Mining Plus Enchantment

When the enchantment is on a tool, breaking one block also breaks the blocks beside it on the plane the player faces: eight in total, laid flat when the player looks up or down, and upright against a wall. Sneaking turns the effect off so a single block breaks normally. Every block in the area follows the same drop logic as vanilla, so each one yields its own loot, and Fortune and Silk Touch apply as they normally would. Tool tiers are enforced, so a stone pickaxe still cannot harvest diamond.

Each extra block costs one point of durability, which makes a 3x3 break cost the same as nine separate hand-mined blocks. Unbreaking keeps its normal behavior. Hoes till a 3x3 patch on right-click and shovels path one. Blocks such as bedrock and portals stay untouched, as do container chests and shulker boxes. Hanging roots still drop from rooted dirt. The enchantment is a separate treasure type that never appears on the enchanting table; it can be found in enchanted books and from librarians, who sell books at double the usual price. Ore XP scales with the broken blocks, and anvil cost is 8.
