Prismatic Soul

Your soul has been touched by the strange otherworldliness of the Mirror Realm, a twisted reflection of this world home to the Nerra, granting you their illusory powers. Perhaps one of your ancestors was a mirrored version of their original self, escaped from this Realm - or maybe your power stems from a duplicate of yours that is trying to break free. Whatever the case, this power is now yours to wield, beckoning you to see your potential as a force of change in the world.

Prismatic Magic

As a Prismatic Soul Sorcerer, your power manifests through you in ways that alter your body and the world around you, mirroring your own magical power. Consult the Reflections of Power table and choose or randomly determine a way your connection is reflected when casting your Sorcerer Spells.

Reflections of Power

1. Your eyes shine over and become mirror-like, reflecting what you see in them.
2. Reality splinters around you, creating reflective shards in the fabric of space that hover about you.
3. Your body shows cracks in it, like a broken mirror.
4. The verbal components for your spells are all spoken backwards.
5. Your spellcasting focus creates a mirrored duplicate of itself, which temporarily hovers around your head.
6. Your spells give off technicolor lights, as if the light shone through them is split in a prism.

Furthermore, you learn additional spells when you reach certain levels in this class, as shown on the Prismatic Spells table. Each spell counts as a sorcerer spell for you, but not against the number of sorcerer spells you know. These spells can’t be replaced when you gain a level in this class. When you gain a sorcerer level, you can replace one spell gained by this feature with another spell of the same level - new spell must be an illusion or conjuration spell from the sorcerer, warlock or wizard spell list.

The Other Side

Starting at 1st level, you gain the power to warp the world around you. As an action on your turn, you can choose one creature that you can see within 120ft of you. The creature cannot be you, and they must be Large or smaller. Harnessing the fractal power of the Mirror Realm, you create an illusory duplicate of that creature in an unoccupied space that you can see within 60ft of you. The Reflection lasts for 1 minute, or until you lose concentration on it as though you were concentrating on a spell. As a bonus action on your turn, you can move the illusion up to 30ft to a space you can see, and mimic some kind of action of your choosing, but it must remain within 120ft of you. If a Reflection is attacked, it is treated as having an AC equal to 10+Your Proficiency Bonus.

For the duration, you can cause the illusion to speak, either with your voice or perfectly mimicking the voice of the creature - provided you can understand the language spoken by the creature you are reflecting.
A successful Intelligence (Investigation) check of the Reflection against your Spell Save DC may reveal it to be nothing more than an illusion. You may use this feature a number of times equal to your proficiency bonus, regaining all expended uses on a long rest.

Prismatic Aspecting

At 6th level, your magics become twisted and warped, altering your spells with unnatural forces modified with your innate sorcerous power. Once during each of your turns, when you deal damage to a creature with one of your spells, you can replace the damage type dealt with force damage.

Recursive Image

Starting at 6th level, you become more difficult to pin down, as fractal images stand between attacks incurred against you. When a creature you can see within 30ft of you makes an attack roll against you, you can use your reaction to impose disadvantage on that attack roll - before the roll is made. You can use this feature a number of times equal to your proficiency bonus, regaining all expended uses on a long rest. Alternatively, you may spend 1 sorcery point to perform this reaction without requiring you to expend one of these uses.

Trick of the Light

Starting at 14th level, your Reflections grow more potent, becoming ever closer to the reality they mirror. When creating a Reflection, you may spend 1-4 sorcery points, gaining each of the following benefits based on how many points you spend on its creation.
1 - When an allied creature you can see is targeted for an attack, and is standing within 30ft of either you or a Reflection, you can use your Recursive Image to impose disadvantage on the attack roll targeting that ally.
2 - You may create two reflections at once, targeting two different creatures to mirror, or the same creature twice. You may move both reflections with the same bonus action, and you can speak through one or both of them at the same time.
3 - As a bonus action on your turn, you can magically swap places with a Reflection, provided you can see it.
4 - Your Reflections no longer require concentration to maintain them.

Prismatic Mind

At 18th level, you have unlocked the truth hidden within the reflections of this world, and can manifest it through yourself. As a bonus action, you can create a unique reflection of yourself, called a Prismatic Doppelganger. The Doppelganger is illusory in nature, and inhabits the same space that you do. It follows all your movements, mimicking them while slightly out of sync. It lasts for 1 minute, and while it is present, grants the following benefits.
-Your movement does not provoke opportunity attacks.
-Your AC gains a bonus equal to your Charisma modifier.
-When casting Illusion or Conjuration spells, you can reduce the cost of any sorcery points spent to modify these spells, to a minimum of 0.
Whenever you use this feature, you cannot use it again until you finish a long rest, unless you expend 3 sorcery points to use it again.
