Baldur's Gate 3 wizard: Class Guide and Progression

Overview of the Wizard in Baldur's Gate 3

The Wizard is a quintessential magic-wielding class in Baldur's Gate 3. Unlike other casters who might rely on innate talent or divine pacts, Wizards master the arcane arts through rigorous study, research, and the practical application of ancient spells. By specializing in specific schools of magic, they provide versatile support, immense area-of-effect damage, and critical utility to any adventuring party.

Wizards rely primarily on Intelligence for their spellcasting effectiveness. Managing your Intelligence score is vital, as it directly influences your spell save DC and the number of spells you can prepare at any given time.

Understanding Wizard Spellcasting

The core of the Wizard experience is the Spellbook. Unlike other classes that may have a fixed list of spells, Wizards possess a unique ability to expand their repertoire significantly beyond their level-up choices.

Transcribing Scrolls

One of the most powerful features of the Wizard is Transcribing. If you find a spell scroll containing a spell that is on the Wizard class list—and you have a spell slot of the appropriate level—you can permanently add that spell to your spellbook. This process costs 50 gold per level of the spell and consumes the scroll. This allows a versatile Wizard to eventually learn a vast array of spells, provided they have the gold and the scrolls to support their research.

Prepared Spells

While your spellbook may contain many spells, you can only have a limited number "prepared" for combat. You can swap these prepared spells at any time while you are out of combat. The number of spells you can prepare is calculated as: Wizard Level + Intelligence Modifier (Minimum of 1).

Arcane Recovery

Wizards are not left helpless when their spell slots run dry. The Arcane Recovery feature allows you to replenish expended spell slots while out of combat once per day. The number of charges increases as you level up, allowing you to recover higher-level or multiple lower-level slots depending on your needs.

Wizard Subclasses (Schools of Magic)

At Level 2, you must choose your specialization, known as a School of Magic. Each school offers a "Savant" passive, which halves the cost of copying spells of that school from scrolls into your spellbook.

• Abjuration School: Focused on protection and defense. Features include the Arcane Ward, which helps mitigate incoming damage.
• Subclass check: Verify the available Wizard subclass names and feature descriptions in the current in-game level-up screen before planning around a specific school.
• Conjuration School: Masters of teleportation and summoning. Features include Minor Conjuration: Create Water.
• Divination School: Allows for the manipulation of fate through the Portent feature.
• Enchantment School: Focuses on controlling the minds of others with abilities like Hypnotic Gaze.
• Evocation School: The masters of raw magical destruction. Their signature Sculpt Spells feature ensures your area-of-effect spells do not harm your allies.
• Illusion School: Experts in deception, gaining features like Improved Minor Illusion.
• Necromancy School: Harnesses the power of death, gaining Grim Harvest to recover hit points when killing enemies with spells.
• Transmutation School: Allows for manipulation of matter and alchemy, featuring Experimental Alchemy.

Tips for Playing a Wizard

1. Prioritize Intelligence: Since your spell effectiveness is tied to your INT modifier, ensure you prioritize this in your character creation and Feat choices.
2. Manage Your Gold: Because transcribing scrolls is expensive, keep an eye on your gold reserves. Prioritize copying spells that offer high utility or damage potential.
3. Utilize Concentration: Many powerful spells require concentration. Protect your Wizard by increasing your Constitution score or taking Feats that improve your concentration checks.
4. Balance Your Spellbook: Ensure your prepared spells cover a variety of needs, including crowd control, utility, and damage.
5. Multiclassing: While the Wizard is a powerful standalone class, remember that no proficiencies are granted when multiclassing into a Wizard. Plan your progression carefully if you intend to dip into other classes.

Source-aware planning notes

Use class guidance to compare trade-offs, not to declare one option universally correct. The collected material can help you frame a role, a progression idea, or a decision point, while your party composition and preferred difficulty determine whether it feels good in practice. Record any detail that is described only by a community guide as a player report, and re-check it if the game receives an update. Use the article's headings as a worksheet: write down the confirmed premise, the next action, and the point at which you need to verify a newer source. This approach keeps the guide useful for a first pass while making its limits visible. It also prevents a concise community summary from being mistaken for a complete rulebook. When you adapt the advice to a different party, difficulty, platform, or patch, preserve the original wording and add your own observation separately. A careful note is more valuable than a confident detail that the collected evidence cannot support.

FAQ

How do I learn new spells as a Wizard?

You learn spells automatically upon leveling up. Additionally, you can learn any spell from the Wizard list by using the Transcribe feature on a found scroll, provided you have a spell slot of that level and sufficient gold.

Can I change my prepared spells?

Yes, you can swap your prepared spells at any time while you are out of combat. You are only limited by the number of slots allowed by your current level and Intelligence modifier.

What is the primary benefit of choosing a specific School of Magic?

Each school provides a "Savant" passive, which halves the gold cost of transcribing spells of that school. Furthermore, each school grants unique, powerful class features at levels 2, 6, and 10 that significantly alter your playstyle.
