Most of my characters were level 57-60, gametime around 26.5 hours.

The hardest fights in the game were in the middle and at the end. Proper grinding and preparation will get you through most of it, but the first phase of the last boss had me on the freakin ropes. I managed to use two of my characters to distract six enemies while one of my witches basically rezzed and prepped every character killed in the first 10 turns. By the time they were through my two distractions I had an army charging them again. Muhaha. The second phase had a devastating first attack, but after that I managed to get my bearings and kick his ass. FUCK U LAST BOSS.
LEVEL UP THE SAMURAI till his last skill. OMG DAMAGE!
Really fun game!
