Commandment

A is a unique power created by the Demon King over 3,000 years ago. There are ten in total and each has a unique curse bestowed upon anyone who breaks its rule.

Overview
The Commandments are a set of ten decrees that were created by the Demon King when he took half of his power and split that into ten fragments to create the Ten Commandments, who derive their group name from their powers.

Each Commandment has a specific rule that, if broken, will place a specific curse on the victim(s) depending on what the Commandment itself is centered around. The power of the Commandments is absolute and affects anyone who breaks its rule, even the wielder itself. However, anyone who has another Commandment is immune to all others except their own. Those who were given a Grace or a divine blessing by the Supreme Deity are also immune to the Commandments’ effects as well.

The curses will only be lifted if the victim defeats its wielder or at the victim's death. The Commandments can be removed from their wielder using a special spell, but only if he or she gives their consent or if they are left powerless, unable to fight or die.

Absorbing a Commandment turns any non-demon race into a demon, giving them the standard demonic powers as well though in the case of a goddess while gaining such powers, their souls and minds would be devoured and warped by the Commendment due to being the polar opposites of demons. Though Mael, the only goddess to receive a Commandment, was bestowed one after his memories were altered by Gowther and his doll so it’s unknown if the same effect applies if he had his real memories intact. Moreover, if anyone, demon or not, tries to take in more than one Commandment, it would destroy them. Monspeet himself said only the sons of the Demon King, Meliodas and Zeldris, could survive such a feat, but it is revealed that Mael as Estarossa is capable of doing so too, but at the cost of warping his broken soul and mind even more and in the end going crazy.

After Gowther’s memory spell wore off and Mael regained his memories, his body holding three Commandments took on mixed a appearance of a goddess and a demon where his left half is that of a demon and the right is that of a goddess. In this form, he’s able to use both his holy and demonic powers and even combine them together. After absorbing a fouth, Mael was able to materialize the Commandments in physical forms ans use them for various attacks.

Meliodas states that by absorbing all ten of the Commandments, he can reach a level of power equal to that of the Demon King and Supreme Deity, as he is doing so to end the curse placed on Elizabeth Liones.

Techniques

 * Mael takes the Love Commandment and uses it to create an incredibly destructive explosion. The effects of the Commandment turns any pain and suffering in the opponents into pleasure, lending them to grow sleepy and finally die.
 * Mael takes the Truth Commandment and uses it to create a bell capable of dispersing any illusion.
 * Mael takes the Reticence Commandment and uses it to craft a scythe that brands anyone hit with the cursed seal of the Commandment, sealing their magic.
 * Mael takes the Purity Commandment and uses it to create a big incense which smoke make people to be immobilised by a great preassure and suffer hallucinations of what their hearts truly desires.
