Book of Truth?

The Book of Truth? is an attempt by evil forces to create and distribute a corrupted version of the real one. To acquire this book had to slay monsters in the anti-virtue dungeons. The more monsters you slay, the greater your chances of receiving a book on their corpse. You also had a better chance with creature's of high fame. For this reason, the drop rate is 2x better in Felucca due to the double-fame bonus. You don't have to have any quest to get a book.

When a book dropped on the monster corpse you heard a distinct flute noise. No other indication is given that the monster dropped the book and all players can hear the noise. Books of Truth? can be insured, sent to the bank with a Bag of Sending, or toggled quest item to be unlootable by other players when you die.

The books stopped spawning on March 15, 2007.

Dungeons

The books spawned in the anti-virtue dungeons on both facets.

Rewards

The books are an item to be turned in for one of 4 quests located in the Lycaeum, north of Moonglow. Visit one of the Seekers of Truth near the teleporters. Each quest, except for Veracity's quest, can only be completed one time per character. Veracity's quest can be completed as many times as you would like. Also, you can not take on multiple Book of Truth collecting quests at the same time.

Although this is supposed to be a limited time event, the developers have stated all rewards will be available by some means in the future.

Updates

The nether energy suffusing the dungeons has begun to fade, reducing the dispelling abilities of affected dungeon creatures somewhat.
Creatures in Wind will no longer drop Books of Truth (Wind is not a Dungeon of Anti-Virtue and was not intended to be included)
Increased the drop sound radius from 8 to 12 tiles
The Book of Truth drop rate in Felucca has been decreased slightly to account for the increased fame given by monsters on that facet. (The drop rate was 260%, it is now 200%)
