Talking about Spirit Magic: Bless, like iatus said, is fine, because it increases the chance to hit, but it should be combined with Heroism to inflict more damage.
I also try to get Learing to Expert as soon as possible to gain more experiance.
echo that. you want to level up your spirit magic early on.
imo Paladin, Archer, Druid, Sorcerer is the party of choice.
