This expansion adds 30 new wands and 10 new magic classes to the game. Each player can have no more than two magic classes at once, and there is a leveling system in place to unlock new magic.
When using this addon, PvP is enabled by default. If you want to play with your friends in a survival world without PvP, use the command /function disablemagicpvp, and most magic will not harm other players.
