I'm running SKT Adventurer's League and need a token to represent the greed motes: Appearing around the room are three masses of translucent
green energy. These masses pulse in rhythm with the light of
the diamond, as if they are all connected by energy. The
masses move toward you, lashing out with barb-tipped
tentacles. With each lash, the synchronized pulsing of the
creatures and the diamond grow brighter. If I can't find something I might just try to find an image of rain and give it a green hue. Happy to slip someone a buck for their trouble.
