VHAPI (Vault Hunters API, Very Happy API, etc.) is a useful mod for modifying Vault Hunters 3rd Edition.

It offers some helpful features for modders such as a custom Vault Gear and Vault Objective registry, but also allows for data loading of the following Vault Hunters config files (with varying levels of functionality):

* Skill Descriptions and Skill Gates

I highly recommend checking out the example datapack with readmes on any details and support for adding, removing, or replacing entries in configs that I have created: https://github.com/iwolfking/vhapi-example-pack

Fully compatible with Bonne's Server Config Sync mod, just include the config that needs synced in it's config file and the modified changes will be included!
