+**The \`spell\_group\_stack\_rules\` table**
+
+Table defines if auras in one spell\_group can't stack with each other.
+
+Notes: The table doesn't affect persistent area auras stacking or passive auras stacking (they can stack always) or spells belonging to same spell\_rank (they are always subject of SPELL\_GROUP\_STACK\_RULE\_EXCLUSIVE rule)

+
+### group\_id

+| 4   | SPELL\_GROUP\_STACK\_RULE\_EXCLUSIVE\_HIGHEST            | Only Highest effect will remain on target                                |
