+ * Return God's Sword's separate Light-damage rider for one qualifying event.
+ *
+ * Current CoA describes God's Sword (491621) as a Knight/Rogue passive whose
+ * offensive physical abilities inflict 350% offhand weapon DPS Light damage
+ * with high aggro generation. The helper models only that documented damage;
+ * it does not invent an aggro multiplier or decide how callers divide
+ * multi-hit, channel, or area actions into damage events.
+ *
+ * The explicit patch chain identifies this as the same reworked ability:
+ * 10.6.1 made it an active offhand-DPS physical rider, 11.1.5 changed its
+ * damage to 350% Light, and 12.1.0 made it passive.
+ *
