It does refer to rituals, sacrifice, Gaia, demons, and elementals, which some find offensive, but if you mean foul language then I've never seen any. It's a rather polished mod that is seen commonly in modpacks nowadays, to the point of having crossovers with other mods.
As for balance, my only concern might be the ritual of magnetism. Basically a very slow ritual that works like the ore magnet in twilight forest. That said, it doesn't hold a candle to the ridiculous atomic disassembler.
Overall though I approve. As I said it really is my favorite mod ever, and takes a loooong time to advance through the tiers.
