You kill enemies to get the clusters, sometimes when the ritual stones go pop, they drop shinies, that you need to destroy to get a higher amount of clusters, but you still keep killing mobs.

Favorite the objective. it will give a blue star on mini map when near. look for a yellow glow and attack it
