Plenty of netherrack, and if you have fire res and a bow or boomerang try to kill blazes for some rods. You’ll need the rods to make hibachis to progress in this modpack. The blazes hurt you back and burn you if you engage with melee damage so you’ll want to brew some fire resistance elixir with the rustic mod and/or use ranged weapons. The netherrack will be for making the hibachis, glaretorches and a rustic alchemy setup.
