Quick Answer: What Do Weapon Upgrade Levels Unlock?
Every five upgrade levels — 5, 10, 15 and 25 — a weapon or Phantom Edge gains a new passive or active ability, and these abilities are where builds actually come from. Combat runs on only two attack buttons, but the depth lives in these unlocks: Jagged Steel's level-5 special applies massive Bleed buildup on Guard-Broken enemies, the Sanguine line's level-5 is a 20-second damage buff, and the Scarlet Wraithblade's level-10 Hidden Thorns boosts explosion damage and Sha-Chi depletion.
| Weapon | Level | Ability |
|---|---|---|
| Wooden Sanguine | 5 | Back to Basics — parries drain more enemy Sha-Chi |
| Wooden Sanguine | 10 | Falling Petal Strike — more damage to Guard-Broken enemies |
| Wooden Sanguine | 15 | A Light Touch — a Perfect Dodge restores some Sha-Chi |
| Wooden Sanguine | 25 | Perfect Combo — timed button press after an attack executes a stronger string |
| Jagged Steel | 5 | Special attack with massive Bleed buildup on Guard-Broken enemies |
| Sanguine / Sanguine Twin | 5 | 20-second weapon buff that greatly increases damage |
| Scarlet Wraithblade | 10 | Hidden Thorns — more explosion damage and Sha-Chi depletion |
| Dread Axe | 5 | Double-tap R2 plus two Remnant Sparks: an instant fully charged strike |
| Hunter's Chain Sickle | — | Combo-ender that yanks enemies toward you |
The Upgrade Economy: Dust, Materials and Free Refunds
Upgrades consume Remnant Dust (the universal currency — investigating lore objects, scrolls and shrines is the passive income stream) plus per-family materials, and each weapon family banks its own: Broadplate Metal and Solvent for the Scarlet Wraithblade line, for example. The respec rule is generous: reverting to level 10 refunds everything free; reverting past 10 and again past 20 costs a reforge talisman — plentiful consumables that make experimentation functionally free. Phantom Edges and standard weapons use different talisman types, so keep both stacks.
Which Milestones Matter Most
Priority order for most builds: first, both equipped weapons to level 5 (the first ability is usually the biggest single jump — Jagged Steel's Bleed special and the Sanguine buff are the two famous ones). Second, your main boss weapon to 10 (Falling Petal Strike-class effects multiply your execution windows). Level 15 and 25 abilities are endgame sweetness — real, but the first two tiers carry any run. And because refunds are free to 10, there is no wrong first candidate: level what you actually swing.
