Upgrading Guide - Dust, Materials & Respec
The Remnant Dust economy in Phantom Blade Zero: what to upgrade first, where materials come from and how the free respec window works.

Quick Answer: What Should You Upgrade First?
Both equipped weapons to level 5 — the first milestone ability is the biggest single power jump in the game (Jagged Steel's Bleed special, the Sanguine line's 20-second damage buff), and refunds are free up to level 10, so the first choice is risk-free. After that: your main boss weapon to level 10, then your Medicine (Pangzhen unlocks the upgrade), then the 15/25 milestones as materials allow. Accessories polish in parallel and unlock extra slots in the Village of Lu.
| Priority | Target | Why |
|---|---|---|
| 1 | Both weapons → Lv 5 | First milestone abilities; free refund makes this risk-free |
| 2 | Main boss weapon → Lv 10 | Falling Petal Strike-class effects multiply execution windows |
| 3 | Medicine upgrade (Pangzhen) | More charges and stronger healing for the boss marathon |
| 4 | Accessories polish | Passive damage windows (e.g. Token of Pursuit: +7% vs Guard-Broken) |
| 5 | Lv 15/25 milestones | Endgame passives and the Perfect Combo class of unlocks |
Remnant Dust Income
Dust funds every weapon upgrade, and the world pays it for curiosity: glowing scrolls, shrines, readable lore and prompted objects all grant Remnant Dust. The income habit is the same as the fragment habit — sweep each region fully before moving on, because Dust has no farm better than simply examining everything the developers placed. Materials are family-locked (a Heavy Blade line eats different metals than a Twin Blade line), which is the quiet argument for the one-one-handed-plus-one-two-handed loadout: both families' material pools stay warm.
The Upgrade Materials Map
Materials drop by region tier and family: the Scarlet Wraithblade line, for example, drinks Broadplate Metal and Solvent. Vendors sell the common tiers, bosses drop the rare ones, and the region pages list each area's crafting-relevant pickups. The upgrading rhythm that works: one full region sweep (Dust plus materials plus fragments) funds one full weapon tier — the game's pacing assumes you arrive at each region boss with the previous region's ledger cashed in.
