coords 50 54 in Stormsong valley is a rare crab, Crushstacean.
I've killed this crab at least 4 times on my main now, and every day his "rare" status seems to reset. He shows up as a star again, and drops loot again.
Loot is a shit blue ring (that can be scrapped though), and ~48 AP.
Nothing major, but still, grab it while doing dailies.
