Chapter 3: Avernus - Path of Devils - Baldur's Gate: Descent Into Avernus

Chapter 3: Avernus - Path of Devils. Demon Zapper Diagram 3.3: Path of Devils The purest of souls lures fiends into a hellish trap. Zap! Zap! -The Cartographer When the characters approach this location, read or paraphrase the following boxed text to the players: Radiant light cascades from a rusted metal monument shaped like the upraised mandibles of a giant beetle. The light cascades from a unicorn named Mooncolor, who is trapped inside a 10-foot-diameter sphere of magical force that prevents any matter from passing into it and blocks any spells cast into or out of it. The sphere is suspended between the zapper's spines, 50 feet above the ground. This light lures demons like moths to a flame, annihilating them when they get close. While trapped in the sphere, the unicorn can't use any of its magical abilities. The sphere targets the nearest fiend that moves within 100 feet of it, discharging a beam of radiance that forms a line 5 feet wide and up to 100 feet long, extending to the target. Any creature in the line that has 100 hit points or fewer disintegrates into a pile of ash. Creatures with more than 100 hit points in the line must make a 18 Dexterity saving throw, taking 260 (40d12) radiant damage on a failed save, or half as much damage on a successful one. Once the demon zapper has fired, it must recharge for 1 minute before it can fire again. To free the unicorn, the characters must destroy the rusted metal structure around it, which has AC 14, 250 hit points, and immunity to poison and psychic damage. The structure crumbles when it drops to 0 hit points, causing the sphere of force to slowly sink to the ground and fade away. If the characters free the unicorn, it accompanies them if they are of mostly good alignment. Ralzala the Dao A dao named Ralzala defends the demon zapper.
