Illusion-Proof. The bolt-thrower is immune to figments. invisibility and other illusion spells that do not create figments affect the bolt-thrower normally.
Rooted. The bolt-thrower can use a bonus action to anchor or detach itself from a surface. While anchored, the bolt-thrower is grappled, and it cannot be moved or knocked prone. A bolt-thrower cannot use its heavy crossbow unless it is anchored.
Multiattack. The bolt-thrower attacks once with each of its crossbows.
Light Crossbow. Ranged Weapon Attack: +5 to hit, range 80/320 ft., one target. Hit: 7 (1d8 + 3) piercing damage.
Heavy Crossbow. Ranged Weapon Attack: +5 to hit, range 100/400 ft., one target. Hit: 8 (1d10 + 3) piercing damage.
Bolt throwers are among the most common dungeon security constructs, highly valued for their versatility—usable anywhere there’s a wall, ceiling, or roof—and not as time-intensive to create as their counterparts. Adventurers that practice care when dispatching a bolt-thrower (lowering its hit points to 0 without an attack that deals more than 15 damage) can recover both crossbows from its remains, although usually one of the two weapons survives regardless of how the creature is destroyed.
