What this fight tests

Whether you will commit to a heavy punish. He is slow and readable, but his swings cover enough ground that a half-committed dodge loses to them.

How to beat Jagged Steel, the Frenzied Brute

Wait for the full commitment. His recovery is long enough to fit two heavy hits if you start after the swing lands, not during the wind-up.
Break Sha-Chi rather than chipping health. A stagger here converts into a full Power Surge window.
Worth doing early even at Pathbreaker difficulty: the weapon he drops carries the first third of the game.

The loop underneath all of it is the same one every boss uses: parry the blue flash, Ghoststep the red one, drain Sha-Chi, then punish the stagger with Power Surge. Phase transitions are invulnerable — heal and reposition instead of swinging into them. And dying in a later phase restarts you at that phase, not at the beginning, so you can throw attempts at the hard half.

Location walk included. His swings are slower than they look in screenshots — worth ten seconds of your time before dismissing the detour, since the kill is the earliest guaranteed weapon upgrade in the game. — via PowerPyx on YouTube

What you get

Jagged Steel (main weapon). Drops are tied to the kill, and enemies in Phantom Blade Zero do not respawn — so a skipped encounter is a permanently missed weapon in that playthrough. If a build guide tells you to use something you have never seen, the answer is usually an optional fight you walked past.

Upgrades are refundable through reforging, so testing a new drop costs materials and time rather than permanence. See best weapons for where this one ranks.

The mistake most players make

Skipping him because he is optional. This is the earliest guaranteed weapon upgrade in the game, and skipping it makes the next three story bosses harder than they need to be.
