The Closed Feedback Circuit

2-piece: Feedback Grid

Casting a Groove-spending non-Ultimate ability places an Output Jack at its impact location for 8 sec, up to 3. Output Jacks connect into an energized network that continuously damages enemies caught within its fields and electrical pathways. For every continuous second an enemy remains in the Grid, its Grid damage increases by 10% cumulatively; leaving resets this buildup. Three active Jacks energize the area enclosed between them. Creating a fourth Jack replaces the oldest.

3-piece: High-Gain Signal

While an Output Jack is active, successful Basic Attacks gain 100% bonus Lightning Damage and discharge through every Output Jack, electrocuting nearby enemies. Closed Feedback affinity can increase the routed Lightning bonus up to 300%. Basic Attack, Lightning, Elemental, Crit, Attack Speed, and Groove-focused builds further strengthen the set through their normal effects.
