But really, what else are you going to use the EMC for? In my last world I had a machine that created and dumped Red Matter Furnaces into lava just for the hell of it.
Gem armour lets you fly, shoot lighting, send mobs flying away from you, cause a massive explosion in the area around you, breathe underwater, makes you lavaproof and looks badass. If that's not god tier, I don't know what is.
That requires 3 warning points, the maximum warning I'd give for not searching is two. Also, that's very close to backseat modding, which is also against the rules.
Yeah, I suggest just going ahead with Tekkit. She's as well learning everything from scratch than learning how Vanilla works, then relearning everything when you move to Tekkit and it's new startup.
