Stun batons are common law enforcement tools. The damage they do can drop a target to zero hit points, but will not kill them, the victim awakening in ten minutes with one hit point. Stun batons trickle-charge from normal movement and will not run out of electrical energy under normal use conditions.
Advanced weapons can ignore primitive plate and hide protections.
Shock Damage
Shock damage represents the inevitable cuts, bruises, exhaustion, and terror of close combat.
Shock damage is only inflicted on a melee target if the hit roll fails, and it only applies if the target has an AC equal or less than that listed for the Shock.
Shock damage always includes the wielder’s attribute modifier and any bonus damage granted by weapon mods, foci, advanced tech, or other damage bonuses. An actual hit with a weapon never does less damage than Shock would otherwise inflict; if the user somehow rolls less damage, use the Shock damage instead.
Thus, if you had a Strength score of 14 and were swinging an oversized alien battle axe at a target with AC 13, you would inflict 3 points of damage on a miss; 2 from the weapon’s Shock, plus 1 from your Strength modifier. If you hit, you’d do at least 3 points.
