This hideous scorpion is a nasty, black, twenty-foot-long menace. Its chitinous armor is a tangle of cruel hooked spikes and cracks that leaks ichor. It has three scorpion tails instead of one, and the tips of each tail sport several long, green crystalline stingers and plates, looking like some sort of dangerous fanged flower.
