A simple mod that provides some extra progression for single player and small private servers.
Artifacts placed on pedestals increase the difficulty value (affects maximum spawn level and loot quality).
Duplicate artifacts are not counted.
Removing an artifact from a pedestal restores the difficulty to its original value.
By default, each artifact increases the difficulty by 1.0 (max spawn levels by 30). This can be configured in the game.ini (default shown):
[ArtifactLevelBoost] DifficultyPerUniqueArtifact=1.0
The mod will notify all players when the difficulty value changes.
