Equivalent Exchange 3, or EE3, adds the magical concept to Tekkit Lite. The mod has been completely redone and is, for the moment, lacking many of the features in EE2. It is currently in pre-release 1.
It is important to note that EE3 has currently removed Condensers, Energy Collectors and Antimatter Relays, however the mod creator has stated that the finished mod will include something akin to them.
Red Matter is also removed, but Dark Matter will be retained.
