My Inquisitor is the only person in my party with any points into magic. The other members are Ralph, a single-classed fighter, Wolgraff, a single-classed Rogue, and Bairdotr, a single-classed Ranger. None have even a single point into any magic school.

Ralph has Leadership, which grants an Initiative boost to everyone else. I might boost that up more to get Initiative 4.

Wolgraff tends to act first in battles, and my Inquisitor acts second. My Inquisitor's initiative is high because of all those points into speed - another reason for preferring Speed instead of Glass Cannon.

My Inquisitor has "Fortify" and "Absorb Elements" and the healing spells, but that's about it for defensive spells.

Will this still work later on against level 14 and level 16 enemies? I don't know. I'll let people know when I get there.
