How do I build a high-damage Warlock in Baldur's Gate 3?

Building a high-damage Warlock in Baldur's Gate 3 requires a deep understanding of the class mechanics, ability scores, spell selection, and combat tactics. Warlocks are unique in that they rely heavily on their Eldritch Blast cantrip, which scales with level and can be enhanced through invocations. HereÔÇÖs a detailed guide to creating a Warlock that deals significant damage while remaining versatile and effective in various situations.

First, letÔÇÖs discuss the core mechanics of the Warlock class. Warlocks are Charisma-based spellcasters, meaning Charisma is their primary ability score. This affects their spellcasting, including the attack rolls and saving throw DCs of their spells. Constitution is also important for maintaining concentration on spells and surviving in combat. Dexterity can be useful for improving Armor Class (AC) and initiative, but itÔÇÖs secondary to Charisma and Constitution.

When creating your Warlock, prioritize Charisma as your highest stat, aiming for at least 16 or 17 at level 1. Constitution should be your second-highest stat, ideally around 14 or 15. Dexterity can be set to 14 for a decent AC if youÔÇÖre not wearing heavy armor. Strength, Intelligence, and Wisdom can be lower, as they are less critical for a WarlockÔÇÖs primary role.

For race selection, consider options that complement your Charisma and provide useful abilities. Tieflings, Half-Elves, and Drow are excellent choices. Tieflings gain a Charisma bonus and access to racial spells like Hellish Rebuke, which can add to your damage output. Half-Elves receive a +2 Charisma bonus and two additional +1 bonuses to other stats, making them versatile. Drow gain Darkvision and Faerie Fire, which can help in combat by revealing hidden enemies.

At level 1, choose the Fiend or Great Old One as your patron. The Fiend patron is ideal for a high-damage build because it grants temporary hit points when you reduce an enemy to 0 HP, increasing your survivability. The Great Old One offers more utility with features like Awakened Mind, but itÔÇÖs less focused on direct damage. For your starting cantrip, Eldritch Blast is a must. ItÔÇÖs your primary damage-dealing tool and scales with your level, making it consistently powerful.

At level 2, youÔÇÖll gain access to invocations. Agonizing Blast is essential, as it adds your Charisma modifier to Eldritch BlastÔÇÖs damage. This significantly boosts your damage output. Another useful invocation is Repelling Blast, which pushes enemies away when you hit them with Eldritch Blast. This can be used to control the battlefield, keeping enemies at a distance or knocking them into environmental hazards.

For spell selection, focus on spells that complement your damage-dealing role. Hex is a fantastic choice, as it adds extra necrotic damage to your attacks and imposes disadvantage on ability checks for the target. This synergizes well with Eldritch Blast. Other useful spells include Armor of Agathys for temporary hit points and retaliation damage, and Misty Step for mobility. As you level up, consider spells like Fireball (if youÔÇÖre a Fiend Warlock) or Hunger of Hadar for area control and damage.

At level 3, youÔÇÖll choose your Pact Boon. Pact of the Tome is a solid choice for versatility, granting additional cantrips and ritual spells. Pact of the Chain offers a familiar that can provide utility and support in combat. Pact of the Blade is less optimal for a pure Warlock build focused on spellcasting, but it can be useful if you plan to multiclass into a martial class later.

As you progress, continue to prioritize Charisma increases at levels 4, 8, and 12. This will maximize your spellcasting effectiveness and Eldritch Blast damage. Feats like War Caster can be useful for maintaining concentration on spells, while Spell Sniper can increase your spell attack range and ignore cover.

In combat, your primary strategy is to stay at range and spam Eldritch Blast. Use Hex early in the fight to maximize its damage over time. Position yourself carefully to avoid being targeted by melee enemies, and use Repelling Blast to keep threats at bay. If enemies close in, Misty Step can help you reposition quickly.

Common mistakes to avoid include neglecting Charisma, which directly impacts your damage output, and overcommitting to melee combat. Warlocks are not designed to be frontline fighters, so staying at range is crucial. Additionally, avoid spreading your ability scores too thin. Focus on Charisma and Constitution, and let your spells and invocations handle the rest.

Advanced techniques include multiclassing for additional versatility. For example, a two-level dip into Sorcerer can grant access to Metamagic, allowing you to quicken Eldritch Blast for double the damage in a single turn. Alternatively, a Paladin multiclass can create a powerful melee Warlock with access to smites and heavy armor.

In summary, building a high-damage Warlock in Baldur's Gate 3 involves maximizing Charisma, selecting the right invocations and spells, and using Eldritch Blast as your primary damage tool. Stay at range, control the battlefield, and avoid common pitfalls like neglecting your primary stats or overcommitting to melee combat. With careful planning and execution, your Warlock can become a devastating force on the battlefield.
