Smiths Flux is one of the most frequently needed crafting resources in Windrose. It serves two purposes: crafting quality metal weapons and armor from scratch, and upgrading gear you already own. Without it, your progression through mid-to-late content will stall fast. The good news is that once you know where to look, getting it is straightforward.
How to get Smithing Flux in Windrose
Smiths Flux is sold by the smugglers at Port Royal. According to Deltia's Gaming, you head to the marketplace area (marked on your map), find the vendor shown in the location screenshot, and purchase Smithing Flux for 10x Piastre per unit. Mobalytics confirms this price and adds that the item is available from Reputation Level 1, so there is no reputation grind blocking the purchase once the vendor is unlocked.
The smugglers stock more than just Smithing Flux, so Port Royal's marketplace is worth revisiting regularly as your crafting needs grow.
Piastre is the standard in-game currency, so stock up on it during normal questing and you will always have enough to grab Smithing Flux whenever you need it.

How to unlock the smugglers
Here is the part most players get stuck on. The smugglers are not available from the moment you load in. According to Deltia's Gaming, you need to progress through the main campaign first. The specific steps, based on that source, are:
- Travel to Tortuga Island.
- Take on the Underground Network quest. Completing it unlocks Tortuga and lets you upgrade your Ketch.
- Continue the quest until you receive the objective to speak with Marita, who is located inside a cave.
- After your conversation with Marita, look to her left. That is where the first smuggler vendor appears.
Once that sequence is done, the smugglers at Port Royal become accessible and you can buy Smithing Flux freely.
Do not skip the Underground Network quest expecting to find the smugglers already active. The vendors are gated behind this story progression, so there is no shortcut.
What does Smithing Flux upgrade?
According to Mobalytics, Smithing Flux is used to upgrade a substantial list of weapons and armor sets. Upgraded armor raises your defense, while upgraded weapons increase your damage output against NPCs.

The Mobalytics guide notes that Smithing Flux is available from Reputation Level 1, meaning you do not need to grind faction standing before the vendor will sell it to you. Unlocking the smugglers through the story is the only gate.
Tips for farming Piastre efficiently
Since every Smithing Flux purchase costs 10 Piastre, you will want a reliable Piastre income. Based on available information from the sources:
- Complete main campaign quests, as they are the primary Piastre source during progression.
- Return to the Port Royal marketplace regularly since the smugglers also carry other useful items alongside Smithing Flux.
- Upgrade your Ketch as part of the Underground Network quest chain, which opens further story content and income opportunities.
The smuggler vendor sells more than just Smithing Flux, so check the full inventory each visit. You may find other crafting materials worth picking up in the same trip.
