All Devils ranging from High-Class to Low-Class are able to use this form of power, letting them both create and control different supernatural phenomena for different forms of combat. There are some unique demonic powers that inherited among the different 72 Pillars and the Extra Demons, which no other devils outside their respective clan are able to use. Due to their members being married to other clans, the children born form the union of fellow pure-blood devils can manifest the powers of one of their parents, as was the case with Venelana Gremory (née Bael); who married into the Gremory clan, which allowed both her children; Sirzechs Lucifer and Rias Gremory, to inherit her Power of Destruction.
In order to use demonic power, it has been described that a devil must first acquire the power of imagination, the power to create and good sense; however, the main prerequisite for all this is, is that it requires a certain amount of demonic power. Members from Noble Devil Clans such as the 72 Pillars are born with greater demonic power compared to that of normal devils to the point where it's rare for them to train in using their demonic power. Most notably the relatives and descendants of the original Four Great Satans are born with demonic power far superior to those from the 72 Pillars, with the Lucifer Clan being the strongest ones in terms of demonic power.
There are rare occasions where devils outside of the original Satans, such as the case with the current Four Great Satans, have demonic power that equals or surpasses them. Another individual who was born with an immense amount of demonic power is Diehauser Belial, the current Rating Game champion, who's power is stated to be equal to the current Satans.
On much rarer occasions, Super Devils, irregular devils born with demonic power exceeding the original Four Great Satan, including Lucifer himself, making others doubt whether or not they're devils. Among them is Rizevim, Sirzechs, and Ajuka. Sirzechs and Ajuka, in particular, have power reaching the Top 10 Strongest Beings; the former in his true form surpassed Hades, and the latter was confident in front of Shiva.
Though it is natural for demonic power to manifest in all devils from birth, there are rare cases when devil children have difficulty controlling theirs, and even those who are born lacking demonic power. This is even the case with High-Class Devils such as Sairaorg Bael, who was both born with little demonic power and lacked his clan's unique power.
Due to the pride of the upper echelon of the Underworld, High-Class Devils looks down on those who're born with low demonic power, including their own family members. This was most notable with Sairaorg, a pure-blood devil from the Bael Household who was exiled by his own father in the remote regions of their territory with his mother to prevent other devils from learning about his condition.
It is possible for a devil's demonic power to be increased through constant training, but the exact method of doing so is still unknown. Outside of training, there are methods of increasing one's demonic power ranging from using Ophis' Snake or using the King Piece; a special kind of Evil Piece which enhances demonic power by a factor of 10 to 100 times.
Devils have a weakness against the light powers of Angels and holy items related to the system established by the Biblical God. However, Devils who have higher amounts of demonic power can develop resilience against this property of holy weapons and objects.
