The SM4Z is an acronym denoting its core components - a shoulder-mounted, four-tube launcher with a tube size of Z. This formidable weapon is exceedingly heavy and cumbersome, weighing a substantial 400 pounds. The device features an arjale apparatus that securely holds four 3-foot Ceratimus tubes.
The SM4Z Pos-Grenade Launcher necessitates mounting upon the shoulder of a substantially sizeable and robust entity. Any entity possessing less than 20 strength attempting to discharge a single round from the weapon will be catapulted 1-10 feet and endure an equivalent amount of damage, accumulative for successive rounds. The operator must also possess a shoulder span of two feet or greater, lest they incur a -4 penalty to their likelihood of striking the intended target.
The weapon features a track that enables it to be fitted into a harness on the creature's back. The Githyanki refer to this as the "prortopino" position. Since the githyanki language lacks a direct term for "rest," linguists surmise that this phrase signifies "preparation" in their vernacular. The alternative position is the "ackleek" or attack posture.
The SM4Z can discharge four energy grenades per volley. The weapon's accuracy diminishes proportionally to the number of missiles expended. The grenade table should be consulted when this armament is utilized. The weapon maintains standard "to-hit" probabilities for direct engagements, while indirect fire encounters a -6 penalty. Each grenade necessitates a distinct "to-hit" roll. The weapon expends one Obelisk Charge per grenade launched.
