Lore

A sapper who fortifies the field with a shovel. Catapult, springald, Greek-fire projectors, and boiling oil suppress foes while TNT Rush and Fieldworks raise pressure.

Greek Fire deploys a continuous flamethrower that detonates with Tactical Withdrawal. Boiling oil pulls enemies inward for focused bombardment.

Promotion to Siege Warden unlocks brace, spring rip, Greek wash, net traps, and a shell cannon before Bombardment plants a fire battery.

The Battery Captain masters Siege Barrage, Piercing Salvo, Cactus Rush, and Blaze Weave before Grand Battery reshapes the battlefield into a bombardment zone.
