15th-Level Relicwright Feature

Once per long rest, when you discharge, create two release spheres at different visible points within range and choose Pulse or Caress for each sphere. A creature in both can be affected by only one sphere, chosen by you; it makes at most one save and is moved at most once. Each Caress sphere can protect one willing creature. Both effects consume the same charge.

Veiled Play. If the charge is attuned, up to two willing instrument users across the spheres may each gain 1 Arousal to move 5 feet without provoking opportunity attacks. Unveiled Play. If the charge is attuned, you may spend 1 Libido to let up to your proficiency bonus willing instrument users across the spheres each reduce Arousal by 1, instead of granting the attuned-charge benefit of Resonant Release. Each creature benefits once.

Combat Identity

A technical controller and support inventor whose instruments separate preparation from release. Load the capacitor with an action, then discharge it with a bonus action for displacement or protection. Feedback Regulator can rescue a failed saving throw, while Echo of Release and Harmonic Array extend the usefulness of carefully timed resonance without creating an autonomous companion.

Desire Identity

Arousal is resonance offered by a willing instrument user; Libido is the endurance committed to attunement or regulation. The capacitor stores one mechanical charge, not a second Arousal track or a pool of recoverable Sparks. At 11th level, Echo of Release captures the aftermath of a qualifying Climax as one attuned charge. Breakthrough remains your separate, limited opportunity for a Spark-free activation.

Class Integration

Choose this Inventor Specialty at Relicwright level 3. It grants features at levels 3, 7, 11, and 15 and uses your existing Sparks, spell save DC, and Breakthrough. It does not add another specialty or replace your spellcasting, Sparkcraft, or Imbued Creations.

Spark Recovery. In Veiled Play, your first Spark expenditure on a Relicwright feature during an encounter gives you 1 Arousal after that feature resolves. In Unveiled Play, this occurs once per turn. Apply the feature’s selected play-mode effects separately; spending more than one Spark does not multiply Spark Recovery’s gain.

Breakthrough. After resolving your own Climax, the next Relicwright feature you activate that normally costs 1 Spark costs 0 Sparks until the end of your next turn, provided Breakthrough’s once-per-long-rest benefit is available. All other conditions and costs remain. Apply Breakthrough’s selected play-mode benefit from the Relicwright class. No Spark is spent, so Spark Recovery does not trigger. A specialty’s separate release benefit does not grant another Breakthrough use.

Ritual and Social Use

Tuning Ritual establishes a user’s preferred expression and an agreed signal before the instrument is used. In a workshop, sanctuary, or expedition camp, the engineer can demonstrate how to pause the apparatus and choose a signal that communicates a particular need. The signal is neither telepathy nor an emotional diagnosis. Only the ritual’s listed benefits apply, and each user retains control over contact and participation.

Example of Play

At 3rd level, hold the capacitor and use your action to spend 1 Spark and load it. In Veiled Play, a willing instrument user within 30 feet may gain 1 Arousal to attune the charge. Resolve your separate Spark Recovery gain after loading, if eligible. You can then use your bonus action to discharge Pulse at a visible point within 30 feet, choosing which creatures in its sphere must make the Strength save.

The discharge consumes the stored charge and spends no additional Spark, so it does not trigger Spark Recovery again. If the charge is attuned, an eligible willing instrument user in the sphere may use the selected play mode’s additional benefit. At 11th level, a qualifying Climax can instead let Echo of Release load an empty capacitor with your reaction once per long rest; that free charge is not a refunded Spark.

Additional Rules

Your two instruments and capacitor are reusable, require no attunement, and occupy no Imbued Creation slots. A loaded capacitor holds only one charge; loading again replaces the previous charge rather than adding another. That charge ends when discharged, replaced, or at your next long rest. Instruments have no actions of their own, and a user can pause or remove one freely.

From 5th level, Improved Spark can overcharge loading by spending one of the class feature’s limited overcharge uses, producing the range and push improvements stated in Resonant Release. Harmonic Array consumes a single charge for both spheres; an overlapping creature is affected by only one sphere. Echo of Release and Feedback Regulator both use your reaction, so they cannot both be used before that reaction is available again.

Unless a feature names another save, use your Relicwright spell save DC: 8 + your proficiency bonus + your Intelligence modifier. Build or prepare the reusable apparatus with appropriate proficient artisan’s tools or tinker’s tools during a long rest. Cosmetic description grants no unlisted range, target, damage, duration, or benefit.
