This plugin requires ProtocolLib 4.4.0+ , and OPTIONAL PlaceHolderAPI 2.10.7+
Notice: If you are trying to replace colors in your ReplacerConfig, use '§'(Vanilla Minecraft color character) instead of '&'(Bukkit color character). e.g. §3§l instead of &3&l

┃ Introduction
ProtocolStringReplacer is a plugin that realizes the function of replacing strings by editing packets. It is committed to optimizing efficiency and providing more functions for use.
Because only the packet sent to the player is edited, plugin will not affect the processing from the server.
