There is a shop in town right now, selling 15-minutes EXP berries for 10k each. There's still many on sale, but I bought a whole lot of them for the broke-ass anons or for those who miss the sale.
Also, the same shop was practically giving away 2 pieces of the same armor for Crusader, and a sword+shield for Champion. They seemed powerful, so I bought all 4, I'll give them to the respective anons.
