Speed Tank build, Flywire, Blast Boot, Tether Wail
Weapon is less important than the abilities on the weapon, I'm using a Five Star Primo Pulley Brush because it fits my play style.
CONSISTENT 100-200k damage. Baseline damage on just weapon is usually 17-21K. When explosion and freeze go off together with ferment easy 200k plus swings.
Usual loop: charge up tank abilities, drop wail, jump in and hit some big swings, use Flywire to exit then just go back and forth on the map jumping in and zipping off. Wail pulls enemies to center, let them collect then blast Boot, and hit for big damage on whole crowd. Once mega eggs start dropping they auto collect and explosions start chaining.
