The Tiger Enthusiast spends all of his time hunting and searching for remnants of tigers. His hunting skills are not the best on Retribution Island. He does however possess great knowledge of the tigers and sword making. He used this knowledge to put together a magnificent sword that only him and a few people that helped him with his research know about. If you can bring him the items needs for his research, then he shall reward you too with an Infected Tiger Sword Craft Book.
