Deal with a Devil (Zariel)

For better or for worse, you have decided to contract a deal with an Arch Devil. Whether directly or through a subservient demon, you now have gained great power... at a hefty price. This price is determined by the DM

Once an Angel, Zariel gave up the upper planes to seek great battles. A deal with this devil grants you prowess in combat. You gain proficiency with light, medium, and heavy armors, as well as simple and martial weapons. Your Strength or Dexterity increases by 6, and your maximum for both stats also increases by 6.
