Immortality

Immortality is a radical dark magic ability which allows its user to extend its users life span. Immortality can be performed in many methods but because of the amount of magic that is being used it can destroy ones body. Immortality is one of the hardest abilities to master.

=Methods=

Essence Transfer
Essence transfer is an ability which allows its user to transfer his/her soul into another persons or objects body. This can be done in two ways.

Clones
If the user makes the use of a clone body they could transfer their soul at a moment of death into the clone body. However the clone body is incredibly weak and deformed and is only used temporarily.

Striking with anger!
If a dark magic user can get a powerful magic user to strike them down in anger then their body will destroyed and their essence will be transferred into their killer's body. This can be used to achieve immortality.

Horcruxes
Horcruxes is a banished ability that can only be self-taught, Horcruxes allow it's user to hide a fragment of his/her soul in certain objects in order to become immortal. This requires that the user kills someone in order to create a horcrux.

Dragon Souls
Because of the Dragonborn's ability to consume the souls of dragons this gives the Dragonborn an opportunity of immortality. If the Dragonborn is a dark magic user the Dragonborn can turn the dragon souls into an extralife. However this makes the Dragonborn heavily reliant on dragon souls in an addictive way.

=Rule of Two= The Rule of Two was designed in so the apprentice would strike their master down in anger so the master could live life eternally, this was Henry's plan and would be prophesied that there would be a magic dyad in which the master will live life eternally through the people with the dyad. It is unclear how Henry had figured this out, but it is believed Henry had foresaw the future in a vision. By having the apprentice strike down the master with anger the master's soul would live on in the apprentice, this means that every Dark Lord lives in the current Dark Lord's body.
