DarkRiftEventTaskData.xml defines Dark Rift event task sequences: task categories containing ordered steps, each with NPC group spawn assignments that execute during rift encounters.
SpawnPointId as index: NPC groups within a step are indexed by spawnPointId, not by npcGroupTemplateId. The create command writes spawnPointId to the element; a separate update writes npcGroupTemplateId.
Step ordering: Steps execute in step number order. Ensure step numbers are sequential within each category.
Category references: The id of an EventTaskCategory is referenced by DarkRiftData entries via the eventTaskCategoryId attribute.
Singleton entity: Uses SingleFile organization. The darkRiftEventTaskDataId is for DSL operations only.
