In addition, demons usually possess drastically enhanced levels of strength and stamina, due to how durable their body has become, allowing them to resist tearing muscles or breaking their bones.
 * Weapon Creation - Demons can create weapons from nothing or by shaping the existing matter or energy, they are capable of creating virtually any weapon and however many they wish. Depending on what the weapon is made of, it can possess a variety of abilities and be very effective in both offensive and defensive combat.
 * Possession - Demons can inhabit or take over the body of any living being, whether sentient or not, by stealing their motor functions and senses. Users may or may not have to leave their own body for this to take place. Disembodied users such as spirits may use the body as their own.
 * Poison Creation - Demons can generate, create, emit, or otherwise produce poisonous substance and somehow inflict the victim.
 * Blood Magic - Demons has the inherent power in their blood to manipulate and/or fuel spell-casting. This is an ancient version that predates word-based magic and was considered by some to be more powerful. Blood Magic was a kind of magic based on the employment of blood which is an important component in many rituals, spells and other aspects of the supernatural world.
 * Immortality - The race of demons possesses immortality: an infinite life span, as they can never die, never age, and can shrug off virtually any kind of physical damage. Some users are the defensive type, simply preventing all damages, to appear physically invulnerable, while others are the regenerative type, surviving and quickly recovering from anything you throw at them while at the same time they are capable of resurrecting themselves instantly after death and completely self-sustaining, free from all bodily necessities.
