One of the most unique and satisfying builds in Baldur’s Gate 3, School of Transmutation wizard can manipulate objects, allies, enemies and even themselves to change their physical appearance and nature. This build mostly deals with using alchemic magic to change physical properties of anything around you. Too tall to pass through a burrow hole or too fat to squeeze through a slit? Worry not, just holler at your friendly neighbor Transmutation wizard and voila.
In this guide, we will solely focus on School of Transmutation wizard build and how you can use it to solve puzzles or gain an upper hand in a battle. As this build lacks proper protection against enemies, we will use a specific class to grant it the ability to use defensive measures.
Starting abilities and skills for Wizard School of Transmutation
Race: Human. The human race provides three perks in BG3. It increases the distance you can cover per turn (9m), allows you to be proficient in an additional skill while decreasing your weight load and most importantly you gain proficiency with armors, weapons and shields. As the wizard class in BG3 can’t equip shields and armors, Civil Militia feat is one of the most important one in this regard.

For BG3 cantrips, we recommend Fire Bolt, Shocking Grasp and Minor Illusion. For magic spells you can go with Magic Missile, Burning Hands, Ice Knife, Longstrider, Mage Armor and Grease.
Ability Points distribution: 8 Strength, 14, Dexterity, 15 Constitution with +1, 14 Intelligence with +2 (primary ability), 10 wisdom and 10 Charisma.
Skills: Insight, Religion, Acrobatics, Investigation and Sleight of Hand.
Prepared Spells: You can prepare three spells before starting the new adventure. Our core selection includes Magic Missile, Mage Armor and Burning Hands.
Backgrounds in Baldur’s Gate 3 give a lot of personality and backstory to any class or build. They also determine how your character will deal with a specific situation.
For the School of Transmutation wizard build in BG3, we have decided to go with the Acolyte background. This background allows you to use your insight to investigate any character and distinguish their truth from the lies. It also allows you to interact with any holy object (relic, building, scripture) to learn more about its history and origin.
