So I've been playing Tekkit Legends for a bit now and wanted to make some Power Armor. I made the armor and the tinker table, but realized it's seems a lot of modules are missing. Crafting recipes won't show for some modules and there is no way to power the suits. I have tried an MFE and a universal charger. I'm wondering if some of the functionality of this mod was removed? Or if not, how is it supposed to be used? What have you guys been able to accomplish with Modular Power Suits?
