Baldur's Gate 3 Warlock Patrons: Fiend vs. Great Old One Builds

Baldur's Gate 3 does not have a seasonal system. The latest major update is "Patch 8" (released April 15, 2025), followed by several Hotfixes. Current information

In the world of Baldur's Gate 3, Warlocks forge pacts with otherworldly entities to wield their formidable power. While an enticing class, players face their first major decision at character creation class level 1: choosing a "Patron." Among the most popular, "Fiend" and "Great Old One" Warlocks demand entirely different tactical approaches. Will you support your party with stable combat abilities, or dominate the battlefield with tricky powers? This article thoroughly compares these two subclasses to help you choose the best patron for your playstyle.

Warlock's Basic Abilities

Before choosing a patron, let's review the Warlock class's basic abilities. Warlocks wield powers granted by their pacts, characterized by fewer spell slots that recover on a short rest.

Patron Choice: Fiend vs. Great Old One

Your patron choice dictates your Warlock playstyle. Here, we compare the "Fiend," who burns enemies with demonic power, and the "Great Old One," who erodes enemy minds with cosmic horror. While the cantrip "Eldritch Blast" remains central to combat for both paths, their application and roles differ significantly.

The Demonic Pacts of the Fiend: Balancing Survivability and Damage

The Fiend Warlock makes a pact with entities like Archdevils or powerful devils. Its greatest feature is "Dark One's Blessing," which grants temporary Hit Points (Hit Points (HP)) equal to your Charisma modifier + Warlock class level each time you defeat an enemy. This ability provides incredible staying power in battles with many foes, allowing you to act as both a damage dealer and a sub-tank.

Additionally, the abilities/spells you learn as you gain a class level are very powerful. At class level 3, you learn "Scorching Ray," and at class level 5, "Fireball," a spell synonymous with high-damage area-of-effect abilities. This allows you to contribute to the party with both single-target and area-of-effect damage.

Recommended Playstyle and Builds
The Fiend Warlock is expected to excel as a versatile, self-sufficient attacker. Your basic strategy involves chipping away at enemies from the rear with "Eldritch Blast," and unleashing "Fireball" into dense enemy clusters. The temporary Hit Points (Hit Points (HP)) gained from defeating foes allow you to act without fear of taking some damage. The "Pact of the Blade," chosen at class level 3, which allows you to use your Charisma for melee weapon attacks, also synergizes well, enabling builds focused on frontline combat.

Compatible Races and Feats

• Race: "Zariel Tiefling," with resistance to fire damage, aligns well with the Fiend's theme and has high synergy with learned abilities/spells. "Human" or "Half-Elf," which offer additional armor proficiencies, are also effective choices for bolstering defenses.
• Feat: "War Caster," which makes it easier to maintain concentration abilities/spells, is crucial. "Tough," for increased durability, and "Ability Improvement," to raise your Charisma score, are also classic choices.

Evaluation

• Beginner-Friendly: ★★★★★ (Highly recommended for first-time Warlock players, thanks to its user-friendly abilities and balanced offense/defense.)
• Advanced Player: ★★★☆☆ (While consistently strong, it may lack the burst potential of other subclasses for highly specialized tactics.)

Apostle of the Aberrant: The Great Old One Dominates with Criticals

The Great Old One Warlock makes a pact with unspeakable cosmic entities. The true value of this subclass lies in "Mortal Reminder," an ability learned at class level 1. This powerful feature inflicts the "Frightened" condition on a target and surrounding enemies when you land a critical hit. Since frightened enemies cannot move or take actions, a single critical hit has the potential to turn the tide of battle.

The abilities/spells learned, such as "Dissonant Whispers" and "Tasha's Hideous Laughter," are primarily control-oriented, interfering with enemy minds and hindering their actions. This subclass specializes in neutralizing enemies to gain a combat advantage, rather than focusing on direct damage.

Recommended Playstyle and Builds
Operating a Great Old One Warlock hinges on how effectively you can generate critical hits. Therefore, builds that maximize critical hit chance are prevalent. As your character gains a class level and "Eldritch Blast" begins to fire multiple beams, the increased number of hits provides more opportunities for critical hits, making it perfectly suited for this subclass. By boosting your critical hit chance with equipment and feats, you can continuously fire "Eldritch Blast" to permanently inflict the Frightened condition on enemy groups, dominating the battlefield as a unique crowd controller.

Compatible Races and Feats

• Race: While there's less synergy with specific races, versatile options like "Half-Elf (Shield Proficiency)" and "Human" are always good choices.
• Feat: The highest priority feat is "Spell Sniper," which reduces the die roll needed for a critical hit with spell attacks by 1. The presence or absence of this feat dramatically alters the activation rate of "Mortal Reminder." "War Caster," for maintaining concentration abilities/spells, is recommended as a secondary choice.

Evaluation

• Beginner-Friendly: ★★☆☆☆ (This subclass relies heavily on equipment and feats to boost critical hit chance, so its strength might not be fully realized until the build is complete.)
• Advanced Player: ★★★★★ (Once the build is complete, its battlefield dominance is truly breathtaking. This is the ultimate subclass for players who enjoy unique tactics centered around critical hits.)

Eldritch Blast and Invocations: The Lifeline of All Warlocks

Regardless of which patron you choose, the cantrip "Eldritch Blast" is the fundamental and ultimate ability for Warlock combat. This ability/spell consumes no spell slots, allowing for unlimited use, and automatically strengthens as you gain a class level, firing 2 beams at character level 5 and 3 beams at class level 10, making it a reliable and stable damage source until the endgame.

What truly makes "Eldritch Blast" a powerful ability/spell is the existence of "Eldritch Invocations," which can be learned starting at class level 2. The following Eldritch Invocations, in particular, dramatically enhance a Warlock's combat prowess.

• Agonising Blast: Adds your Charisma modifier to the damage of each beam of "Eldritch Blast." This is such a powerful Eldritch Invocation that it's almost essential for playing a Warlock, significantly boosting damage output.
• Repelling Blast: Pushes enemies hit by "Eldritch Blast" up to 4.5m. This greatly expands tactical options, allowing you to shove enemies off high ground for falling damage or push dangerous foes away from allies.
• Devil's Sight: Allows you to see normally even in magical darkness. Combined with the "Darkness" ability/spell, this creates a powerful combo where you can establish a safe zone to attack enemies unopposed.

How you combine these Eldritch Invocations is key to highlighting your Warlock's individuality.

Summary

The "Fiend" and "Great Old One" patrons offer Warlocks entirely different possibilities.

• Recommended for Fiend: Players who want to balance stable damage output with high survivability. Ideal for those who prefer a self-sufficient attacker that pushes forward while defeating enemies, or for Warlock beginners.
• Recommended for Great Old One: Players who want to pursue unique and powerful tactics, specifically neutralizing enemies through critical hits. An advanced option for those who enjoy the process of constructing builds by combining equipment and feats.

Ultimately, the choice depends on your playstyle. Using this article as a guide, create your ultimate Warlock and enjoy your adventures in Faerûn.
