I've been experimenting with limited cheating, and one way to do it is to give the starting charter a memorized Wish spell and enough (temporary - for this spell only) PP to cast it.
But since direct casting of Wish makes you lose 10 points from a random stat, it has a huge cost.(This is also a way you can create a Zero Wis challenger)
What Wishes would be worth the stat loss (assuming all your starting stats are at least 11 and you can't cast Wish once any stats are below that)?
Amulet of life saving, Girdle of Giant Strength, Seven League Boots... What else can be good enough to justify -10 to a stat right from the start?
