The Living Paradox

"Fight to the bitter end, no matter how cruel your failures are."

The Living Paradox: You have mastered your quantum state, weaponizing it's nature to become a living paradox, a being without a concrete past or future, immune to continuity. Your ki points themselves evolve into Quantum Uncertainty (QU) points, letting you perform the following actions by spending one or more QU points on them. Class features that reference ki points can now have QU points be used instead of ki points. Your QU points get multiplied by 10, and Mastery of Death becomes more potent. When you are subjected to an effect that would kill you instantaneously, that effect is instead negated against you, as your own personal timeline can't be altered for 1 QU point.

1) When a target you see fails or succeeds a saving throw, you can make them succeed or fail instead for 2 QU points.
2) As a reaction you can add or subtract your charisma modifier to a roll.
3) As a bonus action you can change the state of a target from their current state to another point in time when they were in a healthy state for 4 QU points. Buffs and debuffs they had are removed as they return to that point in time when they were healthy.
4) As an action you can increase or reduce a target's AC by your charisma modifier that you can see for one minute.
5) When you or an ally you can see would die, you can spend 5 QU points instead to negate their death.

Katana GrandMastery: When you wield a katana weapon, your quantum state is focused to an unprecedented level. All saving throws are considered magical when you hold a katana. When you hit or miss with a katana you gain the bonus to hit and damage equal to your charisma modifier. Once per long rest, you can combine the weapon properties and effects of a weapon you have with your bonded katana. You can learn the techniques and abilities of other Katana masters, adding them to your own skills, if you have dueled them on a quest, seen the ability happen, and won. When a hostile creature within reach of your katana attacks or casts a spell to an ally that is not you, you can attack the hostile creature.

"The strength of your spirit should never falter."

Interdimensional Freedom: The molecules in your body vibrate to make you a being of pure energy, able to create a physical body out of nothing. You can twilight travel instantaneously without restriction to time, space, or plane. Everything you are, you are also not, and are able to ignore effects or conditions on you equal to your charisma modifier per short rest. If the condition ignored can be negated by dispel magic or remove curse, roll a martial arts die. If the number rolled exceeds the level of the spell, you regain a charge of Interdimensional Freedom.

Soul Striker: You can see and cut to the heart of any being. Your vision and katana is potent enough to be able to attack a targets soul directly if it has one, ignoring AC, HP, and saving throws of the target's physical form. The target's soul's AC is an AC of 10 + cha mod + wis mod + int mod and the target's soul's HP is 200 + con score + dex score + strength score. When the target's hp is reduced to 0, you send the soul to your domain.

"To choose others over ourselves, to see beyond our own emotions, to be relentless and never stopping even for a moment, even at your own peril to protect comrades, even those who consider you an enemy, that is what it means to be a Swan."

Quantum Reaper: Your aura and dreadful glare creates a reaping aura around you that inflicts terror down to the soul. Your Hour of Reaping reaches for 90ft, and can only effect hostiles. Your paladin aura increases to 90ft as well. If the target is immune to fear they automatically fail the saving throw. It can be done as an item interaction instead of an action, and those who pass become vulnerable to your attacks while those who fail drop to 0 HP.

Strike of Certain Uncertainty: Your stunning strike can do more than just stun. When a target fails their saving throw, even if they legendary resist it, you can expend additional QU points to change parts of their statblock such as immunities, class, spells, abilities, and so forth as their physical form gets altered to that of another timeline and reality.

"We swore oaths on the sword together, we raced through time together, and we will do battle together. Even if a meaningless death lies at the end for you, it can still be the beginning of something new."

Mass Infinite Strikes: You can strike at lightspeed, with the force of a white dwarf star as the mass of your physical attacks reach a near infinite level. Your weapon strikes can cut atoms to trigger a nuclear explosion effecting only creatures and objects you choose, dealing and extra 4.384 x 10^30d10 irresistible force damage. Collateral damage from you strikes only effects the target of your strikes.

Death Delay: You have a reaction each turn, and can cast your spells at will. Divine smites have the effects of Divine Intervention, calling upon other deities or ascended being's abilities to aid you in battle. When struck, hostile creatures feel the same pain you do, no matter the immunities or resistances they have.
