Tiers

Tiers

Storage Units, Station Units, Wireless Transceivers and Base Stations all upgrade through four rungs. They follow the same ladder the game's own crafting stations use, so each upgrade lands when you are already upgrading everything else.

Rung	Crafted at	Signature material
Base	Workstation	Logs and Iron Bar
Demonic	Demonic Workstation	Demonic Bar
Tungsten	Tungsten Workstation	Tungsten Bar
Fallen	Fallen Workstation	Upgrade Shard

All four rungs are visibly different colours, so a glance along a conduit run tells you what you have:

Storage Units

Each rung doubles the slots.

Rung	Sprite	Slots
Base		40
Demonic		80
Tungsten		160
Fallen		320

For comparison, a vanilla chest holds 40 stacks, so a base Storage Unit is one chest and a Fallen unit is eight of them in one tile.

Station Units

Each rung doubles the number of crafting stations you can install.

Rung	Sprite	Stations
Base		1
Demonic		2
Tungsten		4
Fallen		8

Wireless

The Wireless Transceiver and Base Station start at Demonic rather than base. See Reaching further for what each rung buys. They upgrade from their own panels the same way:

Upgrading an existing unit

You do not have to break a unit and lose its contents. Click a unit and its panel has an upgrade button. Upgrading in place keeps everything inside.

An upgrade costs the tier's material, and the panel tells you exactly what before you commit.

Moving a unit

The same panel has an empty button. It moves everything in that unit into the rest of the network, so you can then break the unit and put it somewhere else.

It reports what happened in chat every time, including when nothing moved, so you are never left guessing whether the button worked. If the rest of the network cannot hold everything, it moves what it can and tells you what is left.

Breaking a full unit was never destructive. Its contents drop on the floor like any chest. The empty button just saves you picking up forty stacks in a place where anyone walking past can pick them up first.
