A lair is a type of secret area in the Warhammer Onlineworld. It could possibly be a cave, a dungeon, a mountaintop; somewhere in the zone that is far off the beaten path, and generally disregarded. What makes a lair special, is that there are no quests or directions leading you there, so they are stumbled upon by explorers who enjoy seeing every nook and cranny of the world. Lairs generally, even when discovered, require the player to solve a puzzle or figure out some indirect way of obtaining access to the lair - they also usually contain a powerful boss monster who is many times more powerful than is appropriate for the zone they are in (with a few exceptions of weaker boss monsters).
Please help. I have started to add what items drop at each Lair. A Lair will only drop a specific peice for a specific spot. Example: Chest, Hands, Feet, Weapons, etc. I have not killed them all and have only been able to fill in a few so far.
By the number of blank Tome of Knowledge entries available to us which regard lairs, we can assume there is one hidden lair in every zone. It has been stated by Mythic that there are at least more than 30, though since then they have added more and they continue to do so:
This table is a work in progress, feel free to add more lairs to the table or modify existing entries.
