The proposal is good where you can have a variety of dragons for your server, but the plugin is unfortunately incomplete and with a big TPS loss when it generates a dragon at the end, not being able to edit the file to make your own dragons and do the translations of the speeches, there is also a lack of commands for the server both to manage the mobs and to reload the plugin.
A great plugin! Finally I can give the Enderdragon the place it deserves on my server and finally become a real boss and not a mob that you farm and that just brings more money than the others! A lot of settings to customize! A huge thank you.
