Agony's Duty

This magical greatsword bears the pain of loss. As you lift it, you can feel the weight of its prior owner's sins. You have +1 to attack and damage rolls with this magic weapon. You can use a bonus action to speak this magic greatsword's command word, Drishti, causing blue flames to erupt from the blade. While the blue flames remain active, this sword deals an extra 3d6 fire damage to any target it hits. The flames lasts for 1 minute or until you use a bonus action to speak the command word again or until you drop or sheathe the sword.
Wrath of the Flamescion A wall of blue flame appears around you, harmless to yourself and up to 7 friendly creatures. It extends 15 feet from you in all directions, stands 10 feet tall, and is 1 foot thick. When the wall appears, any non-marked creatures within its area must make a Dexterity saving throw. On a failed save, a creature takes 3d8 fire damage, or half as much on a successful save. One side of the wall, selected by you when you cast this spell, deals 3d8 fire damage to each creature that ends its turn within 5 feet of that side or inside the wall. A creature takes the same damage when it enters the wall or ends its turn there. The other side of the wall deals no damage. The Wrath of the Flamescion ability can be used once per day, costs a bonus action to summon or dismiss, and will automatically end after 1 minute.
Drishti's Embrace Blue flames erupt from the sword and cling to your body, hardening into a dark obsidian shell that protects you from all physical damage until the start of your next turn. However, in doing so, you become vulnerable to magical damage while the shell is active. Additionally, you recover 1d10 hp at the beginning of your next turn as the obsidian shell cracks and molts off. Due to the weight of the shell, you sacrifice all remaining movement and actions/bonus actions on the turn you used this ability. This ability can be used a number of times per day equal to half your proficiency bonus rounded down.
Proficiency with a greatsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
Notes: Damage: Fire, Damage, Combat, Heavy, Two-Handed

Lore

Suddenly, my eyes opened. The life that I had thought to know, simply a dream cast aside by newfound sapience. I stood on the vestiges of shaking legs and dressed in my formal tailcoat, slowly leaving behind the nightmare that had consumed me for so long. The mirror found a slight smile upon my face as I affixed the bowtie to the front of my shirt before setting out for the grand hall.
I saw her, then, so elegantly shifting her golden bangle along her right wrist, eyes cast to the floor. She didn’t want to be here any more than I did. Slowly I approached with a smile, dipping my head low in a soft bow, aggrandizing the occasion sarcastically. She caught my eyes and laughed sweetly. And I knew, somehow… I knew that from that moment, I would pursue her until the end of time.
Her grace on the white marble floor left me speechless as we danced, our wings unfurling to wrap around one another like long-lost lovers. I saw a fire then in her brilliant blue eyes that I suspect I shall never be able to forget. How could I ever forget her? Tears began to fall from my cheeks, and she asked why I was crying. Oh, my sweet Drishti. Never leave me behind again.
