The Grand Master of Verbal Debate

The Grand Master of Verbal Debate is a collection of 9 volumes that can be found in around the Falcon Bastion. They teach arguments that can be used against Grand Master Oberon, and it's suspected that he could have written the books himself.
== Trivia ==
The fight against Grand Master Oberon seems to be an Allusion based on the Insult Sword Fighting of the Monkey Island Series, specially since one of the Tibia insults/answers (Volume II) is identical to a pair of the Monkey Island game.
