"Original magic energy, this is the conversion of spells into original energy. The essence is that the conversion is performed simultaneously while casting the spell."

"Under normal circumstances, it is impossible to cast legendary spells at the same time as other spells, and also to convert them into raw magical energy!"

so……

Isaac thought for a while and temporarily put aside the idea of ​​"original magical energy".

This operation is basically only used in the "ritual magic circle". It is unlikely to be used by individual casters.

Therefore, it will naturally not become the entry point for "modifiable" elements.

This idea was ruled out.

Isaac then continued down.

"Withstand the blowback"!

This "element" has been regularly incorporated into his professional ability "Exceeding Limit Casting 1".

Isaac's mastery and understanding of it is extremely profound.

He only pondered for a moment, and soon shook his head again.

If ordinary legendary mages also have this "modifiable" idea, they may invest a lot of energy in researching this aspect.

But his "scientific system" has already completed the theoretical induction of various factors. In his research...

"Withstanding the backlash, this is just a late correction after the planning of the legendary spell is completed."

"And the 'modifiable elements', whether it is changing the spell intensity or changing the opening of the 'slot', should be directly involved in the planning of the legendary spell!"

"So, 'bearing the backlash' won't work either!"

Again one direction is excluded.

Next…

"Since the 'modifiable elements' are involved in the planning of the legendary spell, then..."

“Two main ideas!”

"One, the 'redundant spell knowledge' brought about by the improvement of professional level!"

Isaac's eyes narrowed slightly, and in the darkness, there was a "flash of lightning" brightness blooming in it.

This idea, in theory, should be achievable.

Moreover, this essence has long been reflected in his "Exceeding Limit Casting 2".

but……

He continued to think deeply, and slowly, he shook his head slightly.

"The theory can be realized, but...the practical application is meaningless!"

For legendary spells, you must first be able to master level nine spells, and then your career level must break through to level 21, and you must master the legendary expertise of "Legendary Spellcasting" before you can research and cast it.

However, after the caster level reaches level 21, how many more people can there be, and how many more levels can they continue to improve?

With each level of improvement, the "spell knowledge level" is only increased by one level.

After deducting further deductions, even if "modifiable" can be successfully researched, adding this element will require an additional "difficulty level"...

Therefore, the actual significance is not great!

It can even be said that it is almost nothing!

"The focus should still be on 'sacrifice career accumulation'!"

The accumulation of sacrificial professions is also a plan that most legendary mages must make when improving their spell strength or adding "instant cast" corrections.

In comparison, such as Isaac, or some dragons who have mastered legendary spells, especially the original dragons, have a natural and huge advantage in this regard because of their high enough life energy level.

Therefore, Isaac has never included this "element" in his research.

Of course, he has not had enough "career accumulation" to squander it in this "magic casting process"!

But at this time...

"Career accumulation, whether it is the feedback from the 'magic essence', the endowment from the 'dragon origin', or other career sources, fundamentally, it is all a kind of influence on oneself.

Essence's enhancement!"

And since it is related to "essence"...

Isaac didn't think about it and just went straight to squander the professional accumulation he had been eager for.

After all, compared to Laila, compared to Kelben and others, he lacks a lot in terms of "time accumulation".

So, since there are deficiencies in this aspect, it’s time to change your thinking!

"The Witch King's Clone Cabin!"

"Helast's Leyline Maze Barrier!"

"The legendary Elf Mystery Lock!"

"Even... the Lich Phylactery of the Lich Ritual!"

Isaac only had a brief thought in his mind, and a series of ideas jumped out.

All are related to "essence"!

He already has a deep understanding of all of them, or at least has enough guesses. In the "topic registration", there are topics corresponding to them!

"The key to 'modifiable factors' lies in 'career accumulation'!"

"The transformation of 'career accumulation' should correspond to 'essence'!"

"The 'essence' is also related to the planning of the 'terminal'!"

"If we can design an idea that replaces 'career accumulation' with 'essence' and supplements its loss..."

Isaac's eyes flashed.

To a certain extent, whether it is "Earth Maze Barrier" or "Elf Mystery Lock", from the perspective of its "self-repairability", it means "replenishing losses".

The "Lich Phylactery" automatically reorganizes the body after death, which is also interesting.

With his mastery of the "Litch Ritual" and his exploration and understanding of the "Line Maze Enchantment", from a theoretical point of view, it would be impossible to design a special "legendary spell auxiliary prop".

Too big of a problem.

The only thing to consider…

“It should also be combined with the inspiration of the Witch King’s ‘Clone Cabin’!”

"There is no need to completely transform into a lich, nor has it reached the level of sublimating one's own essence towards the 'Legendary Seed'!"

"So, it is more appropriate to design a ritual, peel off part of the essence, and use this as the core to create an auxiliary prop that has a similar principle to the 'Lich Phylactery' and can be 'charged' after use!"

"And because of the consistency of its 'essence', this item can be regarded as an extension of myself, and therefore can be applied to legendary spells at any time!"

"Even if you don't design a 'modifiable element', normal legendary spells can still use it!"

Isaac's spiritual awareness was bursting out again.

There is a feeling that this "auxiliary prop" with the nature of "self-extension" can not only be applied to legendary spells, not only can it assist the design of "correctability", but even...

"Clone!"

"Even him I incarnate!"

"This is the premise and it is also an important accumulation of research in this area!"

One thought leads to everywhere.

From "correctability" to "auxiliary props", Isaac's inspiration that condensed and sublimated countless wisdoms instantly unified his many subjects into a whole.

Moreover, since in theory, it is completely possible to realize it, then...

Calculating the time in his mind, Isaac was not in a hurry to catch up with Barrett and others. In the darkness, Isaac narrowed his eyes again.

Lich Ritual!

Lost City Enchantment!

Reincarnated body!

The essence of various rituals and various realms is constantly summarized and combined in his heart.

…

And this at the same time.

Opposite the Skull Port, there is also the "Dark Maiden Corridor" directly connected to the "Sagas Layer" of the Leyline Maze.

In front of the temple, under the huge statue that combines the temperaments of "Kuilu" and "Eilistraee".

Believers of the Dark Maiden.

There are drow, humans, dwarves, gnomes, and even halflings and half-orcs.

At this moment, all the people had solemn expressions, and quite a few of them had various degrees of injuries on their bodies.
