Warriors Orochi 2 - Shu Chapter 3 - Battle of Nagashino | Diamond Treasure Guide

To get the Diamond Treasure, simply defeat Cao Xing and Hou Cheng immediately when they appear. Then just remember to get the treasure box next to Diao Chan later in the stage. This is a very defensive stage. If you play as Tadakatsu or Zhang Fei you get alot of praise from the other. no idea what happens if you're both.
