Sons of Sins Mod Guide: Progression from Flesh to Soul Steel

Early Tier: Flesh and Organs

Start by collecting flesh and organ drops and turning them into Buckets of Blood. Craft the base blocks: Block of Flesh, Block of Hearts, Block of Muscles, and Block of Ribs. These are your foundation. From them you build the first tools: Osseous Axe, Osseous Hoe, Osseous Pickaxe, Osseous Shovel, and Osseous Sword. Also craft the Urn and the Flesh of Demise, which are used in later recipes.

Mid Tier: Mob-Specific Materials

The §6 tier introduces mob-specific blocks and items: §6Blazing Heart, §6Creeper Ribs, §6Enderman Muscle, §6Ice Heart, §6Ravager Muscle, §6Slime Rear, §6Spider Heart, §6Strider Muscle, §6Golem Cuirass, and §6Flesh Carcass. These come from specific mobs and are combined into their block forms (§6Block of Blazing Hearts, §6Block of Creeper Ribs, §6Block of Cuirass, §6Block of Enderman Muscles, §6Block of Ice Hearts, §6Block of Ravager Muscles, §6Block of Slime Rear, §6Block of Spider Hearts, §6Block of Strider Muscles).

Late Tier: Sinful and Ether Gear

Upgrade Osseous tools into §7Sinful Axe, §7Sinful Hoe, §7Sinful Pickaxe, §7Sinful Shovel, and §7Sinful Sword. Then push into the §e tier: §eEther Lantern, §eEther Sword, §eIron and Ether, §eSoul Steel, §eSoul Steel Block, §eSoul Steel Chain, §eSoul Steel Door, §eSoul Steel Slab, §eSoul Steel Stairs, §eSoul Steel Tiles, §eSoul Steel Trapdoor, §eRemnant Boots, §eRemnant Chestplate, §eRemnant Helmet, §eRemnant Leggings, §eShape-Shifting Tool, and §eSickle Of Struggle. Soul Steel is the backbone of the endgame — build its block, chain, door, slab, stairs, tiles, and trapdoor variants for base construction.
