Hello and welcome to the page dedicated to the maintained plugin "PvmArena", i used to have a plugin on this page called starter but a plugin called essentials had all the features and more which that had.
What is the plugin and what does it do?
This plugin does one main thing, it allows you to create a arena where players may fight monsters to try earn rewards, you can customise which monsters spawn and you can set who can go in the arena and who can use certain classes.
Why pick this over mobarena?
I think you should pick this over mobarena because this plugin comes with much more flexibility in what type of waves you want to spawn and it comes with lots of cool features, this also has OP override, like starting the arena with commands, this prevents misclicks whereas on other plugins when you press the block you are ready no matter what!
Another reason why i think you should pick this over other mobspawn plugins is that this plugin is heavily tested and uses the code which prevents this plugin from crashing your server! as well as these features you also have a spectator mode where players can roam around in the arena loaded with mobs and watch other players! this is configurable (incase you dont want players telling others what is outside the door!)
This plugin comes with full compatibility with permissions so no matter which permissions plugin you use this SHOULD work.
