Mystical Agriculture: Growing Resources with Crops
Mystical Agriculture lets you grow almost any resource as a crop, from ores to mob drops. This guide covers the essence system that makes it work.
Essence and Prosperity
The foundation is 
Inferium Essence, the base magical material, and Prosperity Shards. Combining essence with a Prosperity Seed Base and the target resource creates a seed for that resource — plant it, and it grows a crop that yields essence of that material.
Essence tiers
Essence climbs a tier ladder, and higher-tier crops need higher essence to craft: Inferium, Prudentium, Tertium, Imperium and finally Supremium. You upgrade essence up the ladder, and better seeds require the stronger tiers, so progression is about climbing this chain.
Getting started
Start by farming Inferium, craft your first resource seeds (common ores and materials), and use the essence to climb toward the higher tiers. With over 130 resource crops available, Mystical Agriculture can eventually grow nearly any ingredient, ore, or mob drop you need — the farming and gear guides cover speeding up farms and the mod's tools and armor.
