In Rhodes' impression, due to the unique effect of the Spiritualist Tower, in addition to channeling the death energy in the surrounding area, this special building naturally has other uses.

In the area where the tower exists, some necromancers who try to improve their spiritualism will choose to pay a certain price in exchange for entering the quiet room of the tower in order to obtain the qualification to perceive the energy of death.

The Soul Tower with this special effect is the most important place to improve necromancers in the city of the dead, in addition to the Necromancer Academy and the Magic Guild.

However, according to what Rhodes observed, this does not seem to apply in the City of the Dead.

Due to the special environment of the City of the Dead, in Rhodes's opinion, the number of necromancers in the entire City of Death is not large, and it can even be said that it is extremely rare, and instead of them, there are extremely large number of undead creatures.

In this case, according to Rhodes's prediction, there may not be many necromancers who will be able to enter this Spiritualist Tower, and the internal structure of the Spiritualist Tower may be partially changed as a result, and there will no longer be a large number of ashrams, but some other things.

Even so, in Rod's sight, this Soul Tower still seemed extremely large, and in Rod's opinion, the real effect of this Spirit Tower would obviously not be as simple as the rest of the Spirit Towers in Diya's territory.

After Rhodes first came to the City of Death, he noticed the existence of the Spiritualist Tower, which attracted Rod's attention, in addition to the special calls that appeared in his perception, and more importantly, the huge size of the Spiritualist Tower.

As for the anomalies of this Spiritualist Tower, before that, Rhodes might be able to get an answer from the mouth of the city lord Tamik, so as to learn more about this matter.

Rhodes believed that as the lord of the City of the Dead, and having been here for an unknown amount of time, even if Tammik herself was not a necromancer, she must have understood the special things inside the Soul Tower, and knew some changes in the structure of the Soul Tower, so as to be able to solve the doubts in Rhodes' heart.

It's just that the previous Rhodes, because he was very concerned about the specific information of the mission, and he didn't observe anything abnormal from the appearance of the Soul Tower, so he didn't ask Tamik about the information about the Spirit Tower.

And now, even if Rod wants to ask Tamik again, it may be too late, and a very special change has begun to appear on the Spiritualist Tower in front of him while Rod is talking to Sailly.

At this moment, the dark red light that originally flickered regularly on the Soul Tower, as if it had received some instructions, the flickering interval was sharply shortened, and the light emitted by it also became extremely dazzling, and along with this change on the Soul Tower, there was an extremely special death energy.

According to Rod's perception, death energy can be said to be ubiquitous in the City of the Dead, and even appears to be relatively strong in many places, not to mention that there are areas such as secluded mansions and spiritualist towers, even if he doesn't need to deliberately perceive it, Rhodes can also detect this.

And in the surrounding undead creatures, the energy of death is always there, and it is always emitted by these undead creatures themselves. In Rod's perception, there is no area in the entire City of Death, and there is no death energy in it.

Even though there was such a strong death energy in the entire City of Death, Rhodes still sensed the death energy that appeared because of the changes that occurred on the surface of the Soul Tower at the first time, and in Rhodes' perception, this death energy was extremely abnormal.

Compared with the conventional death energy in Rod's impression, this extremely special death energy can not only be described as more refined in one sentence, in Rod's view, this death energy has undergone essential changes.

According to Rod's understanding, compared with the conventional magic elements, the conventional death energy is more disorderly, even if it is a powerful necromancer, it is difficult to make subtle transportation of death energy, and there are only a few spells directly related to death energy, such as death clouds and soul gathering thaumaturgy.

According to the classification given by Master Bracada, death energy should be a type of earth-based magic element, but there is a great difference.

Due to this nature of death energy, the necromancer's casting of conventional spells is not much different from other creatures, and it also needs to use the existence of basic magic elements of each system, even if it is earth magic, it also needs to use earth magic elements, and cannot use death energy.

Rhodes' understanding of this was that the energy of death itself was extremely disordered and could not be used by necromancers to form spells.

With their own spell-casting ability, even if the necromancer can directly convert mana into death energy corresponding to the level of spiritualism, they cannot use this death energy for the formation of conventional spells.

In this regard, the only surprise in Rod's impression is the existence of those lichs.

Unlike regular mages, any spell cast by a lich is made of death energy. Whatever the original type of spell was, when the lich cast, it was filled with traces of death energy.

Not only that, but the Lich can't even do anything about it. The spells cast through them do not change with their will, but are all composed of death energy.

Previously in the Dead Wasteland, Rhodes had observed this in the Lich Stephen's body.

According to Rod's understanding, this kind of compulsion to replace the original magic elements that make up the spell with death energy will undoubtedly cause the spell to lose its original characteristics, and even greatly reduce its effectiveness.

This, in Rhodes's view, is also a restriction on the lich itself, and while it has such a strong strength, it is naturally impossible for the lich to have a spell-casting ability that is not weaker than that of a legendary mage.

In Rod's impression, the reason why the lich was able to achieve this was greatly related to the death energy they possessed after the Endless Night Ritual.

Rod recalled that in his own perception, the characteristics of the death energy that Stephen the Lich possessed, in addition to appearing extremely pure, were more stable than ordinary death energy, just like the perception at this time.

According to the information that Rhodes knew, the death energy possessed by the lich was also the closest to the magical element among the death energy with very different effects.
