Aethana's Blade

Starts as a standard, black iron, long sword, with standard long sword stats.

After killing its first enemy and judged as being worthy by the residing spirit of Aethana, white, wispy mist, streams from the enemy into the blade, igniting and wreathing it in purple ethereal fire. After the flames recede into the blade, revealing a transformed white sword underneath.

It is revealed as a sword that has a white blade with a silver edge, engraved fiery red feathered wings with a gold edge, are on the side the blade, leading towards the collar that has 4 helical arms leading from the top to the edge of the circular guard stylised like a golden wreath, and an ornately wrapped handle, with a red dragon hide underneath and white cross wrapping (Katana style) with a standard white and gold rimmed pommel marked with a black 8 pointed star on a ruby inset (2 overlapping squares with one at a 45 degree angle)

The blade can also hide itself, in a gout of soul fire, reappearing as a standard, black iron, long sword, doing so empty's the soul reservoir, but hides its true nature.

When the wielder has the intent of killing and enemy (prevents use by people who aren't committed to the defeating an enemy) The wings shimmer with purple flame and, the octagram glows with golden light and white mist is emerges from the blade and wraps around it before igniting with trailing purple soul fire.

Each soul absorbed from the swords slain enemy's add their CR (ignores AC below 1) to the soul reservoir, which can be expended as bonus damage, the soul reservoir can store a maximum of 18 soul energy, increases by 5 per each player level above 1. 

Each attack inflicts 1d8 slashing damage, +2 to hit, before making an attack you can choose to add 2d12+5 psychic/fire damage (expends soul energy, in the reservoir if fully depleted, the bonus is equal to remaining soul energy) using a bonus action, causing the fire to burn brighter and more focused at the blades edge. Advantage to hit fiends or the undead.

Can launch a soul fire charge from the blade, +1 to hit ,that inflicts 2d8+5 psychic/fire damage (expends soul energy, in the reservoir if fully depleted, the damage is equal to remaining soul energy), with a range up to 80ft. Advantage to hit fiends or the undead.

The blade contains the holy spirit of Aethana, who is an Archangel, demon slayer, and is sealed within the blade and can be released temporarily or can speak to the attuned wielder, if they are "Worthy of being guided" and being lended their power of soul fire.

Spells such Detect Good and Evil (Good), Divine Sense (Angel) will be triggered by the blade in its revealed form.
