Due to the physiological strain the body undergoes during the transformation, Curse Beings are considered "Reborn." Therefore, they are usually granted a new lifespan of 100 years, with their patron adding or removing life force as they please. In theory, a Cursed Being could live forever, provided they please their patron, and don't get killed.

Due to their previously human nature, Cursed Beings do not have a set alignment. They may fall anywhere, but are often assumed to be evil because of their new bodies. 

Curse Beings are often taller than their previously human selves. Most fall between 6 and 7 feet tall. Your size is Medium.

Your base walking speed is that of your previously Human self. 30 feet is your walking speed. 

Due to your nightmarish physique, and extreme rarity, most people do not understand what you are and will treat you as such. You likely will be met with stares, discrimination, and fear. However, those that do know what you went through in order to become a Cursed Being will likely have a twisted sense of respect for the pain you endured, and the willpower it took in both body and mind to overcome the transformation.

When you gave up your body for power, you underwent physical changes. This allows you to better attune your new body to your new power, adding +2 to one Ability Score, and +1 to two ability scores. 

Your body underwent physiological changes as part of your pact with your patron. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

As a result of the physiological changes within your body, you are seen as nightmare fuel. You gain proficiency in Intimidation.

Due to your overflowing knowledge granted to you by your Patron, you are able to read and write: Common, Abyssal, and one language of your choice. 

Because of the wings that you have been gifted, you have a flight speed of 30 feet. 

Due to the overwhelming pain of transformation, you are naturally tolerant to pain. This is evident in your armor class adding your constitution modifier when unarmored.

Because of your new body, you have some new weaknesses as well. You have vulnerability to Cold and Radiant damage.

As part of your transformation, you are granted a second heart. This heart allows you once per long rest to keep your HP at 1 in a situation which would typically knock you to 0. This ability also allows you once per long rest to be knocked directly to 0 HP instead of instantly dying when hit with damage that is more than double your HP. If you are hit with damage that is more than triple your HP, or the damage being dealt is Radiant damage, this effect does not work.
