Doomed with cobble

Story: You wake up one morning to find yourself on a decently big stone platform and realising that you were not sleeping on a bed but on a soft rock that forms into stone.

This skyblock modpack doesn't let you start ontop of a tree but on a stone platform with the questline giving you cobblestone.

This modpack just shows what you can do with just one cobblestone with the ability of being able to douplicate it.

The three main mods that you need to use for beating the game(or is the mod that contains the final item) are Projecte, Mystical agriculture and Storage drawers.

You will be able to go through tinker's construct for it's  ________  block and will get you one of the most important items in the modpack

go through storage drawers for its _____ upgrade

but most importantly is to get the final ________

I don't what else to say without any spoilers so I hope you have great fun playing :)
