Sima Yi/Weapons

Here is a collection of Sima Yi's weapons in the Warriors series.

Level 10 Weapon Acquisition

 * Stage: Battle of Wu Zhang Plains
 * Requirements: Defeat Ma Chao and Wei Yan.

Level 11 Weapon Acquisition

 * Stage: Battle of Mt. Qi
 * Restrictions: No bodyguards
 * Requirements: Trigger the rain event manually, instead of it activating automatically. Defeat nine of the ten enemy generals.

Strategy

 * 1) Equip Shadow Saddle.
 * 2) You will be trapped with tons of archers and mines on the ground. Fill your musou bar. Ride on the horse and go down the hill. Dismount and unleash the true musou at the archers. Get back on the horse and ride back up the hill in the same path you came down (the bombs do not regenerate). Repeat.
 * 3) Sima Yi will start cursing at Zhuge Liang when his HP goes to yellow.
 * 4) When you get about 25 KOs, suddenly it starts raining, which disarms the mines.
 * 5) The gates open, and Wei Yan rushes in with tons of troops.
 * 6) Rush outside the gate and find food (turn right when you go out). You should almost be dead by now.
 * 7) Defeat Wei Yan.
 * 8) Defeat Gao Xiang when he appears.
 * 9) Defeat Zhuge Liang, and Yue Ying who appears shortly after.
 * 10) Liao Hua, Zhang Yi, Ma Dai and Jian Yong appear one after one for the next few minutes. Kill them all.
 * 11) With about 3-7 minutes left, Jiang Wei appears. Defeat him.
 * 12) Level 11 message.
 * 13) Rush to the exit to end the stage.

Note: It's okay not to defeat Wang Ping who ambushes you when you run up the mountain. You'll still get the S-rank for the weapon. Equip the vorpal orb, elixir and the way of musou. Sima Yi's true musou can kill up to 30 troops in one shot. Officers die in two full shots if most of the lasers hit them.
