Originally, this was a Botania with it's Garden of Glass addon (which changes the default recipes of Botania to make them skyblock friendly), and a few extra mods to make it playable without having to worry about hostile mobs (if you prefer it that way). To get hostile drops, you can either craft them or use emeralds to buy them in the Farming for Blockheads Market until you can get or craft a rotten egg from Mob Grinding Utilities which when placed on dirt, will make a 5x5 of hostile dirt (spawns mobs if light above it is > 10). If you wish to go mining, I've included a mining dimension that doesn't have caves. JEI and it's addons can also tell you how to get resources by trading with villagers (you can breed them after buying villager eggs from the Market).
Now it's a small skyblock pack that is focused around Botania as the main mod (though you can use other mods if you prefer not to).
To find out which mods are in this modpack, check out the Relations tab, and pick Includes as the filter type.
Consider supporting me on Buy Me a Coffee so that I can continue making more modpacks!
