Hummingbird Sword

The quest starts by killing the Troll King in his palace Located at the -300 level of Underkingdom. He Drops the Hummingbird Amulet which is traded in for the Hummingbird Sword.

Once you get the amulet, open the secret door at the SE corner of his throne room and step into the square while holding the amulet. You will be teleported to a room with an alter ringed in fire in the center. Stepping into the circle will cause whirl winds so have a balm ready. Once the whirlwinds have passed the Hummingbird sword will be left on the ground. Only one person with an amulet is to enter the secret room. More than one amulet in the room will result in a hummer not being left on the ground. To exit the room step back into the hex in the west wall.

Congrats on your Hummingbird Sword! Its Silver and blue glow and hits 2 times a round!
