Baldur’s Gate 3 Knowledge Domain Cleric Build And Subclass Guide

Knowledge Domain Cleric subclass in Baldur's Gate 3 are the kings of disabling if you have the right build for your character.

Knowledge Domain Clerics in BG3 should be evident from their names. This Cleric subclass is proficient in some extra skills by default without you having to unlock those skills. The Baldur’s Gate 3 Knowledge Domain Cleric build relies on disabling enemies through mind-altering status effects like Sleep, Calm Emotions, and Dominate Person. On top of that, the Knowledge Domain subclass can also boost the damage done by Cantrips by scaling with Wisdom ability.

How good is Knowledge Domain Cleric in BG3?

Knowledge domain Clerics in BG3 are amazing for exploration and gaining the upper hand during dialogue sequences. You can use this class to pass multiple dialogue checks with ease. Knowledge Clerics help their allies during combat scenarios by supporting and controlling the crowd with their specialized cantrips and spells. 

However, Knowledge Domain Clerics lack proper movement speed and can’t equip heavy armor. Unlike the other cleric classes, like Life Domain, their spell and cantrip selection is quite limited.

Knowledge Domain Cleric Multiclass in BG3

You can always multiclass your Knowledge Domain Cleric with fighter class (10/2) or Wizard (11/1) to gain access to some unique class features. However, this will make you lose either the War Caster feat or the level 6 spell slot. Our knowledge cleric build is heavily focused on using its feats to maximize the spell casting, so multiclass is not a good option, in my opinion.
