Kain's first selection for an Evolutionary Base Material was the glowing "lure," or esca, of a Ether Lurefish. The Lurefish is an red-grade spiritual creature that resembles an anglerfish. It is quite ugly, and uses a glowing ball attached to its head via a rod to hunt for prey.
However, this is one of the few evolutionary materials that Kain had with dual water and light attributes, it also happened to be the cheapest.
After making the selection, Kain pressed the button to start the simulation and a glow began to emit from the Lumifin projected within the Simulator. However, the glow was much weaker than he remembered it being when testing Bea's and Aby's evolutions.
