Riff Tamson brings the planet of Mon Cala into the Clone Wars. Conspiring with Quarren chieftain, Nossor Ri, these devious diplomats in service to the Separatist Alliance manipulate events and thrust their unwitting foes into the fray.

Riff Tamson gives players a powerful and punishing hit-and-run unit, while Nossor Ri grants special abilities to allied Separatist Alliance units, especially when surrounded by aquatic units. Aqua Droids are well-armored and are able to reduce an enemy’s cover and strike with powerful melee hits.
