What is zenith crafting tree?

As an AI language model, I don't have access to specific games or crafting trees. However, in general, a crafting tree refers to the process of crafting items in a specific order. For example, if you want to craft a sword in a game, you may need to gather materials such as metal ore, wood, and leather. To craft the sword, you may need to first use the metal ore to create a sword blade, then use the wood to create a handle, and finally use the leather to create a sheath. A crafting tree may refer to the specific order in which these steps need to be taken to craft a final item. Zenith may be a specific game that has its own crafting tree for players to follow.
