I am now at the 12 hour mark and I am just barely about to start Chapter 15. I know I should be further, but two things happend that just screamed, "EXPLOIT GAME HERE!!!"
1) During Chapter 12 (I am playing Ephriam's Route), I noticed there was a Arena there that I could train my guys in, and on top of it, if it looked like I was going to lose, I could just back out at the price of 700 gold or something. I ended up coming out with 3 characters promoted after level 20 (Joshua to Swordmaster, Forde to Paladin, and Kyle to Great Knight), Marisa at level 12, Ewan to Level 10 so he could promote at the begining of the next level to Shaman, and a spare 30,000 Gold in my pocket. That level alone took me about an hour and a half without the animations on and if I didn't grind, probably would of only took me 20 minutes. For me, that was the hardest level thus far, then again, I have heard 15 is exactly very fun either xD.
2) During the last chapter (Chapter 14), I recruited Rennac and gained access to the Secret Shop. With about 40,000 or so in my hand, I knew I could buy about 4 extra promotion items to get some of my units up to there next respective classes. All I had left was the Boss (Which was a big General with a huge sume of health), and after looking at the stats, I realized I could us Ewan to hit the boss and as long as I got him out of there before his turn (By rescuing him with another character), I could just gain experince endlessly since Ewan didn't even do enough Damage to even phase the guy. He would just recover that damaga on the next turn and while doing this with Ewan (I think he was at level 19 or something at that point), I realized the Boss hadn't even attacked me back. I checked the Boss's Stats and it turns out I had broken his only weapon because he had hit Ewan so many times xD. After having a good laught and a few double takes just to be sure, was only left with a smile. 2 hours later, Ewan is a Druid, Marisa is a Assassin, Ross is a Berserker, Cormag is a Wyvern Lord, Tana is a FalcoKnight, and everyone else on my team who is unpromoted is at level 16 or higher. I would of kept going, but Gerik pulled a 1% chance Critical Hit out of nowhere and killed the boss. I guess it's what I get for trying to exploit the game. It got to the point where the game wanted me to just stop xD.
I know the next level is supposed to be challanging, but I am worried it might be to easy most of my units are way stronger then they should be at this point. I didn't even struggle with Chapter 14 (Beat it on my First Try), and a lot of people said they really didn't like that chapter at all.
