Wavelength (Wizard Archetype)

You hurl a crackle of ionic energy. Make a ranged spell attack. On hit, the target takes 1d8 lightning damage (scales as cantrips). On a hit against a device or construct, the target also takes 1 extra damage die.

You wrap yourself in a veil of shifting code. For the duration, you gain +1 to Dexterity (Stealth) checks and lightly obscure yourself; enemies have disadvantage on Perception checks that rely on sight to detect you.

You send a pulse across nearby systems. Choose a point you can see; creatures and devices in a 30-foot radius are scanned: you learn the number of creatures, whether they are living, constructs, or constructs with AI, and whether they hold active security measures. Creatures that are invisible are revealed as translucent images to you for the duration if they fail a Wisdom saving throw.

You infect a creature or device with a mischief routine. A creature must make an Intelligence saving throw. On a failure, the target has disadvantage on one skill of your choice and treats tools and devices as malfunctioning (disadvantage on use) for 1 minute. On a device, it checks and loses functionality for the same duration unless it succeeds on a Constitution save.

You create an illusory duplicate of a creature on the network or a holographic decoy in the real world. The decoy takes actions you direct. If attacked, it has AC 10 + your Intelligence modifier and 1 hit point per caster level. If destroyed, the illusion collapses.

You unleash a flurry of compressed data shards at a point. Creatures in a 15-foot radius must make a Dexterity saving throw, taking 3d6 lightning damage on a failed save, or half as much on success. Constructs and devices take an extra 1d6.

You create a vulnerability in a device or a creature's defenses. A device becomes susceptible to attacks (vulnerable to one damage type you choose) and grants you advantage on attempts to manipulate it. A creature's armor or natural defenses are reduced: it takes an extra 1d8 damage from your spells and has disadvantage on saving throws against your spells for the duration.

You unleash a spreading corruption that clings to constructs and living minds. Choose up to three targets within range. Each target must make an Intelligence saving throw. On a failure, constructs take 6d8 psychic/lightning damage and are stunned for 1 round; living creatures take 4d8 psychic damage and suffer disadvantage on Intelligence-based checks for 1 minute.

You attempt to seize a target's brief access protocols. One creature you can see must make a Wisdom saving throw. On a failure you control its actions for the duration (as dominate person but flavored as hijacking its short-term decision layer). Each time the target takes damage it can make another save to end the effect.

You rewind a small location's recent data: you and your allies can choose to reverse one non-permanent action that occurred within the last minute (objects returned to previous positions, a trap untriggered, a single spell's effect rewound). This cannot restore hit points or reverse death. The DM adjudicates plausibility.

A wave of corrupt logic shatters fragile systems. Non-magical constructs and devices in radius take 10d8 thunder and psychic damage (half on save). Creatures in the area that rely on tech suffer disadvantage on attack rolls and ability checks for 1 minute unless they make a Constitution saving throw.

You create a temporary micro-singularity of information. For the duration, you may manipulate the flow of time for devices and systems in range: reduce cooldowns, accelerate processes, and force constructs to make saving throws at disadvantage. Hostile creatures in the area take 12d8 force damage on a failed Constitution saving throw and are restrained by virtual cords for the duration if they fail by 5 or more.
