Elementals are a bit of a special type of monsters, they appeared on Earth a few decades ago, after the mana density of the planet increased to a suitable level. Elementals, are monsters with only a single affinity, and are also closely related to spirits.
Almost all of them have incorporeal forms, immune to pure physical attacks. Of course, coating your weapon with any type of energy will still deal a good blow. Elementals, individually, are quite strong, however, are quite stupid.
Elementals lack intelligence, since they are quite literally mana taking the form of a monster. They only begin to possess intelligence after S-rank and beyond, and even then, in limited forms. Elementals, beside the lack of intelligence, also have one profound weakness.
