Version: 7.3.13
I'll admit, I was a little confused when I first found this plugin as to what exactly it was, although intrigued - so I went ahead and gave it a shot.
Boy, let me tell you, I have not been disappointed in the slightest. My players love this plugin. Some of my users were skeptical, but with a few days of testing, configuration, and customizing some of the configurable options, I have fallen in love with this plugin and so have my playrs. I've hardly had a chance to dive into it myself, but I'm aware of how it works, what it offers, and how it can benefit those looking to enhance their Minecraft experience.
Pros:
A full-fledged, plug & play dungeon, lair, and added-mobs system. This can fit right into most survival servers, likely without issue. You will need to configure things a tiny bit to your liking, such as removing certain powers, certain mobs from having elite variants, etc. although it is incredibly easy to do, and worth it.
100% Plug & Play dungeons, lairs, bosses, etc. - When loading in a pre-made dungeon or a lair (all of the ones advertised here), the WorldGuard region is already made for you around the structure or in the dungeon world - you don't really have to do anything, except reload the plugin to ensure portals spawn where they are supposed to.
An overall enhanced PVE experience, with pursuing dungeons, lairs, etc. being optional - those who do not wish to interact with them do not have to, besides the occasional elite mob battle that spawns around them, which usually are not too difficult, as this plugin scales the elites' difficulties to each player's level.
A perfect addition to any server that doesn't want to stray too far from a vanilla experience - but wants the option to do more in their server, battle more difficult mobs, or fully dive into the custom worlds, lairs, adventures, etc.
Near-constant, and immediate support from the developer himself in his Discord server. He knows what he is doing, gives fast, simple responses, and will help you with any issues, questions, etc. that you have. He treats patrons, non-patrons, etc. all the same, and helps everyone who needs help with the plugin.
Cons:
Though totally fair, hardly a con, and VERY WORTH paying for, some of the add-ons are premium and cost a small fee. You can get all of them via the authors patreon, or by buying them on the itch.io page for around 5 bucks.
^ This isn't particularly a con, but for those budgeting, it can be a downside
However: about 50% of dungeons & lairs are completely FREE for download - so not having the funds for the premium ones won't hinder your experience whatsoever!
Overall 10/10 plugin, developer is amazing and continuously works at the plugin, community, etc.
Absolutely wonderful!
