Dampener aerosol

The dampener aerosol was a specialized hand grenade. When activated, it produced a blue gas that caused particle streams to lose cohesion, dampening the impact of an affected blaster bolt to a painful slap.
== History ==
When infiltrating Ko Sai's underground laboratory on Dorumaa during the Clone Wars, Kal Skirata used a dampener aerosol during a shoot out with Manadalorian mercenaries under the Kaminoan's employ. Hayabusa shocktrooper fireteams were also known to make use of dampener aerosols, with a notable instance being Fireteam Hellfighter's escape from Kamino following the formation of the Galactic Empire in 983 ARR.
=== Alternate timelines ===
In an alternate timeline where the Galactic Empire was the aggressor in the Great War, the Office of Naval Intelligence were eventually able to reverse-engineer and mass-produce dampener aerosol technology, granting UNSC infantry forces an effective countermeasure against Imperial blaster weaponry.
