Warrior general abilities asides from the one where you get more slots on the army are completely useless while the mage general damage spells are extremely overpowered.
Not completely useless. The melee general should get better static atk/def buffs as it levels though. I’d guess that’s a bug.
Starting with Ranger Flare + Maneuver is very good and it picks up some decent stuff later.
Main thing is buying your army from Irabeth at the beginning.
The last general I recruited was a mage, and her battles are just absurdly easier than any of the others. Fighter’s units have better statlines, but just can’t compare to deleting massive swathes of enemies before they even get stuck in.
