Leeching Tentacle

"“You notice pricking feeling in the fingers of your left arm, as though it had fallen asleep. Lifting your arm to inspect them, you watch as your entire forearm bends away from you, swaying like a thin tree branch. A deep glow seems to be emanating from within, and grows in intensity as though rising from a great depth. Your arm has become completely numb, and it is remarkably painless as you see the meat of your forearm explode outwards to make way for the writhing mass of blue flesh that is growing within it. A long, slick tentacle slides away from the severed flesh, and stretches out to its full length.” —In-game description"
