Glossary

Short definitions of the terms the tools use.

No login

Short definitions of the terms used across these Illuvium tools, in our own words. They are based on the descriptions Illuvium publishes in its item collections and on the traits of the items we read from Immutable's public API on 1 November 2026. Rules of play that we could not verify from those sources are left out on purpose.

Terms 23

Illuvial

The core creatures of Illuvium, each with unique abilities and characteristics. The collection says players capture, fuse, level and battle with them across Overworld and Arena.

Overworld

The Illuvium game named in the Illuvials collection description as the place where Illuvials are captured.

Arena

The Illuvium game named in the Illuvials collection description, together with Overworld, as a place where Illuvials battle.

Zero

The companion game to Illuvium, according to the Land collection description. Land plots generate FUEL in it and Blueprints are researched in it.

Beyond

The tag the Illuvitars collection carries in its Compatible trait. Its items are the hand-drawn Illuvitar portraits.

Line

The family an Illuvial or Illuvitar belongs to, such as Mammoth or Red Panda, stored in the Line trait.

Affinity

An element-like trait of an Illuvial. Common values seen on 1 November 2026: Air, Earth, Fire, Nature and Water. Mixed values such as Tempest, Mud, Magma, Wildfire, Inferno, Bloom, Shock, Steam, Spore, Granite, Toxic, Dust, Tsunami, Frost and Verdant also exist, and some tokens have none.

Class

A role trait of an Illuvial. Values seen: Aegis, Arcanite, Behemoth, Berserker, Bulwark, Colossus, Empath, Enchanter, Fighter, Harbinger, Invoker, Mystic, Phantom, Predator, Psion, Revenant, Rogue, Slayer, Templar and Vanguard.

Stage

How far an Illuvial line has developed. The sample showed stages 1, 2 and 3.

Tier

A rank number. Illuvials and Illuvitars showed tiers 0 to 5. Land plots are tier 1 to 5, and higher tier plots have more elements and fuel sites.

Finish

The look of an Illuvial or Illuvitar. Values seen: Colour, Holo and DarkHolo.

Total power

A number stored on Illuvials and Illuvitars. On the Illuvial we checked it equals the sum of its six stat traits: health, attack damage, attack speed, movement speed, omega power and resistance.

Illuvitar

Hand-drawn profile pictures used in the Illuvium Universe, collected in an Illuvitars Album and customised with Accessories, according to the collection description.

Land

Plots in the Illuvium Universe. There are 100,000, from tier 1 to tier 5. They generate FUEL in Illuvium Zero. Regions seen include Halcyon Sea, Abyssal Basin, Crystal Shores and Shardbluff Labyrinth.

FUEL

What Land plots generate in Illuvium Zero, according to the Land collection description. The Fuels trait of a plot is a count of its fuel sites.

Landmark

A special feature of some plots. Values seen: Eternal Spring, Primeval Marsh, Halogenic Geode, Pegmatite Swarm, Dimensional Anchor and Fallen Star. Most plots have none.

Blueprint

Researched in Illuvium Zero and used to craft unique Skins, according to the collection description. Each names the Illuvial line, stage and path it belongs to.

D1SK

An item that stores valuable Illuvium data such as Illuvitars or Emotes. Loading a D1SK mints the assets inside, according to the collection description.

Immutable zkEVM

The blockchain the item collections of this hub live on. Sales there are paid in ETH, USDC or IMX.

Listing

An item offered for sale at a price set by its owner. The cheapest listing is what a seller asks, not what the item is worth.

Sale

A completed purchase. Our sales pages show the price per item the buyer paid, fees included.

Stackable item (ERC1155)

An item type where one token id can have many copies, like Blueprints and D1SKs. One listing can sell several copies.

ILV

The Illuvium token. It is an Ethereum token, see the ILV token page.

Sources

Terms about items quote or paraphrase the collection descriptions on Immutable zkEVM. Value lists (affinities, classes, tiers, finishes, regions, landmarks) are the values we saw in a sample of several hundred tokens per collection on 1 November 2026, so a rare value may be missing. Terms about market figures explain how this site computes them, see the market overview.

FAQ

Why are there no rules of play here?

We could not verify the current rules from a source we can read, and the status of each game changes. The glossary sticks to what the item collections and their data say.

Where do the definitions come from?

From the collection descriptions and token traits read from Immutable's public API on 1 November 2026, and our own plain wording of them.
