You realize that putting your hand in a dark hole in the trappers lair is just asking to be mutilated. You also have no choice. You jam your hand into the hole and feel around, you feel a number carved in the hole, It's a 2. Reaching around you find and remove a small scroll. One, two, three, four, aaaaaand five, yes you still have all your fingers. Time to see what is on this scroll.
