Ring of Osiris

Ring of Osiris(オシリスのリング Oshirisu no Ringu) is a rare and ancient magical artifact that belongs to the royal of the Norvino Kingdom, being at possession of one of the Twelve Royal Knights of Norvino: Sir Drake.

Description
As demonstrated by Drake, the user is able to freely manipulate and control darkness alognside one of its unique properties of gravity. Said darkness is seen as a black smoke that comes out from the user's body, thus devouring and crushing things, with this, the user is able to absorb objects and even attacks of many types just by sucking it like a black hole, this is also used for attracting the opponent to him. Pretty similar to a real black hole, the user absorbs things into a limitness space, however this doesn't destroy or crush whatever is absorved is stored in a strange space. Drake stated he could absorb small villages and even weak mages and thiefs doing some damage to them during the process.

Another major strengthness of this ability is that the user can use his "black hole" at the air and absorb a mix of wind and eternano, thus firing it as a blast at the opponent, Drake can also absorbs water, fire, thunder, clouds, earth objects, and even lava, this is a great advantage in battle or normal situations as Drake can absorbs elemental attacks and even walk under the ocean by only absorbing the water around him ;before this he gathers lots of oxygen to breath. The most major strengthness of this ability is that the user can absorbs eternano from another person upon touch, thus adquiring said eternano for his own magical reserves similar to a eletrical conduit feeding. However this advantage has one major weakness, the victim can get off from the user using his magic as the user can only absorbs eternano from the victim and not restrain him from using it, as the user needs to remain touching the victim to absorb the eternano, the absorption process will stop, however the stolen eternano will not be given back.
