About this project
What does What's Your Build add?
Introduction
Inspired by Wynncraft, this mod allows you to check other players' gear. This could be useful in Multiplayer mode, especially when the modpack is heavily gear-driven. For example, when you play on a server that installed Apotheosis, you might want to see your friend's gear because Apotheosis adds many affixes to the gear, in this case this mod can help you by simply middle clicking your friend.
Feature
- 🔍Build Viewer: allowing you to check out others' armor by middle-clicking other players. All vanilla gear will be shown on the screen.

- ⭯ Loadout system: allowing you to store and load the build file via an in-game block: Loadout Barrel(check the recipe in JEI).
The right container can be used to store your equipment. The middle-left build list allows you to create your own build; the build content will be shown in the middle-right. You can add or remove the equipment in the build without occupying the real equipment. The Wear button allows players to equip the current build by searching for the corresponding equipment in the right-side container.
Compatibility
- Curios : a new menu will be added when Curios is installed
