I'd also like to add that the Wishblade and Daedalus are extremely game-breaking, especially the Wishblade. I don't mind that Kyle and Dieck wield them in Chapter 15 at all; Caellach and Valter were supposed to be threatening bosses but were pathetic in vanilla FE8. I appreciate that you managed to make them much more competent.
However, the player's ability to obtain them merits some reconsideration. Their infinite durability and weapon stats are incredible, and they aren't even S rank weapons. Farina in particular becomes the ultimate death machine who will ORKO everything or even OHKO everything 60% of the time due to the Halberdier's innate crit and the massive 35 crit on the Wishblade. Its mt is 17, so it's just as strong as Siegmund while possessing 1-2 range and 10 more hit, not to mention self-healing abilities. That lance is ludicrous; any decent lance user such as Farina or one of the cavaliers or wyverns can simply chug a pure water and tank basically everything outside of the Creature Campaign.
Daedalus, while not as ridiculous, is also a stupidly good sword. It is the undisputed best melee sword and only faces competition from ranged swords such as the Runesword or Light Brand. Its lack of durability and awesome stats trump every other melee sword in the game. I'm not sure if it has self-healing abilities too, but even without it Daedalus is still the best 1-range sword in the game by default and will allow any decent sword user to ORKO almost everything in the game or OHKO thanks to its massive crit bonus.
I'm currently on Chapter 18, and noticed a bug regarding Hugh's weapon ranks. Despite having an S rank in both anima and dark magic upon promotion, Hugh's S rank in dark magic disappeared after chapter 17. He was using Nosferatu, and his dark magic weapon rank reverted to A after chapter 17. The same bug might also apply to Lute's promoted class.
Additionally, some description boxes and events are glitched; Karel's unit description and the flashback during the introduction to chapter 17 are such examples. I'm sure that you're already aware of them; I'm just reporting what I've seen.
Also, please don't be offended by these criticisms; I genuinely love the hack and appreciate your efforts. I may sound harsh when I don't mean to.
