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 choices, and combat strategies. 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 both their spellcasting and their Eldritch Blast damage. At level 1, Warlocks gain access to Eldritch Blast, a cantrip that fires a beam of energy at a target. This cantrip scales with character level, not Warlock level, meaning it becomes more powerful as you gain levels, regardless of multiclassing. At level 1, it fires one beam, at level 5 it fires two beams, at level 11 it fires three beams, and at level 17 it fires four beams. Each beam requires a separate attack roll and deals 1d10 force damage, making it one of the most reliable damage-dealing cantrips in the game.

To maximize your WarlockÔÇÖs damage output, you should prioritize Charisma. Start with a Charisma score of 17, which can be achieved by selecting a race that provides a Charisma bonus, such as Tiefling or Half-Elf. Use your ability score improvements at levels 4 and 8 to increase Charisma to 20. This will boost your spell attack modifier, spell save DC, and Eldritch Blast damage.

Next, choose the right invocations. Invocations are special abilities that Warlocks gain at certain levels, and they can significantly enhance your damage output. The most important invocation for a high-damage Warlock is Agonizing Blast, which allows you to add your Charisma modifier to the damage of each Eldritch Blast beam. This means that at level 5, with a Charisma of 20, each beam will deal 1d10 + 5 damage, and youÔÇÖll be firing two beams per turn. Another useful invocation is Repelling Blast, which pushes enemies back 10 feet with each beam, providing both damage and battlefield control.

For your Pact Boon at level 3, the Pact of the Tome is a solid choice for versatility, as it grants you additional cantrips from any class. However, if you want to focus purely on damage, the Pact of the Blade allows you to summon a magical weapon and use your Charisma modifier for attack and damage rolls, making you effective in melee combat as well. This can be useful if you find yourself in close-quarters combat, though Eldritch Blast will still be your primary damage source.

When it comes to spell selection, Warlocks have limited spell slots, but they recharge on a short rest, making them highly efficient in prolonged encounters. Focus on spells that enhance your damage or provide utility. Hex is a must-have spell, as it adds 1d6 necrotic damage to each attack you make against the cursed target. Since Eldritch Blast fires multiple beams, Hex can significantly increase your damage output. Other useful spells include Armor of Agathys for temporary hit points and retaliation damage, and Misty Step for mobility.

In combat, your primary strategy should be to position yourself at a safe distance and spam Eldritch Blast. Use Hex on your primary target to maximize damage, and take advantage of Repelling Blast to keep enemies at bay. If youÔÇÖre facing multiple enemies, consider using area-of-effect spells like Hunger of Hadar or Fireball (if youÔÇÖve multiclassed or taken the Fiend patron) to deal damage to groups.

One common mistake to avoid is neglecting your defenses. While Warlocks are powerful damage dealers, they are relatively squishy. Make sure to invest in some defensive spells or abilities, such as Armor of Agathys or the Fiend patronÔÇÖs Dark OneÔÇÖs Blessing, which grants temporary hit points when you reduce an enemy to 0 hit points. Additionally, consider taking the Moderately Armored feat if youÔÇÖre not already proficient in medium armor, as this will significantly increase your survivability.

For advanced optimization, consider multiclassing. A popular choice is to take two levels of Fighter for Action Surge, which allows you to cast Eldritch Blast twice in one turn, effectively doubling your damage output for that round. Another option is to take a few levels in Sorcerer for Metamagic, which can be used to quicken Eldritch Blast, allowing you to cast it as a bonus action.

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. Focus on Eldritch Blast as your primary damage source, enhance it with Agonizing Blast and Hex, and use your spell slots wisely. Avoid common mistakes like neglecting defenses, and consider multiclassing for additional versatility and power. With these strategies, your Warlock will be a formidable force on the battlefield, capable of dealing massive damage while maintaining flexibility and survivability.
