A technique whose power is only matched by its complexity; the Limitless allows one to manipulate space.
Cursed Energy
Starting at 1st level, you can harness your negative feelings into a usable source of energy called cursed energy. These feelings can be harnessed into attacks or abilities. The amount of cursed energy you possess is based on your class; some classes use either Charisma or Wisdom as the modifier (the player’s choice).
Your Cursed Energy DC is 8 + your Cursed Energy modifier + your proficiency bonus.
Infinity
Beginning at 1st level, you gain the ability to use your manipulation over space to protect yourself effectively. As a bonus action for 1 Cursed Energy, you can encase yourself in a field of mathematical infinity, costing 1 Cursed Energy point per round. Whenever you are targeted by a weapon attack, spell, Cursed Energy attack roll, or any saving throw from a source outside your body, you roll a d6. On a 4 or higher, any attacks or spells made against you automatically fail to hit or harm you in any physical way. At 6th level, you must roll a 3 or higher, and at 11th level, you must roll a 2 or higher.
At 14th level, you may spend 6 additional Cursed Energy when using this feature to automatically roll a 6, spending 2 Cursed Energy at the beginning of each of your turns while it is active this way. You may also activate this ability as a reaction when you are targeted by an attack or an effect that you can see and that would cause you damage.
When you take the Dodge action while Infinity is activated, you gain advantage on the d6 roll, and you may grant its benefits to any creatures within your reach.
This feature does not work on attacks that you cannot see until you reach 6th level or against poisons.
Lapse Blue
At 3rd level, you may create another impossible concept, negative space. As an action, for X Cursed Energy, where X is as much as you choose to use, you pick an unoccupied space within 30 feet that you can see and create a 5-foot sphere. The space around that sphere attempts to fix itself, pulling all creatures within X times 5 feet of that point and forcing them to make a Strength saving throw. They take X + 2d8 force damage. On a failure, the opponents take full damage and are dragged to the singularity of blue. On a success, they only take half the damage.
When you use your Blue technique in its Maximum Output form, you may make it last for up to 1 minute, and as a bonus action, you may move the sphere anywhere within 30 feet 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 make the saving throw. You can dispel this technique as a free action.
Reversal Red
Once you reach 6th level, you gain the ability to reverse your Lapse Blue technique, creating a great amount of space. For every 2 Cursed Energy you spend, you may push one creature 20 feet and deal X + 4d8 force damage, where X is the Cursed Energy spent. The creature may make a Strength saving throw against your Cursed Energy DC. If the creature impacts a surface made of material at least as strong as steel before completing the forced movement, it instead takes damage as if it were falling, based on the remaining distance. For example, if a creature had 50 feet of movement remaining, it takes 5d6 damage.
When used with Maximum Output, the distance the opponent is launched doubles and the creature is knocked prone.
Maximum Technique: Hollow Purple
At the moment you achieve 11th level, you have learned how to mix positive and negative space, creating imaginary mass. After using one action to charge, you can use an action for 10 Cursed Energy to force every creature in a 100-foot line to make a Dexterity saving throw. On a failure, they take 20d12 force damage and are moved to the end of the line and gain 1 level of exhaustion. On a successful save, they take half damage and do not suffer any additional effects.
Domain Expansion: Unlimited Void
Finally, at 18th level, you have learned how to expand your own domain, showing the Unlimited Void to opponents. You can create a void in space that causes victims to receive all kinds of stimuli and information endlessly, restricting their thought processes and actions. Every creature caught in the domain expansion that is not touching you must attempt an Intelligence saving throw at the beginning of their turns. On a failure, they take 12d8 psychic damage and have their Intelligence, Wisdom, and Charisma scores become 1 and are unable to cast spells, attack, use magic items, understand language, or communicate in any intelligible way, and fall unconscious for 1 minute. At the end of every minute, the creature can repeat this saving throw, ending these effects on a success. This feature can also be ended by Greater Restoration or Wish.
