DW5: Unlocking Jiang Wei
Jiang Wei isn't one of the original 6 characters that you can start off with. He, however, is easy to unlock. Just play any two Shu musou modes in order to unlock Tian Shui's prodigy. ^^
Blink
Blink is the name of Jiang Wei's fourth and best weapon in the game. In order to get it, here's what you must do:
1. Select Jiang Wei as your character and play the Battle of Tian Shui as Wei.
2. Run to the upper right corner of the map and stay within that clearing.
3. Just basically sit in one position and kill an soldiers that try to kill you. Make sure, though, that you let your morale drop until both castles (excluding the main castle) fall. At this point, the commander, Ma Zun, will begin to flee.
4. Zhuge Liang will throw an ambush at your commander in the upper right corner. Luckily, you're there so take out that ambush. The weapon box will appear once you've killed Gao Xiang.
5. Once you've killed the ambush units, your commander will be lost at this point and will decide to just charge the enemy's main camp.
6. Collect your weapon and run to save your commander. Kill Zhuge Liang in order to win the battle of Tian Shui and... Voila! You've just now retrieved Blink.
