As promised I replayed Kenshin's Dream on Chaos. Though he is lev 50 with all skills and the 4th I really had problems because his dexterity is too low and so is attacking speed. Here is how I do it.
1. Kill Narimasa Sassa, Kazumasa Takigawa, Nagahide Niwa
2. Help Kanetsugu and defeat Toyohisa Shimazu, Nagamasa Kuroda and Kanbei Kuroda.
3. Help Shingen and defeat Hideyoshi, Hidemasa Hori, Koroku Hachisuka.
4. Help Yukimura and defeat Nene and Toshie Maeda.
5. Kill every single peon around Takeda's main camp (absolutely EVERYTHING that approaches Katsuyori)
6. Do the same around aropund Uesugi's main camp. Do not abandon your camp even if the Shimazu doubles appear and Kanetsugu asks for help. Leave your main camp only when every single enemy peon is dead.
7. Kill Toshihisa Shimazu and Tadatsune Shimaze who usually demolish the Uesugi's main camp. Kill every single peon of their troops.
8. Attack and kill Nobutada Oda before he joins real Shimazus.
9. Save Katsuyori and defend Takeda main camp. Kill both Iehisa Shimazu and Taranaga Shimazu. Somehow Katsuyori is way better than Uesigi in protecting his camp so you can leave him fighting against peons if you like.
10. Save Kanetsugu in the NW fort. Kill No and the doubles of Yoshihiro and Yoshihisa. The important thing is not to let No attack Kanetsugu onscreen as he will die very easily.
11. Now Ranmaru and Mitsuhide will show up. Both are in hyper status, but luckily they flinch. Kill Ranmaru first because Yukimura is your strongest ally and can take a lot of beating offscreen.
12. Hunt down Mitsuhide now. You may want to save because he kills me very often. Mitsuhide is better than you (Kenshin) in both reach and attacking rate. That means that he can hit you even if you were the first one to attack. In 5 fights against him I got SIX deadlocks!
13. Kill the generic first and now the real pain is to kill supercharged Yoshiro who doesn't flinch, doesn't have many peons around (meaning you don't have means to fill your musou) and can easily kill you in a single running attack. Besides both Yukimura and Shingen are most likely low on health now.
Edit1: Just found out a better way to deal with Shimazus. Do not follow step9, because Katsuyori is really good in defending the Takeda camp and also Yukimura will help him. Also it is possible to let Shingen be there. All you need to do is "escort" him (kill everything near Tsuruga castle and close the gates in the centre) to the position west of Takeda's main camp. Do not kill a gate captain there, as you want him to slow down Shingen and prevent him and Yukimura from a suicidal attack on real Shimazus in the end. The only concern is Kanetsugu, but there's not much you can do about it. Once you have cleared the NW fort and killed Ranmaru you can join Shingen, Yukimura and Katsuyori and deal with Mitsuhide, Iehisa and Taranaga and then proceed to Tsuruga with Shingen and Yukimura.
Another thing I noticed is that Nobutada attacks either you or the Uesugi's main camp and doesn't join the real Shimazus as I thought before.
Last thing is that real Yoshihisa also doesn't flinch so attacking him with square attacks is a suicide.
A bit about tactics against real Shimazus. Fight in yellow with a monk bodyguard - doble attack is very nice. The only way to deal with real Shimazus in the end is hit'n'run - attack with your musou state normal attacks and then run away and manually recharge your musou. When you recharge your musou - always keep them behind you on minimap - that way they will not refill their HP and also they won't be able to kill your allies very quickly if they attack offscreen. Juggling may seem like an option but the AI can manage to do a midair flip and then hit you with a JC that will most likely kill you if you're in yellow or red. Besides, Shingen, Yukimura and Kanetsugu will ruin all your efforts to juggle anyway.
I have decided to focus on SW2E only and started my 6th walkthrough. The previuos were with Nobunaga, Hanzo, Masamune, Hojo generic and Ieyasu. However this time I didn't start from a regional scenario, but started Divided Land on Chaos and made the worst possible mistake - chosen Musashi without even checking his rank
What was even worse I put him in North Mutsu far away from the closest shop in Owari not speaking about Chinese Trade that is possible only in the far west. Thus I had no chances of getting Awakening3
And on the top of that my neighbour had Hanzo who was FULLY maxed out beyond his limit (1000 KO medal, all the skills)
The only good thing was that I had Keiji and Kojiro as my generals both at level 20 but also without any skills aside from their initial and those gained from level ups. If only I could find another Miyamoto...
I survived and can confirm now that it is possible to beat Chaos with Musashi without practically any skills (including Awakening3), without Family Bond Musou, without lev3 musou and with first weapon. But it is really tough. The generic easily kills you in ONE hit even without Arrow formation. Getting to Owari was really challenging. Oh, and now I really hate Cavalry
I have only Kyushu to take care of now. Chaos turned into Novice after conquering Owari and visiting the shop and after finding Masamune and learning Awakening3 from him
I've learnt some new things that helped me to survive:
1. Pincer tactic. Works nearly perfectly with Musashi and Keiji against a single officer. You must not have any additional allies as they will ruin the pincer. Make sure that Keiji has a full musou (connecting lightning is present). Wait for the AI general to appear and start running to you. What happens is he enters Keiji's zone and Keiji will try to intercept him. However the AI general will ignore Keiji, because you're his priority target. If you force the AI to block with a long combo -you'll give Keiji enough time to turn and attack the AI from behind. That's the very time when you should unleash double musou. It must not be lev3 musou as your lev3 blades will ruin the pincer. The AI will block your first hit of the musou but Keiji will "unblock" him from behind
The greatest thing is that Musashi's and Keiji's musou attacks are perfectly compatible. The AI never rolls away if you start your musou in the middle of your combo -it will always try to block it.
2. Easy way to quell peasant rebelions.
The best punishers are Keiji, Yukimura and Kojiro. Guess why
They can materialise a horse with their specials and then trample those 200+ peons even faster than Kotaro with his musou or Tadakatsu with his lev3 musou
3. Nene has a unique ability to cancel and save her musou. If you use her "transform" special in your musou state - you'll turn into a peon and your musou bar will stop decreasing (as in DW games when you stop holding circle). I have yet to learn full tactical use of this.
4. The AI generals always get stuck on the Yamazaki Map in the dark blue zone in the SW of the map when they try to flee from the W to E. You can even see this onscreen as they always choose the same path that ends with the fence
It always happens, as I've replayed the map at least 7-8 times and everytime there is someone who gets stuck.
5. Musashi SpT is probably the best move in the game as it never stops to amaze me with its multiusefullness. Another thing that I found about it, is that it serves as a shield and deflects arrows. Don't know about bullets. Need to test this further.
6. Musashi's 9999 combo (lev3 musou+SpT) works beautifully with Steal tactic. The best way to get some money right in the start of the game.
7. The fences at Nagashino map actually hurt you if you're on horse. Unfortunately it's not much of the use as the cavalry tends to respawn anywhere and you can't really lure them to the fences and then roll away at the last moment. Well, maybe you can. But I don't think it is really worth the time and effort.
These are the last bits and pieces as I have decided to write a comprehensive FAQ for SW2E
It will probably take alot of time (1-2 years) but that is nothing compared to the boredom of the inifinite castle
