The Raven King's Crypt Quest
Step 1 Walk to Ravenhold
There is no ship to Ravenhold. From Thais walk north-west to the rocky coast and take the stairs at 32208,32100 down into the tunnel under the sea, pass the level 50 gate and climb the stairs at the end onto the island's eastern shore. Follow the road west to the ruined castle and go down the stairs in the central hall of the keep at 32055,32114.
Step 2 Down to floor 11
Bring a rope. On floor 8 drop into the hole at 32073,32185, on floor 9 into the hole at 32099,32145 and on floor 10 into the hole at 32019,32124. Below every hole is a rope spot, so you can always climb back. Dragons and dragon lords, then behemoths and demons on the way.
Step 3 Into the crypt
Floor 11 belongs to Orshabaals and Morgaroths. Drop into the hole at 32058,32183 to floor 12, follow the cave north and pass the gate of expertise at 32055,32167 (level 200). Behind it lies the Great Hall: three Orshabaals, two Morgaroths and demons, with more demons in the side corridors.
Step 4 Break all four seals
Four chambers each hold a lever - a seal. West of the hall, the Chamber of Flame (two Infernals, hellhounds, hellfire fighters): lever at 32013,32158. North of it, the Chamber of Shadows (Ghazbaran, dark torturers, hands of cursed fate): lever at 32018,32131. East of the hall, the Chamber of Bone (two Morgaroths, undead dragons, blightwalkers): lever at 32097,32158. North of it, the Chamber of Blood (an Orshabaal, a Morgaroth, furies, plaguesmiths): lever at 32092,32131. On top of that, a Ghazbaran and a Morgaroth stand right next to every lever. Every character has to pull all four levers personally; a team goes in together, but each member pulls them.
Step 5 The vault
North of the hall a juggernaut stands in the corridor, and two Ghazbarans and three juggernauts guard the antechamber. The door at 32055,32130 opens only for a character who has broken all four seals. The chest at 32055,32124 (from level 200) holds two annihilation removers - once per character.
