OctoComputing

Breaking leaf blocks can drop a mystery leaf with a 0.1% chance, and that leaf grows a mystery sapling into a tree of its own wood type. Placing the nine vanilla leaf item types into a crafting table in one grid produces a mixed leaf that acts like ordinary leaves and appears in several other recipes. Compressed leaves and double compressed leaves serve as furnace fuel, burning for 10 and 100 ticks. A leaf ore in stone and deepslate yields leafstone when mined.

Leaf monsters spawn at night and stay neutral unless attacked, and about 1% of them drop a leafite upgrade template. That template upgrades netherite into leafite. The leaf god is a boss modeled on the wither: it is summoned with a craftable token, is stronger than the wither, and drops a broken leaf when defeated. A broken leaf is repaired with leafstone blocks and double compressed mixed leaves, and the repaired leaf core is combined with the upgrade template to make leafite netherite.
