Mastering the Gloomstalker Assassin in Baldur's Gate 3: A Comprehensive Guide

This guide details a powerful multiclass build combining the Ranger's Gloomstalker and the Rogue's Assassin subclasses in Baldur's Gate 3. This lethal combination excels in both melee and ranged combat, leveraging stealth and devastating damage.

This build thrives on the synergy between Ranger and Rogue abilities, particularly their shared focus on Dexterity for core skills like Stealth and Sleight of Hand. Rangers contribute weapon proficiencies and support spells, while Rogues offer potent melee capabilities. Their combined stealth prowess is unmatched.

Updated December 24, 2024: While Larian Studios has confirmed no BG3 DLC or sequels, Patch 8 (2025) introduces new subclasses, opening exciting build possibilities. For this Ranger/Rogue build, Dexterity remains paramount, complemented by Wisdom for spellcasting and careful consideration of Background, Feats, weapons, and Gear.

The Gloomstalker Assassin: Savage Stealth in Any Terrain

This build seamlessly blends the deadly precision of an assassin with the survival skills of a seasoned hunter. Damage output is exceptional, whether engaging at close range or from afar. The player's skill choices, abilities, and gear will determine the preferred combat style (melee or ranged).

The natural overlap between Rogues and Rangers—Stealth, Sleight of Hand, Dexterity proficiency—makes this multiclassing a highly effective strategy. Access to Ranger support spells and potential Cantrips (depending on race selection) adds further versatility.

Ability Scores: Dexterity and Wisdom Dominate

Prioritize physical damage and resilience over extensive spellcasting, though some spellcasting remains viable.

  • Dexterity: Crucial for Sleight of Hand, Stealth, and weapon proficiency for both classes.
  • Wisdom: Essential for Ranger spellcasting and Perception checks.
  • Constitution: Increases hit points—a medium priority for this combat-focused build.
  • Strength: Less important, unless prioritizing melee DPS.
  • Intelligence: A "dump stat" with limited use for either class.
  • Charisma: Relatively unimportant, although creatively utilized in specific scenarios.
