Antars adds many things, but the main idea of the mod is a leveling system based on ranks, that goes from rankF, all the way to rankA. It adds Bosses, items, tools, and many more.
To level up In the ranks you need to craft a aplication item, and use it to spawn the tester of the specific rank, when you kill the tester, he will drop a rank(f,e,d,c,b,a) item.
there is also bosses that makes the mod more challenging
gecko lib is required for this mod.
