What are Large-Scale Leves!?

[Darkstride]

Eh, I've done some large-scale Battle levels and you have to kill more enemies and the enemies hit a little harder, but are still easily solo-able. They reward a lot more XP and I got a chest with 5 Amber and 5 X-Potions. A normal leve chest gave me a single Amber.

From what I've seen, you'll get more experience by doing 10 individual standard leves, but it is more time consuming. If you want a large chunk of XP up front with lesser time investment, you can do a large-scale leve.

What are they? Right now, a complete waste of time. You can do more standard leves in the same amount of time and earn higher exp rewards.

The only thing they are for right now are Amber pieces.

Pretty much this. If you have time and don't mind monotonous leve grinding over and over then by all mean, please do so.
