Femboy Fantasy Tit Tacs
I really thought slamming my way through Tactics Ogre would prep me for this. I'm only like eight hours in and already I have underlevelled characters I can't do anything with. I haven't even started messing with classes yet, please help. Save me, training battles.
Also why team size so small 
EDIT: Why are black mages evil. Ranged lockon fire attack that kills you.
EDIT2: the best strat for black mages is kamakaze basically. They have a lot of range and can snap to targets freely, so running next to another enemy will result in their multi target fire killing one of their boys.
The first three battles in Tactics are a pain in the ass specifically because you only have squires/chemists. I'm not even sure if you can grind on random battles at that point - but if you can, just run around for a bit and grind using the random battles (they're green dots on the map). The 4 unit cap on battles is only for the first handful of battles.
You can do it if you've played through Tactics Ogre!!! I believe in you.
Yasumi Matsuno is bullying me
I might give it another go...
Also what version are you playing? War of the Lions or the original? If you're finding yourself stuck on it, I'll be happy to take the excuse to emulate whatever version you're playing and see if I can get you a detailed Hexfaqs strategy guide for the exact battle you're struggling with.
PS1, I am straight up not having a good time. Game is not really requiring me to grind four hours in, right?
Battle is Dortor, where you first see Weigraf.
