Reflection, The Blade of Order and Chaos

You have a +3 bonus to attack and damage rolls made with this magic weapon

Sentience. Reflection is a sentient True Neutral weapon with an Intelligence of 16, a Wisdom of 20, and a Charisma of 18. It has hearing and Darkvision out to a range of 120 feet.

The weapon communicates telepathically with its wielder and can speak, read, and understand Common, Celestial, Infernal, as well as the languages its attuned wielder knows.

Personality.  Within Reflection is a strange living energy, holding the sword almost feels like placing your hand against the gentle beating heart of another living creature, Reflections personality adapts to the creature wielding it helping them fulfill their goals by changing them to who they truly are.

This blade binds to creatures who attune to it, drawing energy from their identity. A creature who does not meet the attunement requirements of Reflection may still attune, but if they do so, then once every 8 hours, they take 10d8 force damage and gain a level of exhaustion (exhaustion inflicted by this trait cannot exceed 5 levels), as the blade tugs at their soul, past, and essence. If affected by this backlash, a creature cannot willingly unattune from the weapon.

If the damage caused by backlash reduces its attuner to 0 hp, they become stable immediately, and are also stunned, forced to relive their past. The creature can escape this stunning effect by succeeding on 3 Wisdom saving throws, made once every 8 hours at DC 25, or by being the subject of a greater restoration casting. If the creature fails 3 of these Wisdom saving throws before it succeeds 3, then their alignment becomes either Lawful Good, Chaotic Good, Lawful Evil, or Chaotic Evil (creature's choice), and ceases to be affected by the backlash.

Once a creature has fully attuned to Reflection they gain a telepathic bond to it, learning how to wield its magic power, they may willingly unattune as they wish, if a creature that unattunes to reflection had their alignment shifted, they may choose to restore their original alignment upon unattuning.

When a creature attuned to Reflection deals damage with it they may expend any number of its 5 charges to deal 1d8 damage for each charge expended, its charges reset at Dawn. The type of damage is determined by the attacking creatures alignment.
* The extra damage dealt by a Lawful Good character may be force or radiant.
* The extra damage dealt by a Chaotic Good character may be force or thunder.
* The extra damage dealt by a Lawful Evil character may be force or fire.
* The extra damage dealt by a Chaotic Evil character may be force or necrotic.

Proficiency with a Greatsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
