This is for use in the Wold's Vaults modpack, but it will work as long as you have the pre-requisite mods.
This is a server chat enhancing mod that adds support for LuckPerm's prefix/suffix to display in chat. It also adds support for coloring users and their group roles based on metadata inside LuckPerms
The format is completely customizable in the config, and supports some additional display items like displaying the server timestamp in a player's message.
It also modifies the tab list to display things like the player's Vault Difficulty and Vault Level inside the tablist.
