Devour

Call upon your Fiend Patroc.
By eating the hart or drinking the blood of a Fiend I can learn one of its skills, abilities or powers.
Roll a 1D20. On a 10 or higher you can choose to learn this skill/ability/power on the cost of half of your current health.
The DM decides what skills, abilities or powers are allowed for you / able to be devoured.
If no skills, abilities or powers are available you still lose half health for using this ability.
