The improvement of spell-casting ability has given Rowling a certain advantage in battle, but the enemy she has to face is a real legendary mage.

Phil also mastered this ability to change spells, and the improvement that Rowling got in battle only slightly made up for the huge gap between the two, and failed to recover the previous disadvantage.

Sensing the change in Rowling's casting method, Phil's expression gradually changed, and he began to become solemn, without the feeling of being in control of everything before.

Phil could clearly feel how Rowling's spellcasting methods had changed compared to when the battle had just begun, from the beginning of the ordinary high-level mage's spellcasting level to the level of a legendary mage, and it was also the level of a legendary mage, which couldn't help but make him extremely surprised.

Phil understood that this was most likely the heroic traits of the necromancer in front of him. There are very few heroes among orthodox mages, and Phil has no good means of targeting this unique and powerful ability.

Since the start of the battle, Phil has been silently recording the mana consumed by Rowling, and can always guess how much mana is left in Rowling's body, so as to find the best time to strike.

However, at this point, when Rowling demonstrated this ability, Phil's original prediction was completely disrupted, and he was unable to accurately record the amount of mana Rowling consumed.

Phil's ability to record mana consumption can't play much role in a real legendary mage's battle, because legendary mages can see a very large amount of mana consumption, and it can't be judged by a specific amount at all.

For some reason, in the process of coming to this city of the dead and fighting Rowling, Phil always had a sense of foreboding in his heart.

For Phil, who had long been promoted to a legendary mage, this feeling was something she rarely felt, and the last time she had such an ominous premonition was at the headquarters of the Bracada Magic Guild, the hometown of the City of Mages, and in the City of Magic, when she was shrouded in the forbidden orb.

Although I don't understand why there is such a premonition at this time, but from the undead city in front of him, Phil has already noticed too many anomalies, whether it is the corpse witch hidden in the city, or the heroic necromancer who can quickly improve his ability during the battle, these are all things that Phil could not predict before.

Relying on the united Eri creatures, Phil found the hidden corpse witch and used his own strength to suppress the heroic necromancer, but she didn't know what else was hidden in this undead city.

For this reason, when this sense of foreboding arises, Phil realizes that once the battle continues, something may happen that he could not have predicted, perhaps it is the anomaly of the hero in front of him, or maybe something else.

Through the previous record of mana, in Phil's opinion, the heroic necromancer at this time should have consumed most of the mana, even if he reduced his own mana consumption by relying on the adjustment ability of the forming spell, but he could not make up for the mana consumed before.

After a little anticipation in his heart, Phil didn't plan to continue to consume, and raised his hand to cast an attack spell on Rowling in the air not far away.

In the sky, lightning slashed down on Rowling's head. Feeling the strong mana fluctuations around her, Rowling did not panic, but responded quickly.

In the previous battle with Phil, Rowling had already seen the types of elements that this mage mastered, and most of the spells cast by Phil were more fire magic and air magic, and as for the other two types of magic, Rowling didn't see how to use it.

This discovery also made Rowling judge that Phil was a legendary mage who was good at fire magic and air magic, although she didn't see the pattern of magic elements on her robe, but Rowling was able to clearly confirm this.

Among the two types of magic, the fifth-order magic of the air and fire systems has been cast, the fifth-order magic of the air system provides it with the ability to move freely in the air, and the fifth-order magic of the fire system can allow her to set the entire Ao City on fire.

According to Rowling's understanding of magic, among fire magic, even high-level spells, there are few damage spells that are specifically aimed at a small number of targets, and as the spell level increases, the damage range of fire magic will become larger and larger.

Legendary mages may be able to change this by using their own abilities to narrow down the fire magic that should have been applied to a large area to a certain range, but it still consumes a lot of mana, which is far less than using other types of magic.

Because of this, in Rowling's opinion, it is very likely that Phil used qi magic when he made his move, and not other kinds of spells.

The lightning that fell from the sky also confirmed Rowling's expectations, although she had already applied the air thaumaturgy and fire thaumaturgy to herself, but Rowling had no intention of taking this spell head-on, and instead used teleportation to move to another position in the air.

The lightning struck Rowling's original position, obviously there was nothing there, but there was still a burst of explosion, and in an instant, with the continued condensation of the magic elements, a humanoid elemental creature with a lower body shrouded in a whirlwind, the upper body was purely composed of dark clouds, and the humanoid elemental creature with a faint flash of thunder and lightning in its body appeared at the location where the lightning struck.

Seeing the appearance of this creature, Rowling was stunned, but then the next lightning bolt slashed rapidly, sensing that the danger was coming, Rowling cast teleportation again to avoid the spell.

Another elemental creature, which was produced in Rowling's position just now, relying on the knowledge of elemental creatures in her memory, Rowling recognized that these elemental creatures in front of her belonged to the advanced level of the air elemental people, the thunder elemental people.

Soon, the two summoned thunder elementals launched an attack on Rowling, and huge lightning bolts condensed from their bodies and threw them at Rowling's location.

Rowling was just about to cast a spell to dodge, when she suddenly felt that her eyes were dark and she couldn't see anything around her.

Deprived of her visual abilities by spells, Rowling has no time to cast exorcism spells on herself, using teleportation to evade before lightning arrives.

As soon as Rowling's form appeared, the next moment, a powerful explosion exploded in her position, immediately enveloping her.

By the time the smoke and dust of the explosion cleared, Rowling's form could no longer sustain herself in the air, and without the support of the Hercules Aegis, she began to fall downward.
