Overview

Applied Energistics: Crystal Science (AECS) is an addon for Applied Energistics 2 that brings back the Purified Crystal concept and builds a full progression around it.

With a production chain of Dust → Seeds → Growth and dedicated machines (Grindstone / Pulverizer / Growth Chamber / Aggregator), you can mass-produce purified crystals for mid-to-late game crafting and energy generation.
On the other side, AECS adds stronger pattern execution and wireless channel solutions (Meteorite/Resonating Pattern Providers, Ender Emitter & Ender Broadcaster) to build more powerful automation.

All items and blocks added by AECS including crystals, machines, tools, and ME devices
