At the time of this writing, roughly 18 cumulative hours in the camp. At around 3 spawns per hour, that means I've seen about 54 spawns on this throne room, and have only seen Retseth once. By my math and judging by my experience alone, that puts him at ABOUT a 2% spawn chance. I am continuing to camp him, but at the rate it's going, it will probably go even lower than that as time goes on. He's probably about a 1% spawn chance, if that. Stupid rare.
