Silver Sword Of The Astral Plane BG3 And How To Obtain The Weapon

The Silver Sword of the Astral Plane stands as one of the most formidable legendary weapons available in Baldur's Gate 3. Tailored specifically for Githyanki characters like Lae'zel, this legendary greatsword provides exceptional bonuses that drastically enhance offensive and defensive capabilities. Understanding how to acquire this powerful blade will significantly bolster your party's combat efficiency throughout the game.

Overview of the Silver Sword of the Astral Plane

This legendary greatsword delivers massive psychic damage alongside its base slashing power. When wielded by a Githyanki character, it unlocks passive perks such as advantage on Intelligence, Wisdom, and Charisma saving throws. Additionally, it grants resistance to psychic damage and immunity to the charmed condition, making the wielder a resilient frontline fighter.

The weapon also features unique combat actions like Soulbreaker, which deals additional psychic damage and can stun target enemies. These properties make it an ideal end-game weapon for martial builds looking to maximize damage output. Equipping Lae'zel or a Githyanki custom main character with this sword turns tough encounters into manageable victories.

Obtaining the Sword Early in Act 1

While intended for Act 3, clever players can acquire the Silver Sword during Act 1 at the Mountain Pass encounter. Kith'rak Voss carries the weapon while riding his red dragon near the Rosymorn Monastery Trail. By utilizing stealth and specific spells, players can force Voss to drop his weapon before he flies away.

To execute this strategy, bring a character capable of casting the Command spell or using the Heat Metal spell from a distance. Positioning a stealthy character using invisibility allows you to cast Command Drop on Voss with a chance of success. If successful, Voss drops the blade onto the ground, allowing you to snatch it up and retreat from combat.

Acquiring the Weapon Naturally in Act 3

If you miss the early exploit, you can acquire the blade through the intended narrative path during Act 3. Progressing Lae'zel's companion quest line leads to crucial interactions with Kith'rak Voss regarding the fate of Prince Orpheus. Accepting Voss's quest to free Orpheus or presenting the Orphic Hammer earns his full trust.

Upon meeting Voss in the Sharess' Caress taproom or sewer hideout, completing his dialog triggers him to reward you directly. He hands over the Silver Sword of the Astral Plane as a symbol of your alliance against Vlaakith. This method ensures you gain the weapon without relying on high-risk spells or save-reloading tricks.

Maximizing Combat Potential with the Greatsword

To fully capitalize on the blade's strengths, pair it with heavy armor builds and feats like Great Weapon Master. The passive saving throw advantages allow your warrior to withstand disabling spells cast by mind flayers and rival spellcasters. This defensive layer ensures your primary damage dealer remains active during critical turns.

Combining the sword's innate psychic damage with additional elemental buffs creates devastating melee attack combinations. Whether obtained through tactical cunning in Act 1 or earned honorably in Act 3, this weapon remains a premier choice for any adventuring party.
