In mid air, Rowling stands on the dark green barrier and nervously looks at the legendary mage Phil in front of her.

Unlike Rowling, who doesn't have the ability to fly, all the movements in the air need the help of Hercules shield to achieve this. Phil can move freely in the air with only one flying magic.

After the battlefield is completely pulled to the sky, the huge number of corpse witches in sao'ou cannot pose any threat to Phil in the air. The cloud of death emitted by the corpse witches will dissipate before it reaches Phil. Only a few of the corpse witches can reach this position, but it will be dispersed by Phil's magic.

On the contrary, Phil's large-scale magic can easily cover most of the city of Sao and bring a devastating blow to the corpse witches.

Under the influence of the magic cast by the legendary mage, both the original buildings in the city and the corpses and witches in it will be easily destroyed. There are few other ways to limit the legendary mage's ability except to confront him.

For this reason, even if it costs a lot of mana, Rowling has to rely on instant movement and Hercules shield to make herself come to the sky, trying to use magic to limit the legendary mage in front of her.

Rowling's Death Knight Hero, Thunderbird, has long been sent by her to block the arrival of the rear mage troops, unable to bring any help in her duel with Phil.

In the face of the real legendary mage, Rowling deeply felt her own weakness. No matter how much she mastered the types of magic, or how much she used magic, especially for the change of the inherent form of magic, Rowling was far behind the real legendary mage.

Seeing that Rowling came to the sky, Phil didn't rush to fight the necromancer in front of him. Instead, he forced Rowling to consume mana in accordance with the common fighting method among high-level mages.

The way of forcing is also simple. Rowling will not allow Phil to cast a large range of magic on the lower Sao city. As long as Phil shows such a move, Rowling will have to attack the legendary mage in front of her, thus consuming more mana.

Phil's fighting ability is extraordinary. Any spell cast by Rowling can be easily resolved by him. Even if Rowling casts a high-level spell, Phil can also use an instant move to get away from the shadow of the spell. Rowling has to spend more mana to keep up with Phil's position.

Maybe he felt that there was more power left, or maybe he wanted to force Rowling to cast the magic again. In the interval between the fight with Rowling, Phil found the right time to cast a number of large-scale damage magic towards Sao city below.

Even if you take into account the magic cast on Sao O city, Phil's mana consumption is still far less than Rowling's, plus Phil's own casting ability, which is undoubtedly a great advantage.

Even though Phil, a legendary mage, is much better than Rowling in terms of rank, he still chooses the safest way to fight when he realizes Rowling's heroism. He uses his advantage in casting ability to consume his opponent's mana until his opponent's mana is consumed to a certain extent, Will really take the hand and end the battle.

One after another, she cast her magic, but it was difficult to achieve any effect. She felt the sharp drop of mana in her body. For a moment, Rowling could not help feeling impatient.

In the process of fighting, some skills of saving mana, which are only mastered by real legendary mages, also begin to be reflected in Rowling's casting process.

For example, in pursuit of Phil, the Hercules shield appeared at Rowling's feet after the instant movement to shorten the distance. The area occupied by the Hercules shield was significantly reduced. It was no longer an elliptical plane, but separated from it. Finally, it only formed two smaller planes under Rowling's feet.

In addition, when Rowling casts Hellfire against Phil in mid air, she will limit the explosion range of this spell to the extent that it can cover a large area, reducing the mana cost by several times.

Rowling saved a lot of Mana by adjusting the effect of a given spell, especially on a large range of spells.

Rowling has long had the ability to make changes to shaping spells. According to the information rod told her, this should be a unique ability based on the hero's expertise. For orthodox mages, only when they become legendary mages can they have access to this ability.

Before that, Rowling had tested her ability, and rod also gave some guidance, including how to use the powerful aegis.

In Rowling's impression, according to rod's words at that time, using this special ability, the mage can consume a very small amount of mana and use the Hercules shield to walk freely in the air without mastering the Flying Magic.

At that time, although Rowling understood this point, and also made an attempt through her own strength, she failed to achieve much. Rowling could not achieve the effect mentioned by rod.

Every time she uses her powerful aegis, Rowling can't effectively reduce the scope of this dark green barrier. At most, she only reduces it by one circle. However, the battle is often full of variables, and there is no comfortable casting space. It is impossible to apply this ability to actual combat.

In addition to this way of use, in the hands of some legendary mages, powerful aegis is sometimes used as a personal skill.

To achieve this effect, we need to fold the powerful aegis, and finally limit the creature to it. Although releasing multiple Hercules shields at the same time can achieve a similar effect, compared with the cost of mana, it is undoubtedly not worth the loss.

In the face of creatures who are not good at magic, this kind of immobility effect can be brought into full play. After countless folds, the legendary mage's Hercules shield can completely fit the biological body, making it unable to exert any power.

However, in the eyes of the mage, the cage made up of powerful aegis is just a thing that can be escaped by moving in an instant.

At this time, in the contest with the real legendary mage, after deeply feeling the opponent's casting method, Rowling realized that every point of mana value is extremely important, and the ability to adjust the given spell can directly affect the outcome of the battle.

Compared with the previous practices, Rowling's ability to control magic has improved rapidly in actual combat, especially when her opponent is a real legendary mage. Except for the panel attribute, the magic she casts is almost the same as the real legendary mage in form.
