After Zhao Xu obtained the "Spell Upgrade" specialty, the corners of his mouth couldn't help but smile, but at this time, there were two cavalrymen leading the way in front of him, and there were no people walking side by side, so naturally no one knew what he had gotten.

In terms of level expertise, Zhao Xu had to wait until level 9 to obtain the next specialization, and in terms of the difficulty of upgrading at level 6-9, it was likely that he was already close to crossing over.

The remaining chance, when he is promoted to level 7, can obtain an additional super magic specialty when he is promoted to level 2.

A common mage needs to be level 5 to gain the Hypermagic feat.

The Super Demon Shaping Method enables Level 1 to gain the "Super Demon Control" ability, and Level 2 to obtain the Super Demon Specialty, which is where the strength of the advanced profession lies.

But after all, his specialty is very rare.

For example, Zhao Xu didn't have a choice, such as "Spell Extreme", which can make the fluctuation range of spell damage the maximum, or "Spell Strength", which can increase damage by about half.

He directly chose "Spell Upgrade" because this specialty could reach an unsolvable power in his hands.

For ordinary people to successfully resist spells, one is to rely on immunity, and the other is to rely on spell resistance.

Unless the spell pierces immunity or ignores resistance, which is extremely rare in its own right.

Instant death spells like "Blasphemous" have become a powerful killer just because they can ignore immunity just because they are above level 10.

And ordinary people basically don't have the existence of spell resistance, so they are naturally powerless to resist in this regard.

Therefore, whether ordinary people can survive the spell mostly depends on whether they can survive the exemption.

Zhao Xu received an education in this area when he received a magic combat class from Antinoya.

If you want people to be unable to resist spells, you can either use spells without immunity, or you can pile up your own spell immunity difficulty to the point where others can hardly pass it.

The general spell immunity difficulty is based on the 10th tier, superimposing the intelligence adjustment value, and then superimposing the number of spell rings.

In terms of Zhao Xu's 22 points of intelligence, his spell immunity difficulty is 16+X ring.

For example, the Triple Ring Fireball Reflex Exemption difficulty is level 19.

In terms of the ability of civilians, the reflection immunity provided by the profession is almost 0, and the superposition of agility attributes is even more pitiful, so it is basically relying on the reflection immunity base of the 0th level, and then superimposing the temporary performance of the 1-20 level to resist.

Therefore, Zhao Xu's fireball technique is for civilians, and the opponent can only reflect successfully if he plays a perfect 19th and 20th order, and only takes half of the damage.

As for some monsters with more than 20 levels of reflex immunity, Zhao Xu's fireball technique is basically inevitable for the other party to pass.

However, in terms of immunity difficulty, it is extremely difficult to improve intelligence.

Therefore, the general caster can only choose some specialties that specialize in spell factions to increase the difficulty of the corresponding faction's spell level 2.

It can only be said that talking is better than nothing.

On the other hand, it is possible to use the means of "spell upgrade" to improve the ring spell and increase the difficulty of the spell's exemption.

For an existence like Ryan, if he learns the spell to upgrade the level, he can use the Nine Rings spell slot to prepare the Fireball Technique, so that the number of rings superimposed on the difficulty of the Fireball Technique is the Nine Rings, which is equivalent to increasing the immunity difficulty of the entire 6th order.

The two designated Shaping faction's Spell Specialization and Advanced Spell Specialization are only Tier 4.

In addition, after leveling up, you can also bypass the restrictions of "secondary spell nullification enchantment" and "spell nullification enchantment".

Once Zhao Xu was in the passage of the dungeon, in order to avoid a bunch of three-ring spells in the spell turret, he used the "Spell Void Enchantment" in the protective staff, which directly made him immune to 1-4 ring spells.

Later, when Zhao Xu was transformed or the angel was in tune, the "protective aura" carried by the angel itself was also combined with the "secondary spell invalidation enchantment".

It can be said that the 4-ring mages directly suppressed them, the mages of the 1-3 rings, to death.

But after having a spell upgrade, Zhao Xu only needs to upgrade the spell to the fifth order, and he can bypass the restriction.

However, in any case, the number of people who choose the easy-to-learn specialty of spell leveling is not many after all.

Because, the cost of ring surgery is too severe.

A three-ring "human immobilization technique", and the superimposed spell is instantaneous, which also occupies the seven-ring spell slot.

But the same "group human immobilization" is only seven rings.

If you upgrade the human immobilization spell to the Seven Rings, you will get nothing but the difficulty waiver.

Not to mention, the premise is that Zhao Xu currently only has a three-ring spell slot at all.

He just upgraded the spell from zero to the second ring to the third ring, and he couldn't get rid of the spell invalid enchantment.

As a result, casters with "Spell Upgrade" are common.

However, at the same time, Zhao Xu, who is also "controlled by super magic", is incomprehensible.

He can choose to upgrade the spell to the X level, but the specific cost of the ring spell is achieved by the super magic control ability to take X attribute damage.

Then, theoretically, he can use "Energy Protection" to make X-point attribute damage immune, as long as he uses six different attributes afterwards and refreshes the spell.

However, Zhao Xu knew that there were two regrettable limitations.

He can't arbitrarily increase the difficulty of spells by hundreds of millions of levels.

Because his attributes are limited, this X-point attribute damage cannot exceed his attribute value, and if it is put into the highest 22 intelligence attributes, it cannot exceed 21 attribute damage.

At the same time, there is another point, that is, the premise for Zhao Xu to cast the Nine Rings spell is that he must have 19 intelligence.

So his current 22 intelligence points also means that he can cast a maximum of twelve ring spells.

This means that all of his spells can be upgraded to a maximum of 12 rings, corresponding to an exemption difficulty of 28.

Instead of raising the twenty-first ring as originally expected, the difficulty reaches level 34.

This is also the reason why the next "+6 intelligence bandana" means a lot to Zhao Xu. In addition to increasing the difficulty of the 3rd level of immunity from intelligence, it can also increase the 6th level from the ring number, so that Zhao Xu's spell exemption difficulty can reach 37 levels.

However, it seems that he is now within reach of the 28th level difficulty, which already means that ordinary mages have a ceiling that is difficult to reach.

In terms of the old ghost woman he might encounter, if he wasn't stronger, it would be 12th level of toughness, 9th level of reflex, and 10th level of will, and it would be extremely difficult to be exempt from his spells.

However, the opponent has a 25-level spell resistance, and in the face of his Zhao Xu's level 12 spellcaster, there is still half a chance to resist his spells.

As for other players like the current one, with their caster level not exceeding level 3, it is basically impossible to break through the old ghost woman's spell resistance.

It wasn't until the cavalry in front of them used the long sword in their hands to remove a lush weed, that Zhao Xu and his party finally saw an old house that looked very dilapidated and showed signs of collapse.

And judging by the blackened walls and the charred remains, I am afraid that the house was burned down again, and finally covered by the traces of time.

In the wilderness, it is a little strange that this kind of single-family house suddenly appears.

Especially Arthur, because of the existence of a large number of monsters, basically all races will choose to live in groups, and most of those who can live alone have "abilities".

And the house itself is a certain distance from the cemetery, so it will not be a grave keeper's house.

Zhao Xu began to slow down, trying to get closer.

At this moment, Chuck, who was still a little dazed, suddenly changed his face, and directly grabbed Zhao Xu and said, "Mr. Pastor, I suddenly remembered a legend. ”

Zhao Xu turned his head and looked at the other party at this time: "Huh? ”

And Mrs. Betty stopped talking at this time, but after all, she didn't say much.

Chuck, who served as the captain of Mrs. Betty's bodyguard, reached the level of a first-class warrior in his thirties, which is not outstanding, but with his sturdy physique and tendon meat with huge arms, it is basically easy to eat.

With a look of remembrance, he thought for a while and said, "When I escorted my wife back to Frostdew Town, I heard the children there sing nursery rhymes. ”

"Keywords like old houses, graveyards, hide-and-seek, old witches and the like."

As soon as she finished saying this, Zheng Xinyun's scalp almost went numb, so she couldn't help but stand close to Zhao Xu.

The dilapidated houses and cemeteries have all coincided with the current scene.

Suddenly, Zhao Xu pointed to the two cavalrymen in front of him, "I see the house, you two go and stand behind me." ”

If the old house in front of you is indeed the residence of the old ghost woman, then there is really no need to send people to death.

At this time, Zhao Xu lowered his head and pondered, the old ghost woman's attack was counted as a magic weapon, which happened to be able to penetrate the defense of his star cloak.

At first glance, although his defense was superimposed on the mage armor level 4 and the shield technique level 4, only the 18th level was still difficult to defy the sky, and he was still under the threat of the old ghost woman.

The Tier 1 defense that originally came from agility was offset by his vulnerability.

However, Zhao Xu, who is a three-ring spellcaster, has the ability to master super demons.

He already has the ability to stack static defenses.
