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

This guide delves into crafting a potent Gloomstalker Assassin multiclass character in Baldur's Gate 3, leveraging the strengths of both Ranger and Rogue subclasses for devastating physical damage and unmatched versatility.

This lethal combination excels in both melee and ranged combat, capitalizing on shared skills in stealth, lockpicking, and trap disarming. The Ranger contributes weapon proficiencies and supportive spells, while the Rogue adds devastating melee capabilities. Their combined stealth prowess is truly formidable.

Note: While Larian Studios has confirmed no DLC or sequels for BG3, Patch 8 (anticipated in 2025) will introduce new subclasses, opening up further build possibilities.

The Gloomstalker Assassin Build: Savage Stealth in Any Environment

This build fuses the dedicated hunter (Gloomstalker) with the vicious killer (Assassin) into a hardened mercenary and survivalist. The effectiveness of this build in both close-quarters and long-range combat depends heavily on skill, ability, and gear choices. Shared proficiencies in Stealth, Sleight of Hand, and Dexterity make this multiclass a natural fit. The inclusion of Ranger spells (and potentially racial cantrips) adds a layer of tactical depth.

Ability Scores: Dexterity, Wisdom, and More

Prioritize physical damage and resilience over heavy spellcasting, but don't neglect spells entirely.

  • 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 class.
  • Strength: Less critical, depending on the chosen melee DPS focus.
  • Intelligence: The "dump stat," largely irrelevant to both Ranger and Rogue abilities.
  • Charisma: Less important, though creative players can find uses for it.
