Getting the Bastion

Defeat Zhuo Bi, the Gatekeeper, the main story boss near the Village of Lu entrance past Old Man Gen's Hideout. It is on the boss list under Village of Lu, and the Bastion is the drop.

What it does in a fight

GamesDB's day-one numbers:

Level 1Level 60
Damage2261,559
Guard break1981,366

Every Phantom Edge multiplies its stats by 6.9 over 59 upgrades.

GamesDB names two moves for it: Reprisal Shockwave and Bolt Ward. The independent VG Times guide says what they do in practice: the Bastion acts as a shield that blocks, pushes enemies back, or slams down to create a shockwave, and it also protects against crossbow and arrow traps, so a trap corridor can be crossed safely.

The path it opens

GamesDB files the Bastion under "Opens the way", and its own Exploration list counts it among the Phantom Edges that open new paths even when you are not holding it. It is one of the keys that stops a map marker staying red — the secrets page maps the other keys to the areas they open.
