These medicine pills were created from the remains of the demon Diablos, which was severed by the Three Heroes. The cultists greedily wanted the demons power and began to perform experiments with its remains. To their research discovery, the demon remains possessed an incredible vitality and was able to instinctively move and regenerate.

From then on, they created what would be known as the "Tears of Diablos" and their different types from the incredible life energy that contained within Diablos Cells. The medicine pills still had side effects, but unlike before, it was effective on men now as well. Nelson was one of the original 12 members of the cult "Knights of Rounds" who helped, organized, and collaborated in the creation of these pills and their derivatives.

Types of Diablos Tears
Over time, the Cult has used these drugs to support their endeavors, but the source of their true strength lies elsewhere as they engineered these Tears from Diablos' life force on the flesh and blood to increase mana power. But, come with the risk of destroying one's body and mind if they aren't already strong.

After spent numerous years for researching and experimenting on its remains for ages, they were able to developed various types of pills to increase the magical power of its organization and its members. So far, there are 2 types of Diablos tears have been known.

Normal Red Pill of Diablos Tears
These are normal red pill (赤い錠剤) which is an unfinished products, made from Diablos Cells with strong side effects during development which are also has been manufactured in large amounts on production. The pills are distributed to the strong members of the Cult of Diablos, usually to the first sons and second children, also the "12 Knights of Rounds" usually take them.

But these pills have flawed, since the side effects of these pills are too strong for the body, even if one of the cult has the requisites to handle and control such magical power of these, while mutating them into something inhuman. Those of the Cult of Diablos considered them as a semi-failed experiment.

And they used these pills only as a temporary enhancement support that will boost their abilities by increasing a person's magic power, body size and muscles for their high-ranking servants, since they did not give the result that they really sought, which was immortality. Until now, Grease, Zenon and a cult ally, Gettan, have used them to achieve their goals.

Pearls of Diablos
These are special pills that grants enormous demonic magical power, maintain vitality, as well as immortality of whoever eats them. These pills are reserved only for the 12 highest members of the Cult who held the executive position of "The Knights of Rounds".

Unlike the normal one, the production of these are very difficult and the number of drops is very limited due to scarcity of Diablos Cells. The total amount is precisely 12 drops a year, which is the exact same number of members in "Knight of the Rounds".

Furthermore, these tears are not perfect because if they are not eaten annually, then the power of the person who eats them will greatly reduce both his magic power and his longevity. These Pearls were made from 2 main ingredient, which is the "Diablos cells" that are cultivated from the demon's body and the hero's descendants blood.

Potential Power and Side Effect
These pills cannot be consumed by normal people with little magical power, be it a human, elf or half-beast, as these pills contain tremendous demonic power. if they consume it, it would deform the one who eats them until they break under this power and die from the tremendous supercharged magical power that eventually lead the self-destruct on their body. But those in the "Knights of Rounds" are different, because only those who can manipulate this devastating power by controlling it have the right privilege of joining the Rounds.

These pills grant great raw demonic magical power, which increases the strength and speed of the Diablos cult members who consume them with the possible side effect of metamorphosis mutations depending on race and surpass all limitations, also a rapid regeneration and high resistance to inflicted pain called "Third Awakening". Until now, it was unknown what else it grants at the level of use of spells and enchantment, apart from the fact that its effects were temporary.

In general, a part of these pills can exert a great increase in magical power. But, by eating many of these, it can causes whoever ingests them undergoes a metamorphic transformation in his entire body, sometimes even fusing with the weapons they carry.

Another effect of these pills is that its enhanced effects didn't last long, whether a few or many that are taken, they have a limited period of functional time. The moment its effects ended, whoever consumed it would return to their normal state, not to mention being exhausted by the immense power exerted by the pill, leaving them with little strength to fight. As seen in the case of Gettan after being defeated by John Smith who despite his altered body condition by consuming many of these pills, he returned to his normal appearance, but with little strength to fight plus the exhaustion he had which ultimately led him to his death due to the serious injuries he sustained.
