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 Paradyne 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 look upon as the dominant magical art in the New World prior to Tier Magic. The masters of Wild Magic in particular were the true Dragon Lords. According to Draudillon Oriculus's grandfather, with the power of Wild Magic, one could create an explosion that could closely rival the Platinum Dragon Lord’s ultimate attack.

However, Wild Magic fell into disuse when the players from YGGDRASIL introduced the more effective and efficient power known as Tier Magic. Since then, use of Wild Magic has fallen quite drastically, though a very few practitioners of the art still remain. This includes the surviving Dragon Lords who did not participate in the war against the Eight Greed Kings.

And because of the genocidal slaughter of most of the Dragon Lords by the Eight Greed Kings five hundred years prior, there are now a few left who can use Wild Magic, like Draudillon Oriculus to this day. At some point in time, it seems apparent that extremely rare users of Wild Magic are still being sought out by the likes of Fluder Paradyne and the Slane Theocracy.

Mechanics
Wild Magic differs from Tier Magic as instead of mana, it requires the caster to release souls in the casting of a powerful spell. Although the cost of spell casting via Wild Magic is grisly, the results speak for themselves; the more people are offered up as sacrifices, 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 risky gamble in and of itself.

Fortunately, pure-blooded Dragon Lords can cast Wild Magic with ease than those who're hybrids with partial dragon blood. However, due to the intrusion of YGGDRASIL Players and their magic, it has somehow caused even their ability to use Wild Magic difficult. According to Platinum Dragon Lord's words, now, with the powers of Wild Magic tainted and twisted, it would be very difficult to create something like Climb's ring ever again.

In order to gain access to Wild Magic, one must 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 Wild Magic, with estimates upwards of millions of souls. As a result, even a descendant such as Draudillon Oriculus had difficulty utilizing it properly.
