Limitless
With Dagon's technique, all water related spells doesn't take any components or spell slots. Also all water based spells do double of what ever. Can use this equal to your proficiency bonus until a long rest

Cursed Energy: LV x 5, regain 5 at the start of turn
Regen: # of Cursed energy x 20 hp as bonus action or reaction
Six Eyes: Constantly under the spell Foresight: For the duration, the target can’t be surprised and has advantage on attack rolls, ability checks, and saving throws. Additionally, other creatures have disadvantage on attack rolls against the target for the duration. Also has 120ft Truesight and can see the energy of other anime abilities and by doing a DC 40 Arcana check, you can understand its nature. Every feature that uses Cursed Energy will instead cost 0.5 times its original cost in Cursed Energy unless stated otherwise
Maximum Output: As a bonus action, you must spend Cursed Energy equal to the original cost of one of your lapse, reversal, extension, or maximum techniques twice. The first time you pay this cost, any reductions that apply to the technique are used; the second time, none are applied. Doing this will amplify its cursed energy output, making it gain two of the following benefits the next time it's cast:
-The technique's range and area of effect are increased by half its original range, rounded to the highest 5. This range increase does not work with touch-based techniques.
-The technique's damage dice is increased by half of its original dice or damage bonus if the technique is a flat damage rounded up. For example, a technique with 10d10 die of damage would add 5d10 die of damage to the total damage die.
-The technique's bonus to hit is increased by half of its original bonus rounded up. For example, a technique with a +7 to hit would add a +4 to hit in its maximum output form.
-The technique's DC is increased by half of your proficiency bonus rounded up.
-The technique's duration is increased by half of its original duration. For example, a technique that lasts a minute would last 1 minute and 5 rounds. You cannot choose the same benefit twice

Infinity: As an action for 20 Cursed Energy, you can cause the space around you to divide into infinite fractions for 1 minute. Whenever you are targeted by a weapon, grapple, spell, melee cursed energy attack roll, ranged cursed energy attack roll or any saving throws from sources outside your body, you may use a Reaction to spend 1 Cursed Energy and roll a d20. On an 4 or higher, any attacks or spells made against you automatically fail to hit or harm you in any physical way, also once per round you can get an automatic 20 on the dice. Additionally, you gain a number of additional reactions equal to your Charisma modifier + your proficiency bonus that can be used exclusively for this feature. You may also activate this ability as a reaction to being targeted by an attack or effect that would cause you damage that you can see. When you take the Dodge action while Infinity is activated, you may use your Infinity reactions to defend a number of creatures within your reach equal to your number of arms with Infinity alongside yourself. Regardless of level, this feature only works on things that travel and can be stopped. Abilities that do not physically travel will not be stopped by Infinity
(Cursed Energy no longer required thx to Six Eyes)

Blue: As an action for 10 Cursed Energy, you may cause space to be erased within 30 ft of you causing a blue sphere with a 10 ft. circle radius to draw everything towards it for 1 minute. All creatures within this area must make a Strength saving throw. On a failure, they take 16d10 force damage, are restrained until the beginning of their next turn, and are pulled to an open space closest to the center of the sphere. On a success, they take half as much damage and are not restrained or pulled. A creature can retry this saving throw at the beginning of each of their turns. If they succeed, they take half the damage and exit the sphere. If they fail, they remain there without being able to move and retake the damage. Any creatures that enter the sphere's range or start their turns in the sphere's range must also make the Strength saving throw. You can dispel this technique as a free action. Objects within the area that aren’t being worn or carried also take this damage. When you use your blue technique in its Maximum Output form you may spend a bonus action to move the sphere anywhere within 30 ft. of the original place. All creatures currently stuck in the sphere will be moved as well, and any creatures caught in the range of the sphere moving must do the saving throw.
Blue Redirection. Whenever a projectile, ranged attack roll, or spell/technique with a line area passes through Blue's area of effect, it is attracted to the center of the sphere. If said technique or attack would deal less damage than Blue, it is pulled in and stopped completely, missing its target in the case of an attack and being cut short in case of a line effect. If it is a projectile, it also takes Blue's damage. In the case of a line effect, it now changes its trajectory, with its area starting from the first point where it entered Blue's area of effect and ending at the center of the sphere. If any other creatures are in that area, they are affected by the line effect as normal. If the attack or line effect would deal more damage than Blue, it ignores this and works as normal, but its damage is reduced by Blue's damage.
Blue Manipulation. You have learned how to use blue to manipulate space more precisely. As an action for 10 Cursed Energy, you can precisely manipulate your Blue in order to cast telekinesis. Any adjustments used to enhance Blue besides effects that increase your damage dice also apply to this (including range increases and Cursed Energy cost reductions), and the distance you can move anything you've grabbed is equal to your base movement speed; If you have Simultaneous Casting you can cast this a number of additional times equal to your Charisma modifier to target more items, or to target the same item multiple times. This lets you double the weight limit per stack when focusing on one object, or to impose multiple Strength saves on the same target if they continue to escape. If you attempt to throw an object at someone in its range, you may treat the object as if it is under the effects of the Animate Object spell, dealing damage respective to its size; additionally, objects you manipulate that otherwise lack stat blocks can use these stat blocks if someone should attack them. For the purposes of commanding gargantuan objects (something normally impossible with Animate Objects), you can refer to this stat block: HP: 120, AC: 8, STR: 22, DEX: 4, Throw Attack: The creature must make a Dexterity saving throw, on a failure they take 4d12+6 bludgeoning damage and half as much on a success. If you attempt to throw a person at another person or object, they will be treated as a medium object regardless of size, and the damage dealt will be dealt back onto them. Additionally, for every 10 feet an object travels whilst closing the distance to its target, it gains an additional d8 of damage, up to a maximum of 12d8. This can be used out of combat to freely manipulate tiny objects at no cost.
Pulse Blue. You have learned to fire off your blue in a quick burst, weaponizing its attraction effect for damage rather than utility. As an action you can cast blue, instead firing it as a ranged cursed energy attack roll against a creature within 60ft of you. This use of blue does half of blue's damage, and does not pull creatures or linger after it has been cast

Teleport Technique: Basic Teleport: When you move, you may spend 6 Cursed Energy to teleport instead of walking. This movement does not provoke opportunity attacks. The first attack you make after teleporting has advantage unless the target’s passive Perception is higher than your Cursed Energy save DC. Reactive Teleport: As a reaction when you're targeted by an attack, spell, cursed energy attack, or saving throw, you can spend 5 Cursed Energy to teleport up to your movement speed to a visible empty space. If the effect is an attack roll, make a Dexterity check against the attack roll. If it's a saving throw or AoE, make a Dexterity check against the effect’s save DC. On a success, you teleport before the effect resolves and avoid it. On a failure, you teleport after the effect hits you. Aerial Boost: When you move, you can spend 6 Cursed Energy to gain a flying (hover) speed equal to your walking speed for 1 minute. You can extend this by spending 1 Cursed Energy per additional minute. You may grant this flight to any creature you're holding or sharing Infinity with.
Blue Augmented Speed: You can boost your speed using spatial compression. As a bonus action, spend up to your Charisma modifier in Cursed Energy to gain +10 ft. of movement per energy spent. This speed boost lasts for a number of rounds equal to your Charisma modifier
Space Manipulation: You can now cast Teleport as an action for 10 Cursed Energy, but with the following changes: Destination must be within 10 miles × your level. You must have a clear, unobstructed path to the location (e.g., open sky, visible hallway). If you have the Six Eyes, the range expands to anywhere on the same planet, and you always arrive exactly where intended

Red: As an action for 10 Cursed Energy, choose a point within 40 feet. All creatures within the range of the explosion centered on that point must make a Strength saving throw. On a failure, they are knocked back 100 feet, take 32d8 Force damage, and are knocked prone. On a success, the damage is halved and they are not knocked back nor prone. The explosion range can be a radius from 5 ft. up to 30 ft. (your choice). Alternatively, you may make a ranged cursed energy attack roll against a creature up to 120 feet away, shooting a more precise version of red that targets only said creature. On a hit, the creature takes Red's damage, and must make the Strength saving throw as normal to be knocked back. This technique deals twice as much damage to objects and structures. Objects within the area that aren’t being worn or carried also take this damage. You may grant the benefits of Simultaneous casting to your reversal

Simultaneous Casting: You have mastered the art of utilizing cursed energy. When you cast Blue/Red you may pay its cost an additional amount of times up to half your Charisma modifier (rounded down), creating an additional Blue/Red within 5ft. of the initial blue/red for each additional time you pay the cost. The additional blues/reds will deal the damage of the original and will not restrain the target. Alternatively, you can shoot them like projectiles following the rules for cursed projectiles but they do your blues/reds damage, and these attacks can replace any number of attacks on your turn.

Hollow Purple: You have also learned how to mix blue and red, creating a purple bolt of cursed energy that destroys everything in its path. As an action for 30 Cursed Energy, force every creature in a 15-foot wide 360-foot long line must make a Dexterity saving throw at disadvantage. On a failure, they take 30d12 force damage. On a successful save, they take half damage and do not take the additional effects. Objects within the area that aren’t being worn or carried also take this damage. If this damage reduces a creature or object to 0 hit points, that creature or object is disintegrated. This counts as an extension technique for the purposes of other features

Simple Domain: You surround yourself with a 15 ft. barrier for 1 minute. The circle has 180 hitpoints. Any cursed techniques or spells that target them or target an area that overlaps with their simple domain will now target the barrier instead, reducing its hit points by the damage it would cause. To use this technique, you must maintain concentration as if you were concentrating on a spell. If you are in a Domain Expansion, then you negate its sure-hit effect on himself and any other creatures inside the area, as it only affects the barrier. Your simple domain dampens techniques that any innate techniques or spells that target him, creatures inside your simple domain, or targets an area that overlaps with your simple domain, will have its damage dice reduced by 18 dice. If it does not deal damage, it will instead have its Cursed Save DC reduced by 9

DOMAIN EXPANSION: UNLIMITED VOID

Full Domain: As an action, 50 cursed energy, any targets within 60ft of you, friend or foe must make a WIS saving throw against your spell DC. On a failure, they take 20d8 psychic damage and have their Intelligence, Wisdom, and Charisma scores become 1 and are unable to do anything. On a success, they take half psychic damage and are incapacitated until the beginning of their next turn, and don’t need to make their next saving throws against this use of Unlimited Void. At the end of every turn, the creature can repeat this saving throw, ending these effects on a success. This feature can also be ended by greater restoration or wish. If they get a nat 1, then they are brain-dead until someone else comes save them
0.2 seconds: As an action, 20 cursed energy, any targets within 60ft of you, friend or foe, must make a WIS saving throw against your spell DC. If they fail, their INT, WIS, and CHA become 1 and won't be able to to do anything unless they succeed their WIS saving throw at the end of their next turn or a greater restoration is used on the target. Can use it equal to half of your proficiency bonus per week
