This is my first modpack. I had fun while playing skyblock with these mods, so I decided to share it with the world.
This is a very light modpack, so it's not gonna be fabulous like SkyFactory or others.
Spoilers below show helpful tips in case you don't want to figure stuff out:
You'll start with unlimited glass, but no other way to get items. You'll have to use the water to make a glass platform as low as possible in order to gather all of the falling stars. With them, you can make blocks that you can use for a mob farm. You can also get dirt blocks by throwing yourself into the void. Dying in the void will cause a dirt block to spawn at y=1. From creepers, you can get leaves. In the End, you can get obsidian that you can turn into lava. Enjoy!
P.S. There's an End Portal Frame below the spawn.
There is a book in the starting chest that gives you quests. These are just in case you run out of ideas.
