Artifact Rarity

A folio of the realm

Artifact Rarity is an item property that is visible on some artifacts and meant to give players an idea of how rare the item is. Items with rarity 1 are supposed to be common while rarity 12 are extremely scarce.

In practice, the artifact rarity system is not reliable except stealable artifacts since Artifact Rarity 11 items are mostly Major Doom Artifacts which spawn many times per day.

Pre-Publish 67 Ilshenar Treasure Maps are also tagged with Artifact Rarity 0.

Stealable artifacts

For stealable artifacts, each additional point in rarity roughly means that the time it takes to spawn is twice as long.

Spawn Times

Approximate spawn times for stealable artifacts according to 1 are:

Artifact Rarity Spawn Time (+/- 20%)
1 1.5 hours
2 3 hours
3 6 hours
4 12 hours
5 1 day
6 2 days
7 4 days
8 8 days
9 16 days
10 32 days
11 64 days
12 128 days


List of Stealable Artifacts

(Note that while not stealable artifacts, the pre-existing Ilshenar treasure maps are tagged with an Artifact Rarity 0 tag with the release of the Publish 67.)
