This small, lidded jar contains a sizable deformed insect that twitches and wriggles as if constantly undergoing a particularly painful death. A swarmlord’s jar has a lid, but the lid is fused to the rest of the jar and cannot be opened.
While a swarmlord’s jar is carried openly in one hand, it grants a +2 luck bonus on all saving throws attempted against the attacks of swarms, and reduces swarm damage taken by the target by 5 points. These effects do not stack if more than one jar is carried.
A swarmlord’s jar can be thrown to shatter at any point within 30 feet. If the jar shatters in a square that isn’t currently occupied by an existing swarm, it creates a locust swarm that follows the thrower’s mental commands; these commands may be issued as a free action. If the jar shatters in a square occupied by a swarm, the swarm must succeed at a DC 15 Will save or become controlled by the thrower. Issuing mental commands to a swarm (whether it’s a freshly created locust swarm or a controlled swarm) is a move action, but once the swarm has been issued orders, it continues to follow those orders until it’s destroyed or the magic of the swarmlord’s jar ends. A locust swarm created by this item lasts for 1 minute if not destroyed earlier. Likewise, control granted by the jar lasts for 1 minute. Used against a worm that walks, a swarmlord’s jar merely deals 6d6 points of damage on a successful touch attack as it shatters (Will DC 15 half).
