+# DA_ObjectiveData — Data Asset
+
+**Parent Class:** `UDataAsset`
+**Dependencies:** [`BPC_ObjectiveSystem`](../07-narrative/39_BPC_ObjectiveSystem.md), [`WBP_ObjectiveDisplay`](../06-ui/WBP_ObjectiveDisplay.md)
+**Purpose:** Defines objective content — objective text, requirements, completion conditions, linked narrative flags, and reward data.

+
+## Variables / Structure
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `ObjectiveTag` | `FGameplayTag` | Unique tag for this objective |
+| `ObjectiveText` | `FText` | Display text for HUD/journal |
+| `ObjectiveCategory` | `EObjectiveCategory` | Main, Side, Hidden, Tutorial |
+| `PrerequisiteFlags` | `TArray<FGameplayTag>` | Narrative flags required before objective activates |
+| `CompletionFlags` | `TArray<FGameplayTag>` | Flags set when objective completes |
+| `bIsOptional` | `bool` | Objective can be skipped |
+| `ObjectiveLocation` | `FVector` | World location for marker |
+| `RewardItems` | `TArray<FPrimaryAssetId>` | Items granted on completion |
+| `RewardExperience` | `int32` | XP awarded |
+| `LinkedEndingWeight` | `float` | Score contribution to ending evaluation |
+
+---
+
+## Gameplay Tags
+- Namespace: `Objective.<Category>.<Name>` (e.g., `Objective.Main.FindKey`, `Objective.Side.RescueNPC`)
+
+---
+
+## Validation Rules
+- `ObjectiveTag` must be unique
+- `ObjectiveText` must not be empty
+- At least one `CompletionFlag` required (unless narrative-driven)
+
+---
+
+## Example Data
+
+| Field | Value |
+|-------|-------|
+| ObjectiveTag | `Objective.Main.EscapeHospital` |
+| ObjectiveText | "Escape the abandoned hospital" |
+| ObjectiveCategory | Main |
+| CompletionFlags | `Narrative.EscapedHospital` |
+| RewardExperience | 500 |
+
+---
+
+## Consumed By
+- [`BPC_ObjectiveSystem`](../07-narrative/39_BPC_ObjectiveSystem.md)
+- [`WBP_ObjectiveDisplay`](../06-ui/WBP_ObjectiveDisplay.md)
+- [`BPC_EndingAccumulator`](../07-narrative/BPC_EndingAccumulator.md)
+
+## Reuse Notes
+- Objectives are data-driven; no blueprint logic changes needed for new objectives
+- `PrerequisiteFlags` gate objective activation behind narrative flags
+- `LinkedEndingWeight` feeds into ending evaluation system
