Artifacts are used to power-up your stats so it is easier to reach farther stages in Adventure Mode and complete Time Challenges. They won't affect Gates of Gog.
Normal artifacts can be Common, Uncommon, Rare, Epic or Legendary.
The rarity is determined by the kind of bonuses an artifact has: a Common artifact, for example, can only have non-cappable bonuses in it. Some bonuses will only appear in Epic and Legendary artifacts.
There are a total of 40 (last update) artifact slots in the game. You start with 4 slots unlocked, but you can use Gems to buy additional Artifact slots. Need 7020 gems to open all artifacts.
Each artifact is attributed a certain amount of level. The level amount is based off what stats the artifact has rolled: an already existing Artifact can be upgrade to increase its level and the bonuses it gives.
The cost of upgrade an artifact can be decreases by unique bonuses from Artifact.
Players start with a max level of 200 per artifact. This can be increased later with Mythical Artifacts.
