Wild Magic

Wild Magic (ワイルド・マジック, Wairudo Majikku) is the ancient, or primal magic that has existed in the New World long before the introduction of Tier Magic. It may even perhaps be known as the magic of the soul. Fluder stated that this type of magic tends to go by many different names. They're considered to be one of the powers alongside Martial Arts, Talents, and Runecraft that did not exist in YGGDRASIL.

Background
Six hundred years ago, Wild Magic was the dominant magical art in the New World. The true masters of Wild Magic were the Dragon Lords. However, Wild Magic fell into disuse when the players from YGGDRASIL introduced the more effective and efficient power of Tier Magic. Since then, use of Wild Magic has fallen, though a few practitioners of the art still remain. And because of the genocidal slaughter of most of the Dragon Lords by the Eight Greed Kings 500 years prior, there are very few left who can use Wild Magic, like Draudillon Oriculus.

Mechanics
Wild Magic differs from typical magic in that instead of mana, it requires the caster to use souls in the casting of their spell. Although the cost of spell casting via Wild Magic is grisly, the results speak for themselves; the more people sacrificed, the stronger the magic when released. Using Wild Magic can also destroy the user's link to their own soul as well, making the casting of stronger magic a gamble.

Dragon Lords can cast Wild Magic with ease, but it seems that the intrusion of YGGDRASIL Players has somehow caused even their ability to use it difficult. One way to access Wild Magic is to either possess the blood of a Dragon Lord or be born with a Talent that can let potential individuals used it. But even if a person does possess such heritage, the weaker the descendant, the greater the sacrifice of lives shall be to perform the magic, with estimates upwards of millions of souls.
