of water. While objects in the possession of living beings cannot be affected by this epic spell, it’s disastrous potential can become rapidly evident if, or when, Oceanus chooses to use it against the ground that a potential target stands on, or the ceiling above them.

Porphatys Adaptation
Transmutation
Spellcraft DC: 81
Components: V, S
Casting Time: 1 action casting
Range: 300 ft.
Duration: Permanent
Saving Throw: No (willing)
Spell Resistance: Yes
To Develop: 729,000 gp; 15 days; 29,160 XP. Seed: transform (DC 21) Factors: cast 30 levels higher (+60 DC), gain 20 levels to beat dispel check (+40 DC), Mitigating Factors: 10 minute casting (-20 DC), increase casting time by 8 days (-20 DC).

In addition to reversing a living being’s immunity to acid, Oceanus possesses the ability through this epic spell to make a being immune to acid, although the only intelligent being that he has ever done this for is his spouse, Tethys, in order to keep her from being vulnerable to dissolution through contact with him. This epic spell can only be used on a willing being, and Oceanus must still breach their Spell Resistance although it is cast 30 levels higher for the purposes of Spell Penetration.
