Hi basically BSkyblock has 0 addons and no way of adding important addons such as Island Levels and challenges. These all Support 1.14 and work with the latest version of BSkyblock. All you have to do is drop the .jar file into the addons folder inside BentoBox but as we can not upload .jar files we cant make BSkyblock a feature heavy plugin like its competitors uSkyblock and EpicSkyblock which both have their flaws :
You can find these adddons here at https://github.com/BentoBoxWorld/BentoBox
It is fine if all cannot be added however the essential ones with their respective reasons are:
Level: One of the main points of Skyblock is to level up your island and win a Paypal reward which most servers are now doing.
Challenges: Players need challenges as it gives them something to do
MagicCobblestoneGenerator: Every player makes a cobblestone generator when creating an island, It spices it up
IslandFly: Some servers dont wish to allow players to have permanent fly so being able to fly just on your island is quite nice!
Greenhouse: Does look pretty cool I cant lie. No other reason that should be added lol
Thanks for reading and considering, This is my first suggestion so excuse me if I have done something wrong like put it in the wrong place or not included enough information. Hopefully this can be added quite soon. Have a nice night
