Unveiling the Silent Executioner: A Unique Pure Assassin Rogue Build for Baldur's Gate 3

Welcome, adventurer! You seek a path less traveled, a pure Rogue build that dances in the shadows, striking with lethal precision when enemies least expect it. This guide details the "Silent Executioner," a Human Assassin who specializes in dual-wielding melee combat, turning the tide of battle before it truly begins. Forget common multiclass concoctions or the typical Thief acrobatics; this build focuses on the raw, unadulterated power of the Assassin's surprise mechanics, delivering catastrophic damage in the opening moments of any encounter. Prepare to become the embodiment of a whisper that kills.

Build Highlights: The Edge of the Shadow

First-Round Annihilation: Leverage the Assassin's unique features like Assassinate: Ambush and Assassinate: Initiative to gain automatic critical hits and advantage against unprepared foes, often neutralizing key threats instantly.
Master of Stealth & Surprise: This build excels at initiating combat on your terms. As a Human, your skill versatility complements the Assassin's natural affinity for staying unseen and striking from the darkness.
Pure Class Purity: Experience the full depth of the Rogue class from level 1 to 12 without multiclassing, showcasing the formidable power of a dedicated Assassin. Dual-wielding finesse weapons becomes an art form of deadly, rapid strikes.

Core Gameplay Philosophy: The Decisive Blow

The Silent Executioner operates on a simple yet profoundly effective principle: eliminate threats before they can react. Your primary goal is to achieve the "Surprised" status on enemies by initiating combat from a hidden position. This allows your Assassin features to shine, turning your initial attacks into a devastating volley of critical hits. Beyond the first round, you'll utilize your Cunning Actions to reposition, re-enter stealth if possible, and continue to pick off targets with calculated precision. This is not a build for sustained brawling but for intelligent, tactical engagements where the first strike is often the last.

Strategic Positioning: The Shadow's Embrace

Positioning is paramount for the Silent Executioner. Before combat, survey the battlefield for vantage points, shadowy corners, and escape routes. High ground can be beneficial, but more importantly, seek locations that allow you to approach enemies undetected.

Pre-Combat Setup:

Scouting: Always send your Rogue ahead in stealth to identify enemy placements, patrol patterns, and high-priority targets (like spellcasters or enemy leaders).
Chokepoints & Cover: Utilize narrow passages to funnel enemies or use environmental cover to break line of sight after an attack.
Isolate Targets: If possible, try to lure individual enemies away from their group for a quieter takedown, though the Assassin excels at multi-target burst if surprise is achieved on a group.

During Combat:

Initial Strike: Deliver your opening salvo from stealth, ideally targeting the most dangerous or vulnerable enemy.
Hit and Run: After your initial burst, use your Cunning Action: Disengage to safely move away from melee threats or Cunning Action: Hide to attempt to re-enter stealth.
Flanking: If an ally is engaging an enemy in melee, attacking that enemy grants you Sneak Attack even without Advantage (provided you don't have Disadvantage).

Stealth Strategy: Vanish and Vanquish

Your effectiveness hinges on your mastery of stealth. Invest heavily in the Stealth skill and seek out gear that enhances it. The goal is not just to be unseen, but to manipulate the enemy's awareness to your advantage.

Maximizing Stealth Skill: Expertise in Stealth is a must. Aim for the highest possible Stealth score through Dexterity and proficiency.
Environmental Awareness: Use dim light and darkness to your advantage. Be mindful of enemy sight cones (press Shift by default to see them).
Distractions: While not a primary focus, minor illusions (from spells or items if available to the party) or throwing objects can sometimes divert attention, creating openings for you to move or strike.
Achieving Surprise: To make enemies Surprised, your entire party should ideally be hidden or out of their detection range when you initiate combat with an attack from stealth. This is crucial for triggering Assassinate: Ambush.

Leveling Progression: The Path of the Assassin (Human)

As a Human, you benefit from +1 to all ability scores, an additional skill proficiency, and increased carrying capacity. This guide assumes the standard Baldur's Gate 3 Human. We'll prioritize Dexterity for attack, damage, AC, and skills, followed by Constitution for survivability.

Initial Ability Scores (Example using Standard Array: 15, 14, 13, 12, 10, 8 before Human bonuses):

Strength: 8 + 1 = 9
Dexterity: 15 + 1 = 16
Constitution: 14 + 1 = 15
Intelligence: 12 + 1 = 13
Wisdom: 10 + 1 = 11
Charisma: 13 + 1 = 14

Level by Level:

Level 1: Rogue
- Skills: Choose Stealth, Sleight of Hand, Acrobatics, Perception. (Human grants one extra proficiency, choose one like Persuasion or Deception).
- Expertise: Select Stealth and Perception. These are vital for scouting, avoiding traps, and setting up ambushes.
- Sneak Attack: 1d6.
Level 2: Rogue
- Cunning Action: Hide, Dash, Disengage. This is your bread and butter for mobility and re-stealthing.
Level 3: Rogue - Assassin Subclass
- Assassin's Alacrity: At the start of combat, your Action and Bonus Action are restored. This ensures you're always ready for your first turn.
- Assassinate: Initiative: You have Advantage on Attack Rolls against creatures that haven't taken a turn yet in combat.
- Assassinate: Ambush: Any successful Attack Roll against a Surprised creature is a Critical Hit. This is the cornerstone of your burst damage.
- Sneak Attack: 2d6.
Level 4: Rogue - Feat
- Feat: Ability Score Improvement (ASI). Increase Dexterity by +2 (Dexterity becomes 18). This boosts your attack rolls, damage, AC, initiative, and Dexterity-based skills.
Level 5: Rogue
- Uncanny Dodge: Use your reaction to halve the damage of an attack you can see. A crucial defensive tool.
- Sneak Attack: 3d6.
Level 6: Rogue
- Expertise: Select Sleight of Hand and Acrobatics (or another preferred skill if Acrobatics isn't as high priority for your playstyle).
Level 7: Rogue
- Evasion: When subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail. Excellent against area-of-effect spells and traps.
- Sneak Attack: 4d6.
Level 8: Rogue - Feat
- Feat: Dual Wielder. This feat grants you a +1 bonus to Armour Class while you are wielding a separate melee weapon in each hand. You can also engage in two-weapon fighting even when the one-handed melee weapons you are wielding aren't Light (e.g., Rapiers in both hands).
Level 9: Rogue
- Infiltration Expertise: You can mimic the speech and behavior of any creature you've heard or seen, gaining Advantage on Deception and Performance Checks when trying to pass yourself off as that creature. More situational for combat but offers unique roleplaying and utility options.
- Sneak Attack: 5d6.
Level 10: Rogue - Feat
- Feat: Ability Score Improvement (ASI). Increase Dexterity by +2 (Dexterity becomes 20). Maxing out your primary stat.
Level 11: Rogue
- Reliable Talent: Whenever you make an ability check with a skill you are Proficient in, the lowest you can roll on the d20 is a 10. This makes your key skills incredibly consistent.
- Sneak Attack: 6d6.
Level 12: Rogue - Feat
- Feat: Savage Attacker. When you make a melee weapon attack, you roll your damage dice twice and use the highest result. This significantly boosts your damage output, especially with critical hits from Assassinate: Ambush.

Patch 8 Adjustments & Combat Considerations

As of Patch 8 and subsequent updates, the core mechanics for Rogues and Assassins remain largely consistent. Sneak Attack is usable once per turn, meaning you can apply its bonus damage to either your main-hand or off-hand attack, provided the conditions (Advantage or an ally threatening the target within 1.5m, and you don't have Disadvantage) are met. The Assassin's strength in guaranteeing critical hits on surprised targets makes this "once per turn" Sneak Attack incredibly potent in the opening round.

The key to this build's power under current game versions is the reliable application of the "Surprised" condition. This requires careful planning and often party coordination. If surprise cannot be achieved, Assassinate: Initiative still grants Advantage against enemies who haven't acted, which is a significant boon for landing your Sneak Attack.

Combat Synergies

Party Members with Crowd Control: Spells like Hold Person, Hypnotic Pattern, Web, or abilities that can make enemies Prone or Blinded create fantastic opportunities for Sneak Attacks and regular Advantage.
Characters who can help achieve Surprise: Casters with Invisibility or Greater Invisibility, or characters with high group Stealth.
Buffers: Spells like Haste (from an ally or potion) can grant an extra Action, potentially allowing more attacks in a turn, though Sneak Attack remains once per turn. Bless improves attack rolls.
Tanks/Frontliners: Allies who can draw enemy attention allow you to maneuver more freely and pick your targets.

Sneak Attack Optimization

Maximizing your Sneak Attack is crucial:

Surprise Round: This is your golden opportunity. Assassinate: Ambush makes your hits critical, and Assassinate: Initiative gives Advantage. Sneak Attack on a critical hit is devastating.
Attacking from Hidden: Successfully using Cunning Action: Hide grants Advantage on your next attack.
Ally Engagement: If an ally is within 1.5m of your target and isn't incapacitated, and you don't have Disadvantage, you can Sneak Attack.
Exploiting Conditions: Attack enemies who are Prone, Blinded, Paralyzed, Restrained, etc., to gain Advantage.

Build Strengths and Weaknesses

Strengths

Exceptional First-Round Burst Damage: Capable of neutralizing high-priority targets before they can act, especially with successful Surprise.
Excellent Scout and Initiator: High Stealth and Perception make you ideal for reconnaissance and choosing when and where combat begins.
High Mobility: Cunning Actions allow for unparalleled battlefield repositioning and hit-and-run tactics.
Strong Single-Target Elimination: Focuses on taking down individual enemies quickly and efficiently.
Good Skill Utility: Expertise in key skills like Stealth, Perception, and Sleight of Hand provides significant out-of-combat utility.
Unique and Engaging Playstyle: Offers a different rhythm to Rogue gameplay compared to the more common Thief builds, emphasizing tactical assassinations.

Weaknesses

Reliant on Surprise/Advantage: Damage output significantly drops after the first round if you cannot consistently gain Advantage or re-enter stealth.
Lower Sustained Damage Compared to Some Builds: If long, drawn-out fights occur without opportunities for Sneak Attack, your damage may not keep pace with more combat-focused martial classes or Thief Rogues with extra bonus action attacks.
Relatively Squishy: Relies on Light Armour, high Dexterity, Uncanny Dodge, and Evasion for defense. Can be vulnerable if caught out of position or focused by multiple enemies.
Vulnerable to Anti-Stealth Measures: Enemies with high Perception, True Sight, or area-of-effect abilities that reveal hidden creatures can disrupt your strategy.
Limited Area-of-Effect Damage: Primarily a single-target specialist. Dealing with large groups of weaker enemies can be challenging without party support.
Execution Dependent: Requires careful planning, positioning, and understanding of stealth mechanics to be truly effective.
