Jiang Wei/Weapons

Here is a collection of Jiang Wei's weapons in the Warriors series.

Fourth Weapon Acquisition

 * Stage: Battle of Jie Ting
 * Requirements: Defeat Zhen Ji and Cao Zhen within a time limit (about 5 minutes).
 * Supply Team starts: Northeast of Sima Yi, moves: Northwest entry point.

Level 10 Weapon Acquisition

 * Stage: Battle of Tian Shui
 * Requirements: The main requirement to get Jiang Wei's weapon is to enter each door at Ji Castle from either from the inside or the outside alike by defeating the two guard captains. Spring both ambushes. Do exactly the same with Tian Shui Castle (and by proxy foregoing Zhuge Liang's strategy). You should gain Jiang Wei's ultimate weapon at the end of the battle after you defeat the both Yin Shang and Liang Xu. This can be done on both Free Mode and Musou Mode alike.

Level 11 Weapon Acquisition

 * Stage: Defense of Jian Ge
 * Restrictions: None
 * Requirements: Defeat all generals before Liu Shan surrenders.

Strategy: It is noted that Liu Shan can exit out past the gate, but he will only surrender if he comes into contact with any enemy generals or any active enemy entry points (and they re-spawn very often in this battle). If he's locked in front of a gate, he'll comment on he can't get out and will move to the opposite open gate, and each gate only stays closed for a small while, so time management is key. This strategy here will note on how to do everything in a more patient and stationary manner while also being near the gates to keep an eye on Liu Shan.
 * 1) Make sure you keep an eye on the gates; each gate can only be closed for a certain amount of time, but it's possible to do deal with officers in a more isolated and far-out manner than trying to keep an eye on Liu Shan, since him dealing with normal troops despite any danger messages is likely not an issue, and thus by proxy, either he's stuck with the enemies behind both the Jian Ge Gates (which he won't have much trouble with since no enemy generals will appear from there and he will flat-out ignore engaging in combat with only those troops), or he's made it past both the gates and trying to roam around the area for a key point to surrender himself. Keeping him away from both enemy generals and entry points in any way possible is key to make sure the weapon is not lost.
 * 2) For the strategy that involves preventing Liu Shan from even leaving past the gates, ring the gong at the west at the start of the stage since Liu Shan will always head there once he first appears, and ignore the east Jian Ge Gate. From there, go and kill Xu Zhu and Xu Huang very quickly, or if you want to play more patiently wait at the east gate and keep closing each one respectively till Xu Zhu and Xu Huang come to you. This will give time for when Liu Shan first appears, his time will be wasted by commenting on the closed gate and trying to move to the east gate you may have ignored. You may also instead, ignore the gate and try to take out the closest northwest enemy entry point instead.
 * 3) Liu Shan should appear by now depending on how fast you dispatched Xu Zhu and Xu Huang, and he'll comment on the closed gate. He'll move towards Zhang He and Cao Ren if you already have defeated both the first two officers and thus will move to the currently open gate, or if the both gates are already closed, he'll be stuck only for a certain while. Save before you go ahead and defeat both of them, all before Liu Shan surrenders to them. If he's moved past the gates, then try to isolate your fights away from him and you can take as much time since Liu Shan will always occupy himself with enemy peons if he happens to exit the gates.
 * 4) Liu Shan should be heading towards any open gate if you stick with the usual strategy of keeping him inside Jian Ge. Seal either respective gate he will be trying to head towards, and both gates if needed again. If he's outside, messages will frequently occur saying he's chosen a new place to surrender himself, which means he's changed destinations to any enemy entry points that are still active if any enemy officers are still taking to time to appear (if you have been getting rid of any entry points then Liu Shan will change destinations once you've done so). Act quickly to take them out, but not too much in a worry since as mentioned before Liu Shan will often be too busy with any enemy peons.
 * 5) Defeat Deng Ai and Zhong Hui once they appear. They should be easier than the other 4 usable characters.
 * 6) Go back near Liu Shan. Level 11 weapon message.

Note: Since it's tough to keep Liu Shan from surrendering, it's also recommended to use the two-player trick, with the second player keeping Liu Shan inside his fort by hitting the gong to close the door in front of Liu Shan. Either trying to keep him inside past the gates or have him take his time roaming as you isolate your fights also work the same way, but it all depends on preference and efficiency.
