Today, I have the two completed Clamavus (Clamavuses, Clamavusi?!?) for my Genestealer Cults. Much like the Primus and Magnus before, I painted one in orange overalls and one in blue overalls to help distinguish between them on the battlefield.
These two will provide some nice boosts for the army, giving nearby units +1 to charge and advance moves, as well as +1 Ld to help with morale. They also prevent enemy reserves from deploying within 12". In addition, they can belt out some bangin' tunes with those sound systems!
