Archmage to Hero lost anout 100 spell points, but gained them back very quickly.Champion to Master Archer lost about 250 HP but with BDJ's Helm got them back (and then some)
Spy to Champion gained about 150 HP, but did not have any spell points since I did not give him any magic as I had planned to convert him to Chamnpion ao figured it would be a waste of money and Skill Points.
Priest of Light to Master Archer did not lose any spell points but gained about 75 HP.
Here's a couple of examples of how tough this team is: I cleared Barrow Downs COMPLETELT in 1 ame day . . nothing moving and no red spots anywhere. I did not use invisibility at all even when I was teleported (from the chest) into the midst of all those spiders near the castle. They never stood a chance!!! I cleared out the Unholy Alliance Army and never took a healing or mana potion the whole time!
Like I said, these guys and gals are uber-tough.
