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 scenarios.

First, letÔÇÖs discuss the core mechanics of the Warlock class. Warlocks are Charisma-based spellcasters, meaning your primary ability score should be Charisma. This affects your spell attack rolls, spell save DC, and the effectiveness of your Eldritch Blast. At level 1, youÔÇÖll want to prioritize Charisma, followed by Constitution for survivability and Dexterity for AC and initiative. A typical starting spread might be 16 Charisma, 14 Constitution, and 14 Dexterity, with the remaining points distributed as needed.

When choosing your race, consider options that boost Charisma or provide useful racial abilities. Tieflings, Half-Elves, and Drow are excellent choices due to their Charisma bonuses and additional spells or resistances. For example, a Half-Elf can start with 17 Charisma, allowing you to reach 18 with the right ability score improvement later.

At level 1, youÔÇÖll select your Patron, which defines your WarlockÔÇÖs flavor and grants unique abilities. The Fiend is a strong choice for a damage-focused build, as it provides temporary hit points when you reduce an enemy to 0 HP, enhancing your survivability. The Great Old One and Archfey are also viable, offering different utility and control options.

Your spell selection is crucial. Eldritch Blast is your bread-and-butter damage spell, and youÔÇÖll want to take the Agonizing Blast invocation as soon as possible. This adds your Charisma modifier to the damage of each Eldritch Blast beam, significantly increasing your damage output. At level 2, you gain access to invocations, and Agonizing Blast should be your first pick. Other useful invocations include Repelling Blast, which pushes enemies away, and DevilÔÇÖs Sight, which allows you to see in magical darkness.

For spells, focus on those that complement your damage-dealing role. Hex is a must-have, as it adds 1d6 necrotic damage to each hit against the cursed target. This synergizes well with Eldritch Blast, especially at higher levels when you can fire multiple beams. Other useful spells include Armor of Agathys for temporary hit points and retaliation damage, and Misty Step for mobility.

As you level up, prioritize increasing your Charisma to 20 as soon as possible. This maximizes your spell attack bonus, spell save DC, and the damage from Agonizing Blast. At level 4, consider taking the Ability Score Improvement to boost Charisma. Alternatively, feats like War Caster can be useful for maintaining concentration on spells like Hex.

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 melee enemies, and use Repelling Blast to keep threats at bay. If youÔÇÖre facing multiple enemies, consider using area-of-effect spells like Hunger of Hadar or Fireball (if youÔÇÖve taken the Fiend patron) to control the battlefield.

Common mistakes to avoid include neglecting your Constitution, which can make you too squishy, and spreading your ability scores too thin. Focus on Charisma first, then Constitution and Dexterity. Also, donÔÇÖt overlook the importance of invocations. They are a core part of your damage output and utility, so choose them wisely.

Advanced techniques involve multiclassing for additional versatility. For example, a two-level dip into Sorcerer can grant you access to Metamagic, allowing you to quicken Eldritch Blast for even more damage in a single turn. Alternatively, a Paladin multiclass can provide smite spells and melee capabilities, though this requires a different ability score distribution.

In terms of D&D 5E rules, Warlocks are unique in that they regain all their spell slots on a short rest, making them highly sustainable in long adventuring days. This mechanic allows you to use your spells more liberally, knowing you can recover them quickly.

Specific examples of high-damage scenarios include using Hex and Eldritch Blast on a single target, dealing 1d10+1d6+Charisma modifier per beam. At level 5, this becomes two beams, effectively doubling your damage output. Against groups, combining Eldritch Blast with area spells like Hunger of Hadar can control the battlefield while dealing consistent damage.

In summary, building a high-damage Warlock in Baldur's Gate 3 involves maximizing your Charisma, selecting the right invocations and spells, and positioning yourself effectively in combat. By focusing on Eldritch Blast and Hex, and enhancing your abilities through invocations and careful spell selection, you can create a Warlock that deals significant damage while remaining versatile and resilient.
