Ballistic Battery stores damage, dumps it into the next shot. Ballistic Bullseye adds status. This is not the god build. It is a cannon.

Ballistic Battery is Mesa's worst ability, which is why every serious config Helminths it.

Key mistakes

Empty Regulator grid
Peacemaker is a secondary weapon. Hornet Strike at minimum. Treat it like a Laetum, not like an ability number.
Trusting Shatter Shield against melee
Ancients, heavy slams, and status will kill you during 4. Adaptation, roll, or Waltz out.
Keeping Ballistic Battery on a serious config
Helminth it. Nourish, Roar, Eclipse. The stored-shot meme is a different loadout.
Building 300% Strength 'for DR'
Shatter Shield caps at 95% around 119% Strength. Extra Strength is Peacemaker damage, not more DR.
