Golden Helmet Quest (Ghostland)
Step 1 Down to the entrance lever
About 85 squares north-east of the New City temple go down the stairs at 31667,32267. The way leads through the stairs at 31571,32290 (floor 8), 31673,32245 (floor 9) and 31644,32292 (floor 10), through the gate of expertise at 31692,32302 (floor 11, level 90) and down the stairs at 31696,32316 (floor 11), 31674,32310 (floor 12), 31674,32307 (floor 13) and 31674,32312 (floor 14) to floor 15. From there go up the stairs at 31685,32282, pass the gate at 31686,32280 (floor 14, level 170) and climb the stairs at 31686,32278 to the lever room on floor 13.
Step 2 Five players pull the lever
Five players stand on 31685,32273, 31684,32271, 31687,32271, 31684,32269 and 31687,32269 (floor 13) and one of them pulls the lever at 31686,32273. Each player lands alone in a separate cell on floor 15. The lever then stays pulled for four hours, so only one team at a time can be inside; the lever and the !quests command tell you how long is left.
Step 3 Open your cell
Every cell has a Wladca Podziemia, a stone tile and a lever (31808,32322 - 31819,32316 - 31829,32320 - 31828,32337 - 31809,32339). Kill Wladca Podziemia, put his corpse on the stone tile within 7 minutes and pull the lever: the stalagmite in the cell wall disappears and a stone skin amulet appears. Mr. Punish, undead dragons and fire elementals live in the cells too.
Step 4 The hall of Ferumbras
From the middle of the dungeon climb the ladder at 31818,32329 to floor 14. Ferumbras, Morgaroth, Orshabaals, Minishabaals and dragon kings live in the hall. Put Ferumbras' hat on the left stone tile at 31819,32361 and the corpse of Ferumbras or of Orshabaal on the right one at 31823,32361, then pull the lever at 31821,32363 - a trapdoor opens at 31821,32366. Morgaroth's corpse does not count.
Step 5 The golden helmet
The trapdoor drops you into the room with the chest at 31820,32360 (floor 15) - the golden helmet needs level 170. The teleport at 31820,32369 takes you back in front of the level 170 gate. Four hours after a team pulls the entrance lever the dungeon closes again: the cell walls and the trapdoor come back as soon as nobody is left inside.
