The elves have long delved into the magic and arcane as evident by their cultural centerpiece, the Sunwell. Thus, they have developed a natural Arcane Affinity as a result of the well’s magical presence, making the blood elves naturally skilled with arcane arts such as Enchanting. The elves’ constant exposure to the Sunwell also gave them a natural defense against many kinds of magical manipulation, granting them a natural Magical Resistance. After the destruction of the Sunwell during the Third War, the remaining blood elves developed the skill of Mana Tapping to feed their magical addiction, allowing them to tap into the arcane energies of other beings. Arcane Torrent comes as a natural manipulation of these consumed energies and allows the elves to absorb and unleash the energies gathered.
