Bigfoot's Burden Quest/Spoiler

Beginning - access to new gnome area
First, go to Kazordoon and seek out Xelvar. Ask him to join and he will give you 4 Teleport Crystals to go to the new area.

Go through the teleporter and you'll appear in the central teleportation hub. In the center, talk to the NPC Gnomette, tell her you wish to become a recruit and she will grant you access downstairs. Go downstairs and find Gnomerik at the recruitment office. Say recruitment > yes > test and answer a series of questions. After each question you continue by saying 'test' again. You need 100? points at least to pass the test.

Note: some reports suggest it is different for each player. The following combination worked at least once:

Once you have joined, go west to find Gnomespector, say 'recruit', walk south through the "g-rays" and talk to Doctor Gnomedix (with Gnomenursey). They will instruct you to walk on the examination platform next to them. Stand there and don't move while a series of server messages appear in your local chat. Once a Strange Slime spawns you can move off to the south and on to the shooting test. Ask Gnomaticus about the shooting test and he will tell you to stand on a firing platform and shoot 5 consecutive target dummies. They will appear each few seconds. You must not fire the cannon when an innocent target is on the platform ahead of you.

Once done, report back to Gnomaticus and he will tell you to go south and talk to Gnomewart for the endurance test.

Gnomewart will tell you to enter the teleport south of him and run through the one-way path to the exit. Run as fast as you can, but note that the floors can push you back and may slow you down. Once done, report back to Gnomewart about the endurance test. He will tell you to find Gnomelvis east of him at the soul melody area.

Gnomelvis will tell you to find your soul melody. To do so, use one of the four crystals in the room. You will see either red notes or fireworks. Do this until you get 7 fireworks in a row, note that for each character there is exactly 1 combination, you must find which order to use the crystals in. When you get a red musical note, you must start over.

Report back to Gnomelvis about your musical test and he will tell you that you have completed the recruitment test.
