oh...didn't notice that
For what you propose, it might be hard (you'll need a lot of xp).
(well not so hard as can be shown bellow)
however I see a nice exploit (depends on the frequency of adventurer becoming "wild"):
-upgrade all mana nodes to 1 or 2 types so that you get 4-5 nodes of each type.
get adventurer level 6 or more
-wait until it becomes adventurer.
upgrade to adept : free new promo. + free lvl 1 mana promotions
upgrade to mage : free new promo + free lvl 2 mana promotions
upgrade to archmage: free new promo + free lvl 3 mana promotions
Then : change mana nodes to 2 other mana :
wait for archmage to become an adventurer.
start the shuffling again :
+3 new free promotions + lvl1, 2, 3 of 2 more mana spheres.
re-do until satisfied
100 turns later : 4 archmages with all mana lVl 3. + many free promotions from upgrade.
then wait for becoming adventurer :
-go disciple line : (no more limitation on 4 archmage) + you can use divine III spells without upgrading over priest
then wait for becoming adventurer :
-go UBER knight-mage with many promotions !! (and free mobility I and potency if you had it for disciples..
---> would that work ?
