Supercyclical

Supercyclical is the 4-piece bonus of the Iron Battalion Set, an Iron Banner armor set. Securing final blows while your Super is active refunds some Super energy when the Super ends.

The bonus text gives no percentage. Guides differ on how the refund scales, with one tying it to kills made during the Super.

The 2-piece bonus is Primary Honing, which increases the handling and reload speed of all primary ammo weapons and adds extra damage against non-boss targets.
