Wild Magic

Wild Magic (ワイルド・マジック, Wairudo Majikku) is the primal magic that existed in the New World long before the introduction of Rank Magic.

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, who introduced to the inhabitants of the New World the power of the more effective Rank Magic. Since then Wild Magic has been in decline, though a few practitioners of the art still exists.

Mechanics
Wild magic is different from typical magic, instead of mana it seems that it requires the caster to spend and use of souls in order for a spell to be cast. The spell casting through Wild Magic is said to be astronomical, requiring the sacrifice of people and destroying the link in user’s soul to cast a strong magic.

Dragon Lords can cast Wild Magic with ease but it seems that due to the intrusions from YGGDRASIL, Wild Magic has been becoming more and more difficult to cast. One way to access Wild Magic is to possess the blood of a Dragon Lord. But even if a person does possess a trace of a Dragon Lord’s lineage, for a person far weaker than the former the sacrifice for casting would be huge, estimating to be around millions.

Trivia

 * Wild Magic can also be used to forge magical items, an example would be Gazef's ring.
 * In the web novel when Ainz tried to absorb the fallen soldiers exp, he ended up absorbing their souls. So we can say that the wild magic consumes EXP rather than MP.
