If you don't have any money, you can vote for the server and you will be rewarded $20, unless you get a lucky vote. Good luck on your quest for diamonds!
Skyblock tips for diamonds: 1.Vote to get money, then go to peoples shop to buy the diamonds. 2. Set up a shop, I can set a warp for you and advertise for you shop, /warp how_to to see how to set up a shop, then put in (I would suggest farming materials for non-donors) get money that way, then buy diamonds at peoples shops. 3. Buy a rank... VIP: 1 diamond per day, MVP: 2 diamonds per day, Executive: 3 diamonds per day, CEO: 4 diamonds per day, Admin: 5 diamonds per day, Timeless: 15 diamonds per day. Buy ranks (once your in Skyblock) at /warp donate. Also the kits come with more items than just diamonds. Also see the list of what you get in your kit at /warp donate. Hope this helped. Thanks. -Smaug
