When a flare cartridge hits its target, it only deals half damage, but the creature struck is blinded for 1 round (Fort DC 15 reduces this to dazzled), and creatures within a 20-foot burst are dazzled for 1 round (Fort DC 15 negates the effect). Flare cartridges are also useful for sending up signal flares. Firing a flare cartridge increases the firearm’s misfire value by 2 unless it is fired from a blunderbuss or a dragon pistol, in which case doing so only increases the firearm’s misfire value by 1. Flares can only be used to attack single creatures; they do not work as a shot for a cone scatter attack.
