I'm playing in a single player Skyblock world, the OG type without the nether and i want to get gravel so that i can duplicate my dirt. does anyone know how i can do this? everyone on the internet says in the nether but i'm playing in the version without the nether
Don't think there is a way to get gravel without the nether. The actual method is to get piglins to barter for gravel, but this cannot be done in the overworld.
not sure exactly what dupe you are using, but perhaps sand could work as well? Since both sand and gravel have similar block properties. If so, you can always wait for a wandering trader to spawn, and then trade with it for sand. Emeralds you can get from either a villager farm, or get really lucky when killing foxes (fox farm).
He is trying to get 2 dirt + 2 gravel = 4 coarse dirt, which can be tilled to get dirt. This is disabled in sb to avoid duping dirt which is why you don't know it
The alternate solution to more dirt is to get moss and spruce saplings from a wandering trader. Grow the spruce tree on the moss, converting it to podzol, then till the podzol into dirt.
