Wall of Flesh Petri Dish
This map started out as a speedrun tool for myself and a friend. We were trying to figure out how to speedrun Wall of Flesh, and realized that we weren't entirely sure what weapons and armors were best against him.
Rather than doing run after run, we decided to make a world with nearly all the possible pre-hardmode armors, accessories, items, and tools a person might want for fighting the Wall of Flesh. The world has a lot of conveniences, but the bridge is intentionally rugged, to simulate what you might actually build in the heat of a speedrun.
If you want some practice fighting WoF, for speedrun reasons or otherwise, I suggest grabbing this map. Hope you like it!
