+**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)

+**Description of the fields**
+
+### group\_id
+
+Id of group in [spell\_group](spell_group_2130135.html#spell_group-id) table. The spell\_group may contain another spell\_groups inside, if so stacking rule needs to be defined for these groups separately.

+| 2   | SPELL\_GROUP\_STACK\_RULE\_EXCLUSIVE\_FROM\_SAME\_CASTER | Auras from group can't stack with each other when cast by same caster    |
+| 3   | SPELL\_GROUP\_STACK\_RULE\_EXCLUSIVE\_SAME\_EFFECT       | Same effects of spells will not stack, yet auras will remain on a target |
+| 4   | SPELL\_GROUP\_STACK\_RULE\_EXCLUSIVE\_HIGHEST            | Only Highest effect will remain on target                                |
