How to Change Spells in BG3: A Complete Guide

In Baldur’s Gate 3 (BG3), spellcasting is one of the most exciting and strategic parts of the game. Knowing how to change spells in BG3 can make a huge difference in how effective your character is during battles or exploration. Whether you’re a Wizard, Cleric, or Druid, understanding the spell system will help you tailor your abilities to any situation.

This guide explains step-by-step how to change, prepare, and manage spells for each type of spellcaster, plus some useful tips to make your gameplay smoother and more powerful.

Understanding Spell Types in BG3

Before learning how to change spells in BG3, it’s important to know how the game’s magic system works. BG3, based on Dungeons & Dragons 5th Edition (D&D 5e) rules, divides spells into two main categories:

• Prepared Spells: Used by classes like Clerics, Druids, and Paladins. These characters can choose from a wide list of spells each day.
• Learned Spells: Used by Wizards, Warlocks, and Sorcerers. These characters permanently learn spells and can only prepare or replace them at certain times.

Knowing your spellcasting class type helps determine when and how you can switch spells.

How to Change Spells in BG3 for Each Class

1. Wizards

Wizards have the unique ability to learn new spells from scrolls or leveling up. However, they can only prepare a limited number of spells at a time.

To change spells as a Wizard in BG3:

1. Open your Spellbook by pressing “K” (default key).
2. You’ll see two sections — known spells and prepared spells.
3. To change them, simply unprepare a spell by clicking on it, then prepare another from your known list.
4. You can do this anytime outside combat, usually while resting or exploring.

Tip: Wizards can learn additional spells by using scrolls found throughout the game. Right-click a scroll and choose “Learn Spell.”

2. Clerics and Druids

Clerics and Druids can prepare spells from their entire class spell list every day, but they can only use a limited number depending on their level and Wisdom modifier.

To change spells as a Cleric or Druid:

1. Go to Camp and choose to Long Rest.
2. During the resting screen, open your Spellbook (K).
3. Select or deselect spells to adjust your Prepared Spells list.
4. After resting, your new spells will be ready for use.

Tip: Always prepare healing, buffing, and utility spells before long journeys — you can switch to offensive magic later.

3. Sorcerers and Warlocks

Unlike Wizards, Sorcerers and Warlocks cannot freely change spells after learning them. Their spell choices are permanent — at least until leveling up.

Here’s how to change spells as a Sorcerer or Warlock:

1. When you level up, you’ll get an option to replace one known spell with another from your spell list.
2. Choose carefully — once you confirm, the change is permanent until the next level up.

Tip: Sorcerers can use Metamagic to modify how spells behave, offering flexibility even without changing spells often.

4. Paladins and Rangers

Paladins and Rangers are half-casters, meaning they gain spellcasting abilities later in the game. They work similarly to Clerics — you must prepare spells after a Long Rest.

To change spells:

1. Open your Spellbook while resting.
2. Add or remove spells from your prepared list.
3. Confirm the selection before finishing your Long Rest.

When You Can’t Change Spells

Many players wonder why they can’t swap spells during combat or at random moments. Here’s why:

• You can’t change spells during combat — only outside of it or during rests.
• Some classes (like Sorcerers) are restricted to level-up spell changes.
• You may also need a Long Rest to finalize your new prepared spell list.

If you find that the change spells option isn’t working, ensure you are outside combat and not in a restricted area like dialogue or a scripted event.

Tips for Managing Spells in BG3

1. Plan Ahead: Before heading into combat-heavy areas, adjust your spell list based on expected challenges.
2. Use Scrolls Wisely: Wizards can expand their spell collection significantly by learning from scrolls.
3. Balance Offense and Defense: Always keep healing and utility spells handy alongside offensive magic.
4. Rest Strategically: Use Long Rests to reset spells and switch tactics between fights.
5. Experiment: Try different spell combinations to find what best fits your party strategy.
