This is the largest of the rolling ARCs, a massive, spherical construct designed to dominate open ground. Its primary tactic is to stop periodically on the battlefield to transmit disruptive signals, acting as a massive relay for the ARC network. Be warned, however, its most unique (and dangerous) trait is its resilience: as it takes damage, its outer shell breaks apart into many smaller, armored pieces. Its final attack is a relentless one: it will roll directly at high speed toward any Raider it detects, essentially turning itself into a giant, high-impact bowling ball.
