Try to hurt his balls again

He slowly rises to all fours but before he can stand, you run up behind him and kick his balls as hard as you can. He falls to the ground again and you slam your torch down onto his ball sack. His tough minotaur skin is so strong, however, that the flame of the torch goes out leaving only some very slight marks on his scrotum. You stomp his balls panicking and he roars out in pain. You grab each of his testicles which are as big as your fists and begin to squeeze. You squeeze and squeeze without mercy until the Minotaur passes out from pain. You still need to get out of the Labyrinth though before you are safe. You can run now and get a head start before he wakes up, or try to finish rupturing his balls so he will bleed out.
