Lore
Omar: This place reeks of death. Toland: Worse. Rebirth. Sai: Once something is gone, it should stay that way. Eriana-3: I can't share that sentiment. Sai: You will never find peace if you can't accept your loss. Eriana-3: I'll find peace when I rip that monster's beating heart from his chest. Eris: I have never known vengeance to bring peace. Eriana-3: What do you think I should hope for, then? All I have left is my vengeance and my gun. Eris: A Hand Cannon with a sight, yet you see nothing but rage. Don't allow it to cloud your judgement. Wei gave you the weapon for a purpose. Eriana-3: Yeah, to keep me at a distance from the Hive. And now I'm heading straight toward them. Somewhere out there, she's shaking a fist at me. Eris: We can honor her still by ridding the world of the disease that is Crota. Eriana-3: There is no world for me after Crota. Eris: What you are feeling… is to be expected. In time, we can forge a new world. Together. Eriana-3: I want to believe that is possible. Vell: I hate to interrupt this touching moment, but does anyone else hear that? Sai: That rumble? Toland: Thralls… I think they mean to welcome us. Eriana-3: Let them come. I'll be the last Light they ever see.

Gameplay

 * Eriana's Vow does not play much like the average hand cannon. Instead, it functions much like a handheld sniper. This is due to the small cylinder size, low ammo reserves, long reload time, high range, low fire rate, high impact, and perks that incentivize landing precision hits.
 * It even has a proper scope, unlike most hand cannons.
 * In order to maximize your damage while using this weapon, it is imperative that you land precision hits or hit enemies with elemental shields.
 * While most other hand cannons are great for clearing weak enemies with a single precision hit, it is inadvisable to use Eriana's Vow like this. Instead, save your ammo for stronger enemies.
 * Eriana's Vow has innate barrier-piercing rounds, making it useful in weeks of Nightfall: The Ordeal that have barrier champions. Notably, however, these barriers are not considered elemental shields for the purposes of the Death at First Glance perk, but the effect can be extended to the next shot by landing precision hits through the shield.
 * You do not have to worry about landing precision hits on enemies with elemental shields since it is impossible to do so. However, pay attention to when the barrier is broken; carelessly firing away at enemies with elemental shields may cause players to lose the Death at First Glance buff by accidentally landing body shots after breaking the elemental shield.
 * Players may unscope and preserve the Death at First Glance buff for future shots, then re-position and rescope later to still deal full damage.
 * In the Crucible, players will spawn with 4 rounds instead of 2 as in other special ammo weapons. This is because the damage in PVP is low compared to other special ammo weapons, with two precision hits being required to kill an enemy player from full health and shields.

Trivia

 * Eriana's Vow is the first Hand Cannon in Destiny 2 that uses special ammo.
 * It is named after the Exo Warlock Eriana-3, and her vow of vengeance against Crota for The Battle of Mare Ibrium.
 * Its ornament For Wei could be obtained at rank 100 of the premium track for the Season 8 Season Pass. It is likely named after Eriana's deceased lover, the Titan Wei Ning.
 * Wei Ning was killed at the Battle of Mare Ibrium by Crota's forces. Afterwards, Eriana dedicated herself to a quest of vengeance against Crota. Tragically, she died in the failed Raid on the Hellmouth as a member of Eris Morn's fireteam.
 * The ornament modifies the appearance of the gun to a scorched black with a glowing hot muzzle that generates fire particle effects. This may be a reference to the common metaphorical phrases “burning hatred” and/or “burning passion,” both of which apply to Eriana-3.
 * Wei was also the one who gifted the hand cannon to Eriana.
 * With an RPM of 90, an impact of 100, and range of 100, Eriana's Vow is the slowest-firing, hardest-hitting, and longest-ranged hand cannon currently available in Destiny 2.
 * There is no 3D preview of Eriana's Vow available in the Destiny 2 companion app.
 * The muzzle of the weapon bears the symbol of the Cassoid Weapon Foundry.
 * During development, Eriana's Vow set the user on fire when fired, a feature later mirrored by Tommy's Matchbook.
 * Eriana's Vow and Eriana's Vengeance were both owned by the Exo Warlock Eriana-3
