Artifacts can be chosen in Decks section.

Artifacts are a type of mechanic released in Beta 18.0 that will affect the outcome of battles. Most of these have an effect that trigger once and on the first turn, but others take place either during the entire match or at the end of it.

You start out with the Artifacts Experience, Draw, Health, Poke, and Solidity. The rest cost gold to get:

  • 300G for a Normal Artifact
  • 1000G for a Legendary Artifact

You can get to pick up to 2 Artifacts, except if you pick an Legendary Artifact, then you can't choose a second one. There are 3 monsters that generate artifacts: Gerson, Chara, and Soulless Kris.



Onutrem tweeted on December 24, 2017 that a new mechanic will come in the next season of Ranked. On December 28, it was revealed that Artifacts was the big reveal.

People got to test Artifacts on early December 31 on the test server.
