Summary

The Gloomstalker Assassin build excels in delivering high physical damage and offers versatility in combat scenarios.
Dexterity is crucial for both Rangers and Rogues, while Wisdom enhances the Ranger's spellcasting abilities.
Choose racial abilities, backgrounds, and gear that enhance Dexterity, Wisdom, or Constitution to optimize your build.

Multiclassing in Baldur's Gate 3 allows players to craft unique and customized characters, and the Ranger and Rogue combination is particularly popular. This build becomes even more formidable when integrating the Gloomstalker and Assassin subclasses into one deadly package.

Both classes rely heavily on Dexterity for their primary abilities, excelling in Stealth, lockpicking, and trap-disarming, which makes them versatile for various party roles. Rangers bring additional weapon skills and support spells to the table, while Rogues offer devastating melee capabilities. Together, their Stealth abilities are unparalleled.

Updated on December 24, 2024, by Kristy Ambrose: Larian Studios has confirmed no DLCs or sequels are planned for BG3, but Patch 8, set to release in 2025, will introduce several new subclasses. This update opens up new possibilities for players experimenting with creative and potentially powerful character builds. For the Ranger and Rogue, Dexterity remains the key ability score, but don't overlook Wisdom for the Ranger's spellcasting prowess. Additionally, consider choices like Backgrounds, Feats, weapons, and Gear to fine-tune your character.

The Gloomstalker Assassin Build

Savage & Stealthy Damage In Any Environment

A blend of dedicated hunter and ruthless killer, crafting a lethal survivalist and hardened mercenary.

The Gloomstalker Assassin is designed for delivering high physical damage, effective in both melee and ranged combat. The effectiveness at close or long range depends on the specific build, including chosen skills, abilities, and gear.

Rogues and Rangers share key attributes such as Stealth, Sleight of Hand, and proficiency in Dexterity, making them a natural fit for a multiclass build. Rangers can also incorporate some support spells and, depending on racial choices, may have access to Cantrips, allowing for limited spellcasting abilities within this build.

Ability Scores

Dexterity For Rogues, Wisdom For Rangers

Prioritize physical damage and resilience while maintaining some spellcasting capabilities.

Both classes rely on Dexterity as their most crucial statistic, which also serves as the spellcasting modifier for Rogues. For Rangers, however, Wisdom is used for spellcasting.

Dexterity: Essential for Sleight of Hand, Stealth, and weapon proficiency for both classes.
Wisdom: Vital for Perception checks and effective casting of support spells like healing or removing curses.
Constitution: A higher Constitution increases hit points, which is crucial for this combat-focused build.
Strength: Less important but can be beneficial if the build leans towards melee damage.
Intelligence: Often considered a "dump stat" for this build, as neither class heavily relies on arcane casting.
Charisma: Not a priority for this build, though creative players might find ways to leverage it.
