How to Reach the Mandate Encampment in Phantom Blade Zero

In Phantom Blade Zero, the Mandate Encampment is entered from the eastern side near the Village of Lu, but its gate is locked until you progress the campaign to Pangzhen and defeat Gu Wanyue, the Wailing Wraith, then drop down the well to grab the Mandate Encampment Gate Key. The zone includes the Cliffside Walkway and the Training Grounds, where a boss drops the Bashpole, a Phantom Edge weapon that smashes floorboards to reveal hidden chests. Other bosses drop the Soft Snake Sword for parrying and start a side quest collecting discarded hero relics that rewards a Soul Temper material.
