Totally out of the left field, but here's some homebrew that's been spooking around in my brain for a while:
Reactor-Heart Transplant (••••) (Lanka)
The Infernal kindles the inner flame of mortals to burn with a fraction of her own brightness. Mortals may wither under this gift, but those strong enough to deserve it will survive.
System: The Infernal must spend a mote of Essence each day and roll Perception+Occult to implant it into a mortal or near- mortal (Sorcerers, Formori or Shih are options, Mages, Vampires or other fully supernatural creatures not). The target must make a Willpower roll (DC10 - Number of the Infernal's successes) to accept the Essence. A failure causes a level of unsoakable lethal damage, a botch interrupts the procedure permanently, making it clear that the mortal is not compatible with Infernal Essence.
After the Mortal has gained 15 total successes in his daily Willpower rolls he has successfully adapted the Infernal spark and burns with his own Essence, becoming an Enlightened Mortal. Whenever the Enlightened Mortal uses his Essence he shows minor signs of its Infernal origin, like a small flicker of hellfire in his eyes.
Interrupting this process for a day causes it to fail, though it can be retried later. During the procedure the mortal is feverish, in pain and barely able to rest, he has +2 Difficulty on all actions he takes outside of the daily WP-roll, plus one more if it takes more than a week.
Enlightened Mortal
This mortal has unlocked Essence of his own, most likely through the direct aid of an Exalted, though it is rumored that the secrets of Essence can be tought in mundane training and meditation as well, a process that would likely take years even for the most talented.
The mortal has a pool of Essence as shown in the table below and regains (Essence Rating) Motes each day at sunrise.
The Mortal may now learn Supernatural Martial Arts, Sorcerer Paths or Ancient Sorcery, though learning the last without an Exalted teacher requires twice the usual amount of XP as mortals are not well equiped to comprehend Ancient Sorcery, even if they have a book or another mortal sorcerer to learn it from.
Essence may be used in the following ways:
- Spend a mote of Essence on an automatic success, similar to temporary Willpower (can't use this on the same roll as WP)
- Fuel supernatural powers in place of Mana, Rage or Chi (For Sorcerers, Formori or Shih respectivly)
- While wounded you may spend one Essence per day to ensure a clean and scarless healing of wounds, even absent of medical help. This does not speed up the recovery, only ensures its success
- While sick you may spend one Essence per day to lower the difficulty of future rolls to resist the disease by 1, ensuring eventual recovery for any disease
- For the purpose of age-related penalties and the eventual death, add a decade to the lifetime per Essence-Rating
