Helminth gun platform — Cathode Grace crit chance forever, weapon buff, guns clear. Rotorswell optional CC / chip.

Electric status on Gyre raises her crit chance. Cathode Grace adds more crit and energy regen — kills extend it, but dropping it triggers a long cooldown. Cathode Current also extends Rotorswell and forces extra discharges on kill.

• 1 Arcsphere — Gyratory sphere that shocks nearby enemies. Conductive Sphere amps projectiles that pass through.
• 2 Coil Horizon — Imploding sphere. Common Helminth slot (Roar / Pillage). Coil Recharge recalls it.
• 3 Cathode Grace — Crit chance + energy regen; kills extend duration. Cathode Current is the modern must-slot.
• 4 Rotorswell — Electric field + crit discharges. Reverse Rotorswell reflects damage as Electricity.
• Helminth over Coil Horizon (Roar / Pillage / Eclipse). Cathode Current on Grace.
