How to Make Seeds with the Infusion Altar
Build the Altar
Place an Infusion Altar and surround it with Infusion Pedestals (place pedestals in a ring around the altar). Put your base seed item on the altar and the required essence on the pedestals.
Infusion Recipe Logic
Infusion recipes (mysticalagriculture:infusion) combine a base seed with essences to produce a tier seed. For example, tier-one seeds use Inferium Essence plus a vanilla seed or crop item. Higher tiers require the previous tier's Essence and additional materials. Check each seed's recipe in JEI/REI — the number of pedestals used varies by recipe.
Getting More Seeds
Once you have one seed of a type, plant it on Inferium Farmland (or higher tier farmland). Harvest the crop to get Essence and sometimes extra seeds. Use the Seed Reprocessor to convert surplus essence back into seeds: feed it essence and it outputs seeds via the mysticalagriculture:reprocessor recipe. This is the main loop for scaling seed production without re-crafting each seed by hand.
Tier Progression
Start with Inferium Essence seeds, then craft Prudentium, Imperium, Supremium, and finally Awakened Supremium tier seeds. Each tier's essence is made by combining the previous tier's essence in a crafting grid (shaped/shapeless recipes), then used in infusion to upgrade seeds.
