About FTB StoneBlock 4

The Stone Remembers You wake surrounded by stone. No sky, no horizon, just you, surrounded by what seems to be endless stone. But this time, the stone speaks back. StoneBlock 4 is the next chapter in one of modded Minecraft's most iconic series, rebuilt from the ground up to deliver the underground survival experience you know and love, now with deeper progression, narrative-driven gameplay, and of-course, randomized rewards! The Vaults: Ancient Trials Deep within the stone lie the Vaults, ancient trial chambers filled with light, shadow, magical mysteries, and technological marvels. Each Vault tests a different skill: logic puzzles, brutal combat encounters, and endurance challenges that shall push you to your limits. Vaults are handcrafted experiences that reward exploration with rare loot, unique resources, and progression materials you can't find anywhere else. Conquer the Vaults, and you'll unlock the secrets needed to truly master this modpack. Echoes of the Old World Hidden below the Garden of Stone are the Echoes, they're holographic remnants of the civilizations that came before. Each Echo inhabits a handcrafted sanctuary and serves as a living guide on your journey. From the Echo of Guidance to the Machinist and Quartermaster, these Echo's will unlock new quests, tell stories of the stone filled world, and offer meaningful trade. The World Engine: Your Journey's Heart At the centre of it all stands the World Engine, a massive ancient relic that powers your progression. Introduced early and revisited throughout your campaign, the Engine grows with you—unlocking new crafting tiers, revealing lost technologies, and ultimately reshaping the world itself. With over 15 unique multiblock upgrades, the World Engine transforms from a mysterious artifact into the beating heart of your operation. Every upgrade brings new recipes, new possibilities! The Garden of Stone: Choose Your Path Every journey begins in the Garden of Stone, a vast underground glade lit by amethyst light. From here, you'll choose one of five unique starting islands, from the classic stone box survival to thriving biomes alive with mystery. As you progress through six Foundation Chapters, each with branching questlines, you'll unlock new chambers and awaken dormant Echoes. Complete two paths to advance, or finish all three to uncover deeper lore and premium rewards. The Unearther: Villager Powered Automation?! Resource gathering in SB4 has been reimagined. Early on, you'll use a simple brush to sift raw ore chunks from gravel sand and dust, slow at first, until you realise you can ultisift! Then you'll discover the Unearther: a glass cube housing a villager who tirelessly refines the debris you give, as long as you feed them! The more care you provide through food, tools, and upgrades, the more efficient and skilled your villager becomes. There's also new villager professions like the Archaeologist, Geologist, and Dimensionalist. Solo or Together Wheth
