Goddess of Victory: NIKKE and LLM Limitations: Domain Hallucination in Gaming Mechanics

Key Insight

Without structured domain data, generic LLMs fail to validate strict state-machine constraints (such as 20s vs 40s Burst I-II-III skill chains), producing convincing yet completely unplayable team compositions via Domain Hallucination.

1. Hallucination Patterns in Tactical Gaming

[Typical LLM Hallucinations in NIKKE Team Compositions]
1. Burst Chain Collapse : Recommending a single 40s Burst I ➔ Stalls skill cycle permanently
2. Role Inversion       : Labeling pure defensive units as 'main hyper-carries'
3. Sycophantic Validation: Inventing false synergies to validate unviable SR character setups

2. Root Cause: Lack of Deterministic Rule Engines

Next-token predictors lack state-machine validation engines. They mimic gaming jargon without computing mathematical cooldown loops.

3. Solution: Structured Metadata RAG & Deterministic Validators

• Inject character cooldown tables and weapon burst generation rates via structured JSON contexts.
• Implement deterministic backend code checks ([Burst I: 20s] + [Burst II: 20s] + [Burst III: x2]) before invoking LLM commentary.
