Also Card I recommend raising Projectile Weaponry and Dex if you want to use projectile attacks (which includes ranged energy attacks). 

But I DEFINITELY recommend raising Mike's Vit big time. Otherwise he will be dead the moment any Imp happens to score a max damage hit on him. Vit is probably the most important Stat ever in the history of ever. Sure stats for attacking (whether with magic or melee) are good and all, but that HP and Resilience are two good things to have.
