I just finished the Lagdau Ruins. Quite interesting. It took me about a week, of one or two floors a day. Now I have every character except Selena, who I killed, not remembering she was recruitable. Anyway, the ruins were most difficult at the middle. But after that, they got much easier. Floors eight and nine were particularly easy. How? Lots of choke points, so I just summoned dolls to get the enemies to close in, then killed them with a sniper followed up by a sage. Sophia went to super pupil, then class-changed to sage. Everything was then at 31 except defense, which was at 27. Her ability to take out Mogalls with Ivaldi was great. Of course, both lords with sacred weapons were useful too. Two dancers who can summon kept distractions up for the monsters, and the occasional healing. And three dragons with super-stones made it so I never had to use up a weapon; just use dragonstones and sacred weapons. Staves were the only things I used that took up uses.
The tenth floor was fascinating. Nine zombie-dragons, one Demon King, and one summoner. Every third turn, four to six random monsters are generated, so long as the summoner stays alive. However, the demon king drops the Sword of Seals from FE6, which is S-ranked, 18 might, CAN DOUBLE!!!!!! and you know the rest, or can look up the stats thereof. And it does have a bonus versus monsters. The zombie-dragons each dropped something very nice. Two metis tomes, two gold gems, (60,000 worth to sell each,) Naglfar, an un-promotion item, a re-promotion item, and another thing or two.
After doing that, I did chapter 20. Not too hard, actually. All the assassins spawn from the lower half. If a unit with 31 defense is put at the single choke point between the halves of the screen, nothing from the bottom can ever reach the top. Bane cannot kill, and normal attacks cannot do even one damage. Thus, my dragon was stuck with one HP, but never going down from there. The top half was relatively simple. Lyn, with stats of 31 all around, was able to charge up the middle with the Sword of Seals, criticalling Zephiel, and allowing Myrrh to rush in and kill Morva. The rest is history.
Final chapter part one looks interesting, but I have yet to actually do it. For clarification though, are the weapons on the enemies the same as the weapons in FE7? I noticed that they are not just ,ore sacred twins.
Overall, I am quite impressed with the hack. However, because I cannot read kanji, I cannot say whether the story is much different. And for me, story is a big part of a Fire Emblem. So I probably will not play this again, but it was fun for a fling.
