Wondrous Item, rare (requires attunement by a Short rest to charge the capacitor)
A compact, glowing blue device with etched circuits and a single emitter coil—salvaged from the exploded constructs.
- Once per long rest, as an action, you can activate it to release a burst of energy. All creatures in a 10-foot radius must make a DC 12 Dexterity save, taking 2d6 force damage on a fail, or half on a success.
Notes: Short rest to charge the capacitor
