Sandustry Fluxite Upgrades Priority
Spend the first crystals on scanner, capacity, and hover — then digging speed and drone mods, not vanity weapons.
Fluxite is not Gold. Gold buys Research nodes (Shakers, belts, presses). Fluxite buys upgrades on tools, movement, and drones — the shop that makes the same factory feel twice as fast. You get Fluxite from veins, special map pockets, and the industrial loop Voidbloom → Flux Emanator → crystals below the tile (How to Get Fluxite). This page is the spend order once the first crystals are in the backpack.
First three purchases (almost always)
Community guides and beginner videos converge on the same opener:
1. Material scanner
Hover the cursor on a pixel and the scanner lists what it interacts with (wetting, burning, mixing). That is how you stop guessing whether a pile is Cinder, Burnt Slag, or Voidbloom. Linux demo users sometimes missed emoji icons; the text “Interacts with:” was added in Hotfix 7 to clarify. Buy this before you start a lava relocation project (Lava, Scoria, and Cinder).
2. Expanded grabber capacity
The Grabber starts tiny. Capacity upgrades let you pick meaningful sand, slag, and cinder piles instead of thimble scoops. This upgrade stays relevant from the first mixer through megabase cleanup. Hydro Sponge Grabber rules (surface only after Hotfix 8) still apply (Flowers and Planters).
3. Hover / movement
Post-demo movement lets Space jump and hover while airborne, which is how you build mid-air belts and traverse pixels without fighting every ledge. Lantto called demo movement the most common complaint; EA is where the rewrite shows. If hover is in the Fluxite shop on your build, take it before weapon cosmetics.
Digging speed is the usual fourth — it scales every session you spend in Sandsoil. Take it once the first three stop hurting.
After the opener
| Upgrade family | When to buy | Skip until |
|---|---|---|
| Digging speed | Right after the opener | You are still learning controls |
| Flamethrower / vacuum / cryo mods | When that tool is already unlocked in Research | You do not own the base tool |
| Rocket ammo / napalm | When you farm Cinder or open artifact walls | You still lack a press |
| Digger / Hauler drone mods | After Drones 1 (Drones) | Belts still have no gold line |
| Weapon damage | Deep combat / mystery blocks | Your bottleneck is logistics |
Drones are Fluxite-upgradeable per itch 0.0.4 notes (Diggers die on bedrock; Haulers get pickup-drop routes). Spending Fluxite on drones before Logistics 1 is how people own toys and still carry Wet Sand by hand (Research Priority).
How to fund the shop
Short path: find a Fluxite vein, buy scanner, go back to gold. Long path (the real one):
- Stable shakers + Collectors.
- Burn slag, press for gold and spores (Kinetic Slag Press).
- Wet spores → planters → Amethelis (Spores and Seeds).
- Mix RedSand → Voidbloom → emanator (Flux Emanator).
- Harvest crystals below the building — leave a shaft.
If the shop is empty, you have a supply problem, not a priority problem. If the shop is full and you still feel slow, you bought rockets before hover.
Gold vs Fluxite budgeting
Never dump both currencies into the same mental bucket. A typical hour:
- Gold → next Research node that removes the current bottleneck (belts, pipes, press, tools).
- Fluxite → scanner/capacity/hover until those three are owned, then dig speed or the tool you actually hold.
Research Checklist tracks gold nodes. This page tracks the other wallet.
Demo vs Early Access shops
The demo may cap how far the upgrade tree goes. Early Access from 2026-08-13 is where drone mods and full movement upgrades should exist as described on the store page. If a YouTube shop overlay from 2025 disagrees with your EA menu, trust the live menu (Demo vs Early Access).

Fluxite is how Sandustry stops feeling like a walking simulator. Scanner to see, capacity to grab, hover to build — then everything else is flavour on a factory that already prints.
Frequently Asked Questions
Quick answers to the most common Sandustry questions.
What should I buy first with Fluxite?
**Material scanner**, then **grabber capacity**, then **hover** (and **digging speed** fourth). Weapon mods wait until those quality-of-life upgrades are owned.
Is Fluxite the same as Gold?
No. Gold buys Research buildings and tools. Fluxite buys upgrades on tools, movement, and drones.
How do I get more Fluxite?
Mine veins early, then run Flowers → Voidbloom → Flux Emanator. Full chain on How to Get Fluxite.
Should I upgrade drones first?
Only after **Drones 1** and a working belt line. Early Fluxite is better on scanner, capacity, and hover.
Why can I not see material interactions?
Buy the **material scanner**. Hover the cursor; the tooltip lists interactions. Emoji-only icons failed for some Linux demo players — look for “Interacts with:” text.
