This server uses a password plugin to combat cracked players logging into other player's accounts. The plugin, known as LoginSecurity on SpigotMC, is a simple and straightforward, but very effective plugin to help and protect all users. Once you first join the server, the plugin will ask you to register, via this syntax: /register <password>. once you have registered, you can play as normal. When you log off for a long period of time, and log back on, you will be presented with darkness and the plugin asking for your password, via this syntax: /login <password>. Once you have logged on, normal gameplay will resume, however, if you don't sign in, you will not be able to move at all. If you forgot your password, open a ticket in support. Once you're logged in, you can also change your password, via this syntax: /changepass <old> <new>, and you can logout, via /logout.
PowerGems is a plugin that adds magical gems to the server. There are ten unique gems in the plugin that spice up the PvP experience in the game, however, you can only get one and the plugin assigns it to you. Far more information about the ten gems and their abilities can be found at https://powergems.iseal.dev/overview/the-gems-and-their-ablities and https://modrinth.com/plugin/powergems.
