Artifact Buff is a base class for artifact-related buffs in Remixed Dungeon. It extends the standard Buff class and adds specific behavior for artifact-sourced buffs.

• Source Tracking: Each ArtifactBuff tracks its source entity ID via `getSourceId()`
• Auto-Detach: If the source ID is `EntityIdSource.INVALID_ID` (meaning non-artifact source), the buff automatically detaches
• Persistence: Artifact buffs with valid source IDs don't get packed/saved with the game state (`dontPack()` returns `true`)
• Entity Kind: Returns “artifactBuff” + parent entity kind for unique identification

```java public class ArtifactBuff extends Buff {

  @Override
  public boolean act() {
      if(getSourceId()==EntityIdSource.INVALID_ID) { // non-artifact source
          detach();
      }
      return super.act();
  }

  public String getEntityKind() {
      return "artifactBuff" + super.getEntityKind();
  }

  @Override
  public boolean dontPack() {
      return getSourceId()!= EntityIdSource.INVALID_ID;
  }

} ```
