Shadowless Edge.

Sanguine Twin in its Soul Tempered state: twin short blades that conjure a duplicate to fight alongside Soul. Its active art transforms him into a black crow, sweeping across the arena in a way no guard can stop.

Key points

Shadowless Edge at a Glance

  • Made by tempering Sanguine Twin. Nothing lies waiting in the world for you to pick up. Once the needed materials are in your hands, Soul Tempering Sanguine Twin produces it.
  • Collect two fragments. One Chaos Iron fragment is dropped by a Long Pillar inside the Phantom Illusionist Ruins, and the other by Yucong, an optional boss.
  • A duplicate equal to Soul. Shadow Form conjures a copy whose Attack and Guard Break equal Soul's, and which attacks whatever he is targeting before anything else.
  • Summoning has a cooldown. Once a double disappears, a delay must pass before the next appears, so a careless summon can leave you fighting by yourself.
  • Crow sweep that cannot be blocked. Phantom Requiem sends Soul racing ahead in crow form, and works best when the double is already keeping the enemy busy.

Overview

When Soul Tempering finishes, Sanguine Twin turns into Shadowless Edge, short blades that put a second body next to Soul in battle.

Sanguine Twin relies on the sheer quickness of a single combatant. Shadowless Edge reshapes the encounter instead: two fighters face the enemy, one holding it in place while the other delivers the finish, and Soul also gains an unblockable means of crossing the arena. Among the tempered forms of this weapon, it is the one built on summoning, while Infernal Rouge centres on revival and Blazing Edge on fire.

How to Obtain

Before you start:

  • Own Sanguine Twin
  • Have already encountered Myst in Pangzhen
  • The four Acolyte Masks and the Dread Axe in your possession
  • Blazing Edge, needed against Yucong
  1. Sanguine Twin can be taken from a weapon rack standing right after Yu'er, deep in Weeping Creek Valley.
  2. Soul Tempering becomes available after you speak with Myst at her tavern in Pangzhen.
  3. Gather every one of the four Acolyte Masks, then step through the Four Guardians’ Mirror, found in the icy northwest corner of Meigu Lake, into the Phantom Illusionist Ruins. Use the Dread Axe to smash the barrier after the third Bell, and beat the Long Pillar there to receive Chaos Iron Fragment I.
  4. Once Mirage Estate has been reached, pursue the Triple-Threat tale to the Mirrorwood in Crimson Forest and beat Yucong, who holds the remaining Chaos fragment. Blazing Edge is required for this encounter, so temper Sanguine Reach beforehand.
  5. Soul Temper Sanguine Twin using Chaos Twin Daggers ×1 plus 5,000 Remnant Dust. Shadowless Edge is what the pair is reforged into.

How It Plays

The double from Shadow Form

Shadow Form conjures a duplicate of Soul with Attack and Guard Break matching his. It focuses on the same enemy Soul is hitting, then chooses a target by itself when he breaks off, so pressure builds without any commands from you.

After the double disappears, a delay precedes the next summon. Pick your moment so that this gap does not catch you alone against a dangerous enemy that is concentrating entirely on you.

Using Phantom Requiem on a pinned enemy

This active art costs a single Sha-Chi point and breaks Soul into a black crow, which streaks forward over the arena. Blocking it is impossible and stopping it head-on is extremely difficult. Fire it off just as the double has the enemy tied down.

Upgrade Paths and Versions

Soul Tempering

Each weapon permits only one Soul Tempering, with a material unique to it. For this recipe, the pieces to gather are the two Chaos Iron fragments.

Pros, Cons and Ideal Situations

Strengths

  • Since the double shares Soul's Attack and Guard Break, it applies genuine pressure and is no mere decoy.
  • Its first choice of target is whatever Soul is hitting, so one body can hold the enemy while its partner ends the fight.
  • Because Phantom Requiem cannot be blocked and moves across the arena, it can reach an enemy that the double is already holding in place.

Weaknesses

  • A delay follows the loss of a double before you may summon again, and rushing the summon throws the art away.
  • With the double gone, you are a lone short-blade fighter absorbing every attack.

Best used for

  • Extended duels in which a second attacker splits a boss's focus.
  • Hitting with Phantom Requiem as the double keeps the enemy pinned.
