Quick answer: Upgrade your weapon with Upgrade Equipment, collect Blackstone (+10% Attack and Guard Break each), and equip attack accessories. Train Boundless Capacity to open more accessory slots.
Phantom Edge damage can be increased separately.
Upgrade your weapon with Upgrade Equipment
Weapon upgrades happen through Upgrade Equipment. It starts at the Forge in the Outpost. After you meet her there, every bell menu gains an Upgrade Equipment row, so you can upgrade at any bell from then on.
Here is how Jagged Steel (One-Handed) changes over its first two upgrades:
| Upgrade | Damage | Status Effects | Cost |
|---|---|---|---|
| Lv. 1 to Lv. 2 | 240 to 264 | 124 to 136 | The cost is 2 Forged Metal, plus 1 Solvent and 1,080 Remnant Dust. |
| Lv. 2 to Lv. 3 | 264 to 288 | 136 to 148 | You need 4 Forged Metal, 2 Solvent, and 1,620 Remnant Dust. |
Dual-wielded weapons use Twinned Metal instead of Forged Metal. The first upgrade, which comes in the tutorial, is free. You also don’t have to worry about locking yourself into a choice: Downgrade (“Revert”) gives back all of the materials and Remnant Dust you spent.
Collect Blackstone for permanent Attack and Guard Break
You can track your progress on the training screen. The Blackstone panel shows “Obtained: 0” and “Attack Power and Guard Break +0%” at the start, along with the line “A fragment that permanently increases 10% Attack and Guard Break” and a COLLECT MORE BLACKSTONE button. Both numbers go up as you collect more.
Blackstone can appear as fragments instead of a complete item. The description on a Blackstone Shard reads “Collect 4 fragments to permanently increase Attack and Guard Break by 10%.” Combine four shards to get one Blackstone. Shards are available in these regions:
- Crimson Forest
- Mandate Encampment
- Meigu Lake
- Mirage Estate
- Mountain of Imprisonment
- Pangzhen
- Village of Lu
- Weeping Creek Valley
Blackstone also unlocks abilities. Endless Renewal · Lv. 1 shows “Requires 1 Blackstone”. Collecting Blackstone also counts toward the achievement “Leave No Stone Unturned”, which asks you to “Collect 10 Blackstones”.
Equip attack accessories and unlock more slots
Open Character > Equip to manage accessories; their section sits beneath weapons, Phantom Edges, and Medicines. The ACCESSORIES grid contains six slots, with three unlocked initially and the remaining three locked.
To open the locked slots, train Boundless Capacity. Each of its four levels has the effect “Adds 1 accessory slot.” and is paid for in Remnant Dust:
| Ability | Cost |
|---|---|
 Boundless Capacity · Lv. 1 | 10,000 Remnant Dust |
 Boundless Capacity · Lv. 2 | 40,000 Remnant Dust |
 Boundless Capacity · Lv. 3 | 65,000 Remnant Dust |
 Boundless Capacity · Lv. 4 | 80,000 Remnant Dust |
Attack accessories in Weeping Creek Valley
Three attack accessories are available early, all in Weeping Creek Valley:
- Battle Wraps: “Increases damage dealt to enemies by 5%.” Nearest bell: Red Thread Barrier.
- Hunter’s Insight: “Increases damage dealt and Sha-Chi depletion against attacking enemies by 7%” Nearest bell: The Lady’s Rift.
- Token of Pursuit: “Increases damage dealt to Guard-Broken enemies by 7%.” Found in a chest near the Ruthless Archer Camp bell.

Increase Phantom Edge damage
Phantom Edges are upgraded from their own tab in Upgrade Equipment. Two accessories add more damage to them:
- Remnant Spark Cube: “Increases the damage of all Phantom Edges by 12%.” Pangzhen, near the Myst’s Tavern bell.
- Guardian Idol: “Destruction-type Phantom Edges consume 1 additional Remnant Spark and deal 75% more damage.” Mandate Encampment, near the Training Grounds Depths bell.
Set up bigger hits on Guard-Broken enemies
Guard-Broken enemies are where the big hits land. Use Standard Combos and parries to break an enemy’s Sha-Chi, then attack while it is Guard-Broken. Several accessories above, including Token of Pursuit, add damage against Guard-Broken targets.
Bleed weapons like Jagged Steel build up a Bleed Gauge. Jagged Steel’s perk, Blood Blade, “increases damage dealt and Bleed Gauge buildup rate for 5 seconds” when used on a Guard-Broken enemy, and it stacks up to 3 times. Bleed “Has no effect on Puppets, Golden Bodies, or Phantom Bodies”, so against those enemies, rely on your other damage sources.
