OK heres how to unlock all the CAW outfits, I know Da Qiao Forever has already breifly explained it and wonderpeirrot told us about it but I'll make this little guide here just to Help you guys out.
A few things to note:
- I recommend playing in officer mode rather than ruler just because in some respects its easier.
- You do not have to play as a CAW character to unlock outfits.
- Whilst the escort Cai Wenji Mercenary mission will give you outfits there are other Mercenary missions that may net you them (ie. Tiger/Wolf missions) these for me were open alot earlier than the escort missions.
- You don't actually find out if the Treasure you obtained in a battle is an outfit piece or just a bonus treasure (ie. Rare Gem) til after the battle so its sometimes just luck.
Trick to obtaining them:
1 - When you recieve a Treasure during a Mercenary mission, Just before your about to complete it SAVE to FILE A
2 - When the mission ends and you have recieved your outfit piece, SAVE the game to FILE B
3 - Then once saved LOAD FILE A
4 - Finnish the mission again and recieve your next outfit piece
5 - SAVE the game to FILE B then repeat from step 3 until you have all Outfit pieces.
Obtaining The Last Two Armours:
To obtain the Knight/Unicorn outfits you need to complete the game, You can use the trick above so that once your about to finnish the last battle, SAVE to FILE A then after the movie sequence the game will ask you to save, so SAVE to FILE B. Then just reload FILE A and complete the last stage again, This way you don't have to go through the whole game again just to unlock the second armour.
I hope this helps you guys out!
