Nanite-Infused Sorcerer

You fire a cascade of microscopic darts of nanites that strike a creature. Make a ranged spell attack; on hit the target takes 1d8 piercing force (scales with character level as a normal cantrip).

A reactive layer of nanites flares up, granting a +2 bonus to AC until the start of your next turn and negating Magic Missile effects against you.

You command nanites to mend wounds. A creature you touch regains 1d8 + your spellcasting modifier hit points. If you spend 1 additional nanite unit while casting, the healing increases by 1d8.

A concussive nanite pulse radiates from a point. Nonmagical technological devices in a 10-foot radius are disabled for 1d4 rounds unless repaired. Creatures in the area must make a Dexterity save or take 2d8 thunder damage and be stunned until the end of their next turn.

You spray a targeted creature with reactive nanites that cause corrosive micro-erosion: the target takes 1d6 acid damage immediately and 1d6 acid damage at the start of each of its turns for 1 minute. The target can make a Constitution save at the end of each of its turns (DC = your spell save DC) to end the effect.

You deploy a swarm of nanites that project holographic decoys. Aliies within 30 feet of you can benefit from half-cover provided by decoys; enemies attempting to target you or your allies must succeed on an Intelligence save or target a hologram (the spell then determines the outcome), granting disadvantage to attacks that target real creatures.

By directing nanites to restructure material, you can repair or slightly modify a nonmagical item (repair torn armor, solder a broken blade, or add a tiny functional upgrade). The process can also temporarily boost a simple weapon's damage die by one step for 1 hour if you spend 2 nanite units.

You create a 20-foot radius cloud of active nanites that deals 3d6 poison damage to creatures that enter or start their turn in the cloud. Creatures entering for the first time that turn must succeed a Constitution save or be poisoned for 1 minute (save at end of each of their turns). You may spend 2 nanite units when casting to make the cloud also heal allies for 2d6 hit points at the start of their turns while inside.

You reprogram your nanites for optimized performance: for 1 minute you gain +2 to AC, advantage on Strength and Dexterity checks, and your movement speed increases by 10 feet. You can instead channel this into an ally within touch range.

Your nanites form an adaptive weave over your body. You gain immunity to one condition of your choice (charmed, frightened, poisoned, etc.) and resistance to one damage type for the duration. You can change the chosen condition and damage type each hour as a bonus action by reprogramming.

You send a concentrated spear of compressive nanites at a point. All creatures in a 10-foot line must make a Dexterity save or take 8d8 force damage and be pushed 10 feet away and knocked prone. On a successful save they take half damage and are not knocked prone.

You attempt to seize control of one creature's bodily functions by rewriting nanite code within them (creature must have biological or cybernetic components). The target must make an Intelligence saving throw. On a failure you control that creature's movement and actions as if dominating it (like Dominate Person) for the duration. Successful save: immune for 24 hours.

You trigger a radical reconfiguration of your nanites to grant a one-time transformative effect: you may restore all your expended nanite units, regain all spell slots up to 5th level, and gain a permanent minor trait (choose one: minor telepathy within 60 feet, constant darkvision 60 feet, or a +1 bonus to a single ability score, max 20). After using Transcendent Rewrite, your nanites require a month of recalibration and this feature can't be used again until then.
