Where can I find the legendary weapon called the Silver Sword of the Astral Plane in Baldur's Gate 3?

The Silver Sword of the Astral Plane is one of the most sought-after legendary weapons in Baldur's Gate 3, and obtaining it requires careful planning, exploration, and combat prowess. This weapon is tied to the Githyanki storyline and is particularly significant for characters who align with or oppose the Githyanki. HereÔÇÖs a detailed guide on how to find and acquire this powerful weapon.

To begin, the Silver Sword of the Astral Plane is wielded by Kith'rak Voss, a high-ranking Githyanki warrior. You first encounter Voss during Act 1, but obtaining the sword requires progressing through the story and making specific choices. The sword is not something you can simply loot from Voss early on, as he is a formidable opponent and story-critical character. Instead, you must wait until Act 3, where the opportunity to acquire the sword becomes available.

In Act 3, you will find yourself in the city of Baldur's Gate. Here, you will encounter Voss again, and this is where the real opportunity to obtain the sword arises. Voss will be located in the Lower City, near the entrance to the Undercity. He will be engaged in a confrontation with other Githyanki, and this is your chance to intervene. Depending on your choices and dialogue options, you can either ally with Voss or oppose him. If you choose to ally with him, you can negotiate for the sword, but this requires high Persuasion or Intimidation checks. If you fail these checks, or if you choose to oppose him, you will need to defeat him in combat to claim the sword.

Combat with Voss is no small feat. He is a high-level Githyanki warrior with powerful abilities, including multi-attack, teleportation, and resistance to certain types of damage. To prepare for this fight, ensure your party is well-equipped with high-level gear and spells. Characters with high AC and strong melee capabilities, such as Fighters or Paladins, are particularly useful. Additionally, having a Cleric or Druid for healing and support can make a significant difference. Spells like Hold Person or Banishment can temporarily neutralize Voss, giving you a strategic advantage.

One common mistake players make is underestimating Voss's combat abilities. He can quickly overwhelm an unprepared party, so itÔÇÖs crucial to approach the fight with a solid strategy. Focus on controlling the battlefield by using area-of-effect spells and abilities to limit his mobility. Additionally, make sure to target any other Githyanki allies he may have, as they can provide significant support to him.

Advanced techniques for this encounter include using environmental hazards to your advantage. If the fight takes place near ledges or chasms, spells like Thunderwave or Eldritch Blast with the Repelling Blast invocation can push Voss or his allies off the edge, instantly removing them from the fight. Additionally, using invisibility or stealth to position your party before initiating combat can give you a tactical edge.

From a D&D rules perspective, the Silver Sword of the Astral Plane is a +3 greatsword with additional properties. It deals extra psychic damage to creatures native to the Material Plane, making it particularly effective against many enemies in the game. It also grants the wielder advantage on saving throws against being charmed or frightened, which can be invaluable in certain encounters.

In terms of character building, this weapon is ideal for martial classes like Fighters, Paladins, and Barbarians. Its high damage output and additional properties make it a top-tier choice for any melee-focused character. If youÔÇÖre playing a Githyanki character, the sword has additional narrative significance, as it ties into the GithyankiÔÇÖs lore and their ongoing conflict with the Mind Flayers.

In summary, obtaining the Silver Sword of the Astral Plane in Baldur's Gate 3 requires careful progression through the story, strategic combat preparation, and making key dialogue choices. By following this guide, you can ensure that your party is ready to face Kith'rak Voss and claim this legendary weapon for your own. Whether you choose to negotiate or fight, the Silver Sword of the Astral Plane is a powerful addition to any adventurerÔÇÖs arsenal.
