Highlander Class

Unlockable for Classic Mode after beating the Story Mode, this class belongs to the Main Character. Hero-type class which benefits from being on the frontlines - a majority of the Highlander's passives kick in when it gets hurt, so it's more of a Berserker-type class with control. They use mainly spears, and are physically oriented. The Highlander's stats are balanced, but slightly lower than average TEC and LUC.

^ Eh, Peerless Stance seems to make it pretty simply.
Super-buff -> Go nuts.

Except how will you afford it? Grimoires may be fancy, to sort it out.

^ They can just decide that it doesn't count. Zeroth rule. But it's likely.

[Reynard-Miri]

I know it's wishful thinking, but I'm hoping that the stances are states instead of buffs. Didn't they do something similar for Arcanist circles in EO4?

[noodles]

Wishful thinking? The game's already out in Japan, so all the stuff is more or less confirmed, right?

[Riseatrance]

The issue is that stances are treated as buffs. So that's a wrap.

Yes, I have verified they do take up a buff slot.
