While the newly minted king of wizardly extreme Dragonlord Ken is quite a popular fellow, it never occurred in play testing. This is because I placed a limit on what IQ spells could be learned by a starting character based on where they were from.
Roll d6 1-3 Village (IQ8) 4-5 Town/Keep (IQ8, IQ9) 6 City/Castle (IQ8,IQ9,IQ10)
This allowed me as referee to control the campaign power and access to higher IQ spells. This may seem very limiting with just the HOW book, but rest assured with Magi Carta the spell lists by IQ explode in scope.
