Forge keeps four Solvent in the bucket right beside him at the Weeping Creek Valley Outpost in Phantom Blade Zero, and they’re easy to walk past on your first visit. Solvent is the upgrade material every main weapon shares up to level 10, and the valley’s other pickups come in threes, starting with the clearing where you beat the Thorn Brute. The Phantom Blade Zero Weeping Creek Valley map around the Outpost forge pins each one.

Each pickup here was collected on PS5 for Map Master, and the Phantom Blade Zero weapon upgrade wiki and region maps follow Soul’s other materials. Pickups grow by region, from threes in the valley to sixes and eights in Crimson Forest, twelves in the Village of Lu, and seventeens and eighteens in the Mandate Encampment.
Every weapon type draws on the same Solvent, while each type takes its own metal, so two blades of different types split your metal but share one Solvent supply. Going from level 1 to 3 is reported to cost 3 Solvent, level 4 another 2, and the step from 9 to 10 is reported to need 4, so the bill climbs as you near level 10.
Past level 10, Solvent hands over to stronger tiers. The Concentrated Solvent that takes over past level 10 covers the refined levels, and Universal Solvent is reported for the very top, so regular Solvent is only for a weapon’s first ten levels. That makes it the material to spend freely early on.
The Thorn Brute clearing’s three are on your route, near the rocks where the mandatory fight happens, and they’re reported to cover a blade’s climb to level 3 but not level 4. More threes wait on the lower roof west of the Outpost Courtyard Bell, inside the house east of the Outpost Bell, and by a shelf in the demolished house, all near Forge, the blacksmith beside the Solvent bucket.
One valley three hangs in a bag in a bamboo tree, and only the Feather Bow can shoot it down, so it waits until you finish the Purge the Sect Tale that earns the Feather Bow. The Valley Sha-Chi Tower adds two more threes, one at the end of the central pipe on the Tower Base’s third floor once the Powderkegs are dealt with.
Most forest pickups are eights: near the Crank Slot, in the cave you search for Quick Hand Zhang’s crank, and by the dumps halfway down the ramp. A chest of six waits at the end of the clearing north of the Mirrorwood Lóng Pillar through the southern Mirrorwood Cave Entrance, and the Phantom Blade Zero Crimson Forest map with the Mirrorwood Lóng Pillar places them all.
A seven waits by the wooden cages on the upper side of the Thieves’ Camp Dungeon cave, the same spot where a crossbow trap needs Bastion’s Bolt Ward, so it may need a return trip. Another seven is on top of a wooden platform, and each forest eight is more than two valley threes put together.
The Village of Lu’s Solvent comes in twelves, including one inside Quick Hand Zhang’s hideout through the entrance by the waterfall. The Phantom Blade Zero Village of Lu map by the waterfall places them, so Solvent won’t be what stalls a fresh boss drop here.
Pangzhen’s pickups are eights, and the Mandate Encampment’s run to seventeen and eighteen, the biggest Solvent pickups on the map. The Phantom Blade Zero Pangzhen & Mirage Estate map around the Green Serpent House and the Phantom Blade Zero Mandate Encampment map behind the Outer Gate pin them for any second or third blade you’re still raising.
The valley Peddler sells twelve Solvent at 832 Remnant Dust each, so one valley pickup of three spares you 2,496 Dust and a full shelf costs 9,984. The Peddler’s Solvent shelf and its prices only makes sense if a boss is blocking you and your main weapon is short.
Spend Solvent on your main weapon first. Levels under 10 are reported to refund for free, Solvent included, so testing a new blade costs nothing in the long run, and Crimson Forest’s eights arrive soon enough that saving it in the valley rarely helps.
