Artifacts

There are several artifacts in Idle Heroes with different colors, effects, upgrade costs and engulf values. They're graded by their colors and can be upgraded to different levels, depending on their tier. If you find a faction icon behind an effect (     ), it means, that only a hero of this faction will profit from this property.

All artifacts of a specific tier have the same upgrade cost and engulf value. Afterglow is the only exception, that cannot be upgraded. It will be generated, when you improve an artifact with a higher amount than needed (1 afterglow will be generated for every 10 extra energy put into an artifact).

## Orange artifacts

Orange artifacts are the top class of the artifact slot and they provide the highest possible stats in the game. They can be obtained in Events and in the endgame Campaign (29-1 and onwards) as fragment drops. They're very rare and expensive to upgrade.

* **Upgrade Cost**: 5400
* **Engulf Value**: 5400

There are normal and exclusive versions of this artifact tier.

### Orange exclusive versions

Exclusive versions of an artifact tier are mostly stronger than the normal version. Additionally they provide an extra property, which is only granted to a hero of the correct faction. These properties are marked with the respective faction icon.

Red artifacts provide high level properties. They're normally weaker than the orange versions but better than the green ones. They can be obtained in Events, in the endgame Campaign (Normal: 16-1 to 23-10; Exclusive: 24-1 to 28-10) as fragment drops, from the Guild Store and through the completion of 7-Star Tavern quests.
