The Divination School may be the strongest subclass of Wizard, or at least, the strongest one in a chess match. Here is a guide on how to build a mean prophetic force in Baldur’s Gate 3.

Divination Wizards are all about their Portents. Thissubclassfeature allows them to pre-roll a few amounts of dice (Portents) every time they wake up as if they had a premonition in their dreams. Later during the day, they can swap any rolls made by themselves, an ally, or a foe, for any of the numbers they had rolled in their Portents.
From this ability, Divination Wizards can dictate the rules of combat using their portents to aid allies or thwart enemies. Learning how to use the dice in critical moments is key to making best use of their divination potential.

When you reach level 6, you will get the featureExpert Divination, which upon finishing a short rest will give you a random prophecy. Since completing the prophecy will give another Portent, you should prioritize that whenever you have the chance.

SinceWizardsdon’t have access to armour or shields,Humans are an obvious choice. Their feature Civil Militia gives you access to Light Armour and Shields.
Halflingsare a good alternative for their Lucky trait, which allows them to reroll 1s. Combine that with the Portent dice and you will have even more control of your luck. However, you would be sacrificing shields and +2 AC for a trait that only becomes useful five per cent of the times you roll.

That is why I chose theHalf-Elf. And on top of Civil Militia, they have Darkvision and Advantage against being charmed.

Intelligence is your main Ability, but you will need a strong Constitution to compensate for the d6 of HP you get each level, and to improve your Concentration Saving Throws. This is what my Wizard looked like straight out of the oven:

I went full Divination Wizard for the 12 levels. There’s an option to multiclass into Sorcerer (3) and get Metamagic options, but that would mean losing access to some 5th and all 6th-level spell slots. For a character that is Support and needs the higher spell slots toCounterspell, it is best to keep it vanilla.
The spells I chose aren’t the most important part of the class, since Wizards can learn any spells from scrolls. However, this guide aims to highlightthe most powerful spellsat each level.

How to play a Divination Wizard in BG3
If your party is an orchestra, The Divination Wizard is the director. I make my Wizard stand somewhere they can see everyone (otherwise they can’t use their Portent on them), I attempt to keep them safe and I never spend their reactions on opportunity attacks; you should save those for Portents or to cast Counterspell.
Since Wizards can learn spells from scrolls, you can make them even more powerful with the secret spells that can’t be learned otherwise, such asArtistry of Waror Dethrone.
