BackStick: BackMutator Transmutations and the Dragon Egg Chain

The BackMutator is BackStick's alchemy-free transmutation tool, converting surplus mob drops, bleaching dyed blocks, and mutating ordinary skulls all the way up to a Dragon Head and Dragon Egg.

Crafting All Seven BackMutators

Each BackMutator pairs four matching BackSticks with a single unit of that tier's base material — making it two ingots or gems lighter than a BackEngraver:

• Wooden BackStick x4 + any planks -> Wooden BackMutator
• Stone BackStick x4 + stone tool materials -> Stone BackMutator
• Copper BackStick x4 + Copper Ingot -> Copper BackMutator
• Iron BackStick x4 + Iron Ingot -> Iron BackMutator
• Golden BackStick x4 + Gold Ingot -> Golden BackMutator
• Diamond BackStick x4 + Diamond -> Diamond BackMutator
• Netherite BackStick x4 + Netherite Ingot -> Netherite BackMutator
• Diamond BackMutator + Netherite Ingot -> Netherite BackMutator (at a Smithing Table)

Just like the mod's other netherite tools, upgrading your Diamond BackMutator at a Smithing Table costs one Netherite Ingot instead of the three ingots required to craft four Netherite BackSticks plus a loose ingot on a bench.

Everyday Drops, Bleaching, and Rare Rebuilds

Combining any BackMutator with common blocks and drops clears out junk chests and synthesizes hard-to-farm vanilla ingredients:

• Bleaching & crops: strips dye from colored wool, beds, or terracotta back into White Wool, a White Bed, or plain Terracotta, and swaps a Pumpkin into a Melon (or a Melon back into a Pumpkin)
• Bulk curing & sifting: turns Rotten Flesh into Leather (one in a shapeless craft, or six at once in a shaped grid) and sifts Gravel into Flint (one shapeless, six shaped)
• Soil & mob drops: mixes dirt, sand, and Gravel into Clay x3; Bone Meal + Egg + Green Dye -> Slimeball; Feather + Gunpowder + Iron Nugget -> Ghast Tear; and Amethyst Shard + Diamond + Emerald + Glass Bottle -> Bottle o' Enchanting x2

Mutating Skulls into a Dragon Egg

BackMutators also drive a complete trophy-head ladder. Pairing any BackMutator with an existing mob head and a signature drop reshapes that head into another species:

• any head + Bone -> Skeleton Skull
• any head + Rotten Flesh -> Zombie Head
• any head + Gunpowder -> Creeper Head
• any head + Wither Rose -> Wither Skeleton Skull
• Creeper Head + Skeleton Skull + Zombie Head + Wither Skeleton Skull -> Dragon Head
• Dragon Head -> Dragon Egg

Notice how the BackEngraver and BackMutator lines interlock here: you can carve your starter Skeleton Skull out of a plain Bone Block using a BackEngraver, mutate three copies with Rotten Flesh, Gunpowder, and a Wither Rose to collect all four Overworld and Nether heads, fuse those four into a Dragon Head, and mutate it once more for a renewable Dragon Egg.
