## Atlantean Magic

Deep underneath the waves, where the light of the sun is filtered from the deep sea, Triton, Sea Elves, and other waterborne lineages gather together to protect the overworld from the deep sea monstrosities, aberrations, and elementals that seek to wreak havoc and destruction upon the material plane. After generations of fighting these creatures and protecting themselves, these deep sea protectors have developed a special kind of magic to be used deep within the waves, inspired by the deep sea creatures that they fight alongside with.

## How to Learn Atlantean Magic

Atlantean spells are inherently more powerful spells than most. Due to their innate ability of becoming empowered underwater and in the sea, Atlantean spells are made with the intention that they have the possibility of becoming more powerful than traditional spells given to characters. Because of this, Atlantean spells cannot be chosen normally and can only be taught from those who know Atlantean magic, or found via scroll or spellbook. Although it is possible for a divine or primordial entity to bless a spellcaster with the knowledge of one such Atlantean spell, the traditional way to learn these Atlantean spells would be through an Atlantean NPC or scroll/spellbook.

If a character wants to learn a Atlantean spell from an NPC, the character must take the downtime activity ‘Training’ as mentioned in Xanathar’s Guide to Everything Downtime Revisited, spending 50gp per week as opposed to 25. The character must have a friendly contact or favor with someone who knows a Atlantean spell of at least 3rd level. At the end of the Training, the character may then add one Atlantean spell that the contact knows to their list of Spells Known, provided it is of spell level that the character can cast.

Furthermore, if a character wishes to learn a Atlantean spell of 5th level or higher, the time spent in training is doubled, and the price per keep in costs of arcane supplies is 200gp per week.

## Prepared vs Known Casters
   When it comes to Atlantean spells, if a character learns a Atlantean spell it is either, added to their spellbook as normal if they are a wizard, it is added to their number of spells known if they are a Bard, Sorcerer, Ranger, or Warlock, and if they are a Artificer, Druid, or Cleric; it is added to their spell list and is automatically prepared without counting against the number of prepared spells that the caster can prepare.

## Submerged in Seawater

As you begin to read through these Atlantean Magic spells, you may notice that many of which contain an addendum that states, ‘When submerged in seawater.’ Since Atlantean spells were created to be used in oceanic environments, they are heightened when casted underwater, and as such, gain additional effects when the caster is fully submerged in Seawater, or when thet target of the spell is fully submerged in Seawater. If the effect of the spell has a duration that is longer than instantaneous, if the caster is no longer submerged in seawater during the duration of the spell, any amplified effects end as they are no longer being bolstered by the sea.

You raise your hands and conjure two spectral eels to swim around you. As a bonus action, you can make up to two melee spell attacks against creatures you can see within 15 feet of you, dealing 2d8 piercing damage on hit, as the eels snap and bite at creatures of your choice.

#### Pressuresnap
*7th-level evocation*
___
- **Casting Time:** 1 action
- **Range:** 60 feet
- **Components:** S
- **Duration:** Instantaneous

You snap, and create an impossibly pressurized bubble of air that shoots outwards from your palm at blinding speed. Make a ranged spell attack. On hit, you deal 10d12 bludgeoning damage. If your spell attack exceeds the target’s AC by 5, the target’s speed is halved and they cannot take reactions until the start of your next turn as they are dazed by the sheer force and sound of the blast.

This spell can only be cast underwater, and if this spell is casted while you are not underwater, the spell fails and your action is wasted.

#### Wrath of Zhragthonu
*9th-level conjuration*
___
- **Casting Time:** 1 action
- **Range:** 500 feet 
- **Components:** V, S, M (A black diamond worth 1,500gp)
- **Duration:** Concentration, up to 1 minute

You call upon Zhragthonu, the mouth of the abyssal depths, to swallow those into the soundless and lightless nothingness of the deep sea abyss. You summon a massive, blackened abyssal maw at a point within range that takes up in a 80 foot cube. This cube is difficult terrain, and each creature within this space must succeed on a Strength saving throw or become Restrained, as this incarnation of this ancient abyssal entity begins to swallow them whole. A creature also has to make this saving throw if they move into this space for the first time on a turn or if they start their turn within this space.

A creature can attempt to escape the maw by using their action to make a Strength check against your spell save DC, freeing themself upon a success. While a creature is restrained from this spell, they take 4d10 necrotic damage at the start of each of their turns, and must succeed on a Strength saving throw, or be pulled deeper into the maw. On one failure, they have disadvantage on all Strength checks made to escape the maw. On two failures, they are also Blinded and Deafened. On three failures, the maw of Zhragthonu swallows them, and they are instantly killed and transported into the deepest reaches of the abyssal sea in the lair of Zhragthonu.
