Explosives have the explode special property, which lists the amount of damage the explosion deals, the damage type, special effects (with a duration, if necessary), and the radius of the explosion. When you attack with this type of weapon or ammunition, aim at a grid intersection. Each creature within the blast radius takes the listed damage but can attempt a Reflex saving throw for half damage. If the explode special property has any special effects other than damage, they are negated with a successful saving throw. Some exploding weapons, such as smoke grenades, don’t deal damage, so they don’t include the damage and damage type entries.
