I found the answer. They get that way by never doing anythig that will gain XP. This means gaining skill points by only praying to demi-gods and doing Festival Feats. They can never use Stamina or Energy so all those skill points go into attack or defence.

This would be impossible boring if this was your only character so I can only assume that they must be secondary accounts.
