Aura Progression in Sandustry

Aura progression begins after the Auralite milestone and advances as you mine Crystal. You can remove the Aura Extractor after crystallization starts; its crystals enter a buffer and are released as Auralite after the Extractor is rebuilt.

Quick answer

Enter your current Crystal count to see your Aura radius, next research threshold and how much Crystal you still need. Aura starts at a 64 px radius and reaches its maximum 320 px radius at 10,000 Crystal progress.

How Aura progression works

  1. 01

    Reach the Auralite milestone

    Produce the required Auralite and move into the Aura stage.

    ↓

  2. 02

    Use the Aura Extractor

    Begin the Crystal / Aura progression. You may remove it after crystallization starts; buffered crystals return as Auralite when the Extractor is built again.

    ↓

  3. 03

    Mine Crystal

    Crystal progress increases the usable Aura radius.

    ↓

  4. 04

    Reach research thresholds

    Specific Crystal milestones make later Aura and Swarm research available.

How to increase Aura

Increase your Aura progression by mining more Crystal. Aura radius follows Crystal progress rather than increasing in fixed equal steps.

Primary

Mine more Crystal

Crystal mined is the main Aura progress source.

Common Aura questions

How do you increase Aura in Sandustry?+

Mine more Crystal. Aura radius follows Crystal progress rather than increasing in fixed equal steps, and later research unlocks at specific Crystal thresholds.

How much Crystal do I need for Prismite Well?+

Prismite Well unlocks at roughly 1,407 Crystal progress.

What is the maximum Aura radius?+

The maximum Aura radius is 320 px at 10,000 Crystal progress.

When does Prismaline Well unlock?+

Prismaline Well is tied to the 10,000 Crystal milestone.

Why can't I place a Prismite Well?+

Prismite Well must sit in the valid outer Aura zone, not directly beside the Aura Extractor. Move farther out while staying inside the Aura range.

Can I move an Aura Extractor after crystallization starts?+

Yes. Removing it stores the existing crystals in a buffer; after you rebuild the Aura Extractor, that buffer is released as Auralite.
