[Illuminated One]

Instead of linked randoms why not make the master shugenya for example 2e1n + 100%fawen and somewhat more expensive. Or even make that a copy, so the player can choose if he wants to recruit the new or the old one(s) (i.e. you could theoretically have 5 versions, giving the player the decision over his magic).
This could produce quite powerful combinations reliably while you still need to balance them against the cheaper s2 + 200%fawen mages.
