Custom Seeds
by Hyperreal
Custom Seeds adds twelve crop seeds that are crafted from raw materials such as Raw Iron, Diamonds and logs, on Fabric for 1.21.4.
What it does
Crafting happens at a crafting table: place one vanilla Wheat Seed in the right center slot and surround it completely with one of eight base materials. Eight Raw Iron with one Wheat Seed yields an Iron Seed, and eight Diamonds with one Wheat Seed yields a Diamond Seed. Note Wood and combinations of vanilla logs produce a Log Seed, which accepts any mix of logs. Each custom seed is planted on farmland, grows with bone meal, and is harvested by right-click.
Harvesting a fully grown custom crop rolls seven random items from a dedicated loot pool, which can include a Diamond Sword, an Enchanting Table, diamond armor, crafting tables, shields and wooden gear. Crops never drop their own seed, and dying clears the inventory with a high stakes death penalty. Pistons destroy custom crops instead of moving them, and flowing water washes them away, so they need protection. The mod runs on client and server, and Fabric Loader 0.18.5 or newer with Fabric API is required on Minecraft 1.21.4.

Key features
Twelve craftable seeds
The mod adds twelve seeds, each made from a base material combined with a standard Wheat Seed at a crafting table.
Lucky 7 loot harvest
Harvesting a grown crop triggers a loot roll of seven random items from a specific loot pool instead of a plain crop drop.
Crop protection rules
Custom seeds never drop themselves, and crafting and growing keep working as before, which limits seed duplication.
Death penalty
Dying clears the inventory, a high stakes rule that changes how far players range from base.
