Smoke Grenade
Military and police forces use these weapons to create temporary concealment. On the round when it is thrown, a smoke grenade fills the four squares around it with smoke. On the following round, it fills all squares within 10 feet, and on the third round it fills all squares within 15 feet. The smoke obscures all sight, including the darkvision ability granted by night vision goggles. Any creature within the area has total concealment (attacks suffer a 50% miss chance, and the attacker can’t use sight to locate the target). It disperses after 10 rounds, though a moderate wind (11+ mph) disperses the smoke in 4 rounds and a strong wind (21+ mph) disperses it in 1 round. Smoke grenades are available in several colors, including white, red, yellow, green, and purple. As such, they can be used as signal devices.
The purchase DC given is for a box of 6 grenades.
Tear Gas Grenade
Military and police forces use these weapons to disperse crowds and smoke out hostage takers. On the round that it is thrown, a tear gas grenade fills a 5-foot radius with a cloud of irritant that causes eyes to fill with tears. On the following round, it fills a 10-foot radius, and on the third round it fills a 15-foot radius. It disperses after 10 rounds, though a moderate wind (11+ mph) disperses the smoke in 4 rounds and a strong wind (21+ mph) disperses it in 1 round.
A character caught in a cloud of tear gas must make a Fortitude save (DC 15) or be nauseated. This effect lasts as long as the character is in the cloud and for 1d6 rounds after he or she leaves the cloud. Those who succeed at their saves but remain in the cloud must continue to save each round. A gas mask renders the target immune to the effects. A wet cloth held over the eyes, nose, and mouth provides a +2 bonus on the Fortitude save.
The purchase DC given is for a box of 6 grenades.
Thermite Grenade
Thermite does not technically explode. Instead, it creates intense heat meant to burn or melt through an object upon which the grenade is set. Military forces use thermite grenades to quickly destroy key pieces of equipment.
The purchase DC given is for a box of 6 grenades.
White Phosphorus Grenade
White phosphorus grenades use an explosive charge to distribute burning phosphorus across the burst radius. Any target that takes damage from a White Phosphorus grenade is dealt an additional 1d6 points of fire damage in the following round and risks catching on fire.
In addition, a WP grenade creates a cloud of smoke. Treat a white phosphorus grenade as a smoke grenade (see above), except that it only fills squares within 5 feet of the explosion point.
