Invasion lightning channels and multi-target branching

Arc Surge is a high-tier magic weapon dropped by the Martian Saucer during the post-Golem Martian Madness invasion event. Upon use, it channels direct electric bolts toward the cursor position, striking hostiles without projectile travel delay. In addition to hitting the primary cursor coordinate, the electrical current branches out to zap up to two extra hostile targets located within forward line of sight, creating an electric web that clears charging ground troops and aerial attackers.

Instantaneous magical strikes and modifier synergy

The staff inflicts 180 base magic damage per blast while consuming 18 mana per attack cycle. Because its electrical bolts connect across screen space immediately, it tracks erratic aerial targets far more reliably than slow-moving projectile spells. The Mythical prefix delivers the best offensive enhancement, reducing mana drain while maximizing damage and critical strike output. Compared to the Laser Machinegun and Charged Blaster Cannon, it offers immediate multi-target burst power without requiring warmup charging or sustained standing channels.

Trivia

  • Its tooltip quote directly references Emperor Palpatine from the Star Wars franchise.
  • The lightning arcs produce bright illumination that briefly reveals dark subterranean caves.
