In mid-air, Rowling stood on a dark green barrier, nervously looking at the legendary mage Phil in front of her.

Unlike Rowling, who is not capable of flying, all movements in the air require the help of the Hercules Aegis to achieve this, and Phil only needs to cast a flying thaumaturgy to move freely in the air.

After the battlefield was completely pulled into the sky, the original large number of corpse witches in Ao City could not pose any threat to Phil in the air, and the death cloud shot by the corpse witch dissipated on its own before it rose to Phil's side, and only a few corpse witch kings' attacks could reach this position, but they would then be dispersed by the spells cast by Phil.

On the contrary, the large-scale spell cast by Phil easily enveloped most of Ao City, bringing a devastating blow to the corpse witch who had just appeared.

Under the effect of the spells cast by the legendary mage, both the original buildings in the city and the corpse witch that existed in it will be easily destroyed, and there are few other ways to limit the ability of the legendary mage except to face it head-on.

For this reason, even if it will consume a lot of mana, Rowling has to rely on teleportation and the Aegis of Hercules to bring herself to the sky, trying to use spells to limit the legendary mage in front of her.

Thunderbird, the death knight hero controlled by Rowling, has long been sent by her to hinder the arrival of the post-mage troops, and cannot bring any help in her duel with Phil.

In the face of the real legendary mage, Rowling deeply felt her own disadvantages, whether it was the mastery of the type of spells, or the use of magic, especially for the change of the inherent form of the spell, Rowling was far inferior to the real legendary mage in front of her.

After seeing Rowling come to the sky, Phil did not rush to make a move against the necromancer in front of him, but forced Rowling to consume mana first according to the common fighting methods among high-level mages.

The method of persecution is also simple, Rowling will not let Phil cast a wide range of spells on Ao City below, as long as Phil shows such a move, Rowling will have to preemptively launch an attack on the legendary mage in front of him, thus consuming more mana.

Phil's combat ability is extraordinary, any spell cast by Rowling can be easily dissolved by it, even if Rowling casts a high-level spell, Phil can use a teleportation to distance himself and get out of the scope of the spell, Rowling has to spend more mana in order to keep up with Phil's position.

Perhaps feeling that there was still strength left, or perhaps to force Rowling to cast spells again, in between battles with Rowling, Phil found the right time and cast a number of large-scale damage spells towards Ao City below.

Even if you count these spells cast on Ao City, the mana consumed by Phil is still much smaller than that of Rowling, and counting Phil's own spell casting ability, this is undoubtedly a great advantage.

Even from the perspective of rank alone, Phil, who is a legendary mage, is much stronger than Rowling, but after perceiving Rowling's heroic identity, in the process of fighting, Phil still chose the most secure way of fighting, using his advantage in spell-casting ability to consume the opponent's mana, until the opponent's mana is consumed to a certain extent, and then he will really make a move and end the battle.

cast spells one after another, but it was difficult to achieve any results, feeling the sharp drop in the mana value in her body, for a while, Rowling couldn't help but feel a burst of impatience.

In the course of the battle, some mana-saving techniques that were only mastered by real legendary mages began to be reflected in Rowling's spell casting process.

For example, when chasing Phil, after closing the distance by teleporting, the Hercules shield that appeared under Rowling's feet occupied a significantly smaller area, no longer an elliptical plane, but separated from it, and finally only under Rowling's feet, forming two smaller planes.

In addition, when Rowling casts Hell Flames on Phil in mid-air, she will also limit the explosion range of this spell that can cover a large area, limiting it to just enough to envelop Phil, and the mana consumed will be reduced by several times.

By adjusting the effects of established spells, Rowling saved a lot of mana, especially in a wide range of spells, which was extremely obvious.

Rowling already had this ability to make changes to the Forming Spell, and according to what Rhodes told her, it was supposed to be a unique ability based on the hero's perk, and for orthodox mages, it was only when they advanced to the rank of Legendary Mage that they had access to this ability.

Prior to this, Rowling had tested this ability she possessed, and Rhodes also gave some guidance, including how to use the Hercules Aegis.

In Rowling's impression, according to Rod's words at the time, using this special ability, the mage was able to consume a very small amount of mana and use the Hercules shield to walk freely in the air without mastering the flying thaumaturgy.

At that time, although Rowling understood this and tried it through her own strength, she failed to achieve any results, and Rowling was never able to achieve the effect that Rod said.

Every time she casts the Hercules Aegis, Rowling can't effectively reduce the range of this dark green barrier, at most she only shrinks it by one circle, and the battle is often full of variables, and there is no comfortable spell casting space, and it seems far away to use this ability in actual combat.

In addition to this use, in the hands of some legendary mages, the Hercules shield is sometimes used as a immobilization skill.

To achieve this, the Hercules Shield needs to be folded to eventually limit the creature to it. Although releasing multiple Hercules Shields at the same time can achieve a similar effect, it is undoubtedly more than worth the loss compared to the mana consumed.

When dealing with creatures that are not good at spells, this immobilization effect can be used to the extreme, and the Hercules shield cast by the legendary mage, after countless folds, can fit perfectly into the body of the creature inside, so that it cannot exert any power.

It's just that, in the eyes of the mage, the cage made of the Hercules shield is just a thing that can be escaped by teleportation.

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

Compared with those previous exercises, in actual combat, especially when the opponent is still a real legendary mage, Rowling's ability to control spells has improved rapidly, and the spells she cast, except for the slightly worse panel attributes, are almost the same as those cast by real legendary mages in terms of form.
