what is setlevel fr?

This is a plugin for Grasscutter, a game server framework, that lets you quickly change character levels without restarting or logging out. Instead of grinding through the game normally, you can instantly set any character to any level you want through simple text commands. The plugin works by intercepting commands you type in-game. You type /level 50 to bump your current character to level 50, /level team 50 to level up everyone on your active team at once, or /level all 50 to max out your entire roster. The changes take effect immediately, you don't need to relog or restart anything. This is especially useful if you're testing, managing a private server, or just want to skip the grind. Game server admins and private Grasscutter server owners would use this most. If you're running a custom server for friends, you might want to let players jump straight to endgame content without spending weeks leveling. Or if you're developing or debugging Grasscutter itself, you need a fast way to set up test characters at specific power levels. Installation is straightforward: grab the latest .jar file from the releases page and drop it into your Grasscutter plugins folder, then restart the server. The plugin is straightforward by design, it does one thing and does it well. The author notes it was built for Grasscutter versions 1.3.1 and 1.4.4 but should be compatible with most versions in between. The README includes a small warning to use the commands as intended, suggesting there may be edge cases if you misuse them, but nothing too complicated to worry about.
