Sword of Zariel

Sword of Zariel was an incredibly powerful magical and sentient longsword.

Description
The sword was a longsword forged from celestial steel. As a result, the sword constantly emitted a faint humming sound as well as luminescence.

Powers
The sword could only be used by someone who was chosen as worthy enough by the sword. Once the desired wielder attuned the sword, a dramatic physical transformation occurred. The wielder became angelic, given great beauty and their heart filled good. The wielder's alignment was changed to lawful good. These changes could not be reversed by either interference from a celestial being or magic.

A large pair of angelic wings grew from the wielder's back. They allowed the wielder to both fly and hover. The wielder's eye were changed as well, glowing with a faint silver light. This gave the wielder increased vision, allowing them to see in both magical and natural darkness, detect illusions, polymorphed creatures, shapechangers and made invisible creatures or objects visible. They were also capable of glancing into the Ethereal plane.

As well as physical changes, the sword bestowed other powers to the wielder. The wielder gained full knowledge of the celestial language, their charisma and wisdom was increased and they gained a resistance to both necrotic and radiant damage.

The sword illuminated an area with a radius in a bright, holy light. This light was a bane for fiendish creatures, who found the light painful. The wielder was able to control the brightness, they could dim it or increase its luminosity to cover an area with a radius of. The sword delivered radiant damage to all evil creatures, who became blinded when struck on top of normal physical damage.

The sword was sentient, capable of communicating with the wielder via the transmission of emotion. The sword had the ability to hear sounds and speech, and see in the normal spectrum up to away.
