Zapphauser

Zapphauser is a lightning-themed mini-boss found in The Future chapter, floating above the battlefield and attacking with map-wide electrical bursts. With 125 HP, Constitution 3, Speed 20, and Teleport movement, he is extraordinarily fast and difficult to pin down. His core mechanic: whenever struck, he teleports out of the arena and primes a plus-shaped thunderbolt attack targeting the tile of the unit that hit him, which detonates on his next turn.

Zapphauser attacks all tiles of the same parity as his own position with LEBurst — a checkerboard-pattern lightning strike that covers half the arena. His reactive counterattack means every hit marks the attacker for a follow-up thunderbolt, incentivizing rapid repositioning after attacking. Abilities that trigger automatic attacks (Tower Defense, Kinetic Spikes) are extremely dangerous here and can create infinite loop scenarios. Tinkerer Robots gain energy from his lightning attacks, offering an unusual synergy.

Tile parity awareness is essential — position units carefully between attacks to avoid the checkerboard blast. Immobilization effects are highly effective: while immobilized, Zapphauser cannot execute counterattack jumps. Gravity-type abilities work well since he floats. His Constitution 3 means he is comparatively fragile once locked down — burst damage during an immobilized window can end the fight quickly.
