Terraria Assistant (RAG + Phi-3-mini)

A question-answering assistant for the game Terraria. It answers questions about crafting, items, classes, and bosses, grounding every answer in the Terraria Wiki using Retrieval-Augmented Generation (RAG).

How it works

1. Your question is matched against chunks of the Terraria Wiki using semantic search (sentence-transformers + FAISS).
2. The most relevant wiki text is passed to Phi-3-mini, which answers based only on that context. This reduces hallucination.

The repo also includes optional LoRA adapters fine-tuned on Terraria Q&A pairs (in adapters/), for use with Apple's MLX on Apple Silicon.

Requirements

• Python 3.11
• Apple Silicon Mac (for MLX)

Setup

pip install -r requirements.txt

Usage

python rag_chat.py "How do I craft a Molten Pickaxe?"

Example output: You need 20 Hellstone Bars, crafted at an Iron Anvil or Lead Anvil.

Strengths and limits

• Strong: crafting recipes, item stats, boss mechanics.
• Weaker: specific gear recommendations may occasionally be inaccurate.
• Only answers Terraria questions; off-topic questions are declined.
• Not an official source; verify important details on the wiki.
