What is the best multiclass combination for a Monk in Baldur's Gate 3?

The Monk class in Baldur's Gate 3 is a highly versatile and mobile martial class that excels in unarmed combat, agility, and ki-based abilities. Multiclassing a Monk can enhance their strengths or compensate for their weaknesses, depending on your playstyle. One of the best multiclass combinations for a Monk is with the Rogue class, specifically the Thief subclass. This combination leverages the Monk's speed and unarmed strikes with the Rogue's sneak attack and additional bonus actions, creating a highly effective and dynamic character.

To start, let's break down the mechanics involved. Monks rely on Dexterity and Wisdom for their AC, attack rolls, and saving throws. Their Ki points allow them to perform special abilities like Flurry of Blows, Patient Defense, and Step of the Wind. Rogues, on the other hand, gain Sneak Attack, which deals extra damage when attacking with advantage or when an ally is adjacent to the target. The Thief subclass grants an additional bonus action, which synergizes perfectly with the Monk's ability to make multiple attacks in a single turn.

To build a Monk/Rogue multiclass, you should start as a Monk for the first six levels. This ensures you gain Extra Attack at level 5, which is crucial for maximizing your damage output. At Monk level 6, you also gain Ki-Empowered Strikes, allowing your unarmed attacks to count as magical for overcoming resistance. After reaching Monk 6, you can begin taking levels in Rogue. Aim for at least three levels in Rogue to unlock the Thief subclass, which grants you an additional bonus action. This extra bonus action can be used for another Flurry of Blows, effectively doubling your potential damage output in a single turn.

When allocating ability scores, prioritize Dexterity for attack rolls, AC, and initiative. Wisdom is also important for your Monk abilities and AC. Constitution should be your third priority to increase your survivability. Intelligence, Charisma, and Strength can be left at lower values unless you have a specific roleplay or story reason to invest in them.

In combat, the Monk/Rogue multiclass excels at hit-and-run tactics. Use your high mobility to position yourself advantageously, and take advantage of the Rogue's Cunning Action to Dash, Disengage, or Hide as a bonus action. This allows you to stay out of harm's way while dealing consistent damage. The Thief's additional bonus action can be used for a second Flurry of Blows, or to Disengage and retreat after attacking. This makes you incredibly hard to pin down and allows you to control the battlefield effectively.

One common mistake to avoid is neglecting your Wisdom score. While Dexterity is your primary stat, Wisdom is crucial for your Monk abilities and AC. Failing to invest in Wisdom can leave you vulnerable and reduce the effectiveness of your Ki abilities. Another mistake is multiclassing too early. Delaying your Monk progression can hinder your access to key abilities like Extra Attack and Ki-Empowered Strikes. It's generally best to reach Monk level 6 before considering multiclassing.

Advanced techniques for this build include using the Mobile feat to further enhance your mobility and avoid opportunity attacks. This feat allows you to move away from enemies you've attacked without provoking opportunity attacks, making you even more elusive. Additionally, consider using weapons that benefit from both Monk and Rogue abilities, such as shortswords or daggers, which can be used for both Sneak Attack and Monk weapon attacks.

In terms of D&D 5E rules, this multiclass combination is fully supported and balanced. The Monk's Unarmored Defense and Martial Arts abilities work seamlessly with the Rogue's Sneak Attack and Cunning Action. The Thief's additional bonus action is a powerful tool that complements the Monk's need for multiple attacks and mobility.

Specific examples of this build in action include scenarios where you can use your high mobility to flank enemies and trigger Sneak Attack, or where you can use your additional bonus action to perform a second Flurry of Blows to finish off a weakened enemy. In exploration and roleplay, your high Dexterity and Wisdom scores make you adept at stealth, perception, and acrobatics, allowing you to navigate the world with ease and uncover hidden secrets.

In conclusion, the Monk/Rogue multiclass, particularly with the Thief subclass, is a highly effective and versatile build in Baldur's Gate 3. By combining the Monk's martial prowess and mobility with the Rogue's sneak attack and additional bonus actions, you can create a character that excels in both combat and exploration. Careful planning and attention to ability scores, feat selection, and combat tactics will ensure your Monk/Rogue is a formidable force in any situation.
