None is known about Elle’s abilities. However, one unique thing about her is that her hair is fused with the Formless Darkness, allowing her to control her hair as if it were an extra set of limbs.
Elle is able to summon the dead from purgatory. However, for every pact with the dead, her life-force is drained, decreasing her overall lifespan. Once she summons a spirit, she can never summon them again. By summoning a spirit, she makes a pact with them: one favor, one answer. For her to get an answer for any question she asks, she is required to complete a spirit’s favor.
