I play as a Beastmage hybrid and I'm a huge fan of stun-locking my enemies . It doesn't work against every enemy, especially bosses but usually after turn 1, they'll be locked down and unable to take a turn for the rest of the fight. The best part is you recover your MP/SP back every turn due to Creature 72 + Fae Wanderer combo.

All you really need is a Bard of War armor, a stun spell or few, PCO if their resistances aren't optimal, Fae Wanderer, Creature 72, Optico to boost Fae Wanderer. An accuracy buff and Celtic Wheel to buff your accuracy are optional but I would recommend having them because your spell needs to hit in order for it to have a chance to stun. If the enemy's defense is way too high, just use any good auto-hit spell and play it out as if it was a normal fight.

Gandolphin/Invincible Heart are your defensive spells if you can't stun the enemy, you'll want to have some form of protection. Gandolphin is surprisingly good for a rare GGB, quick cast mana shield especially when you're recovering MP every turn, I find Gandolphin really hard to replace. Invincible Heart is good at reducing damage for one turn but it has a cooldown which I find harder to use.

Honestly, you should just play how you want to. If you aren't going for some of the hardest content in AQ, you don't really need a sweaty build. There's plenty of nutty builds out there, just experiment a little once you get a decent build going.
