+====== Artifact Buff ======
+**Artifact Buff** is a base class for artifact-related buffs in Remixed Dungeon. It extends the standard [[en:rpd:buff_mechanics|Buff]] class and adds specific behavior for artifact-sourced buffs.
+==== Description ====
+Artifact Buffs are special buffs that originate from artifact items (typically artifact rings). Unlike regular buffs, they have additional logic to track their artifact source and automatically detach if the source artifact is removed or invalid.
+==== Key Features ====
+  * **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
+==== Code Implementation ====
+```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;
+    }
+}
+```
