To prepare spells in Baldur's Gate 3 (BG3), players who control classes like Clerics, Druids, Paladins, and Wizards must prepare spells to be able to use them. The number of spells that can be prepared depends on your character level and spellcasting ability modifier. You can prepare spells at level-up or outside of combat by accessing your Spellbook. Here are the main steps to prepare spells:
- When leveling up, select the "Prepare Spells" option on the left sidebar of your level-up screen. You can remove any currently prepared spells to free up slots and choose new spells from your known spells list.
- Outside of combat, open your Spellbook by pressing 'K' on keyboard and mouse or accessing it via the controller's radial menu. From there, remove prepared spells to make room for the new ones and select the spells to prepare. The number of spells you can prepare is limited based on your level and class.
- You cannot prepare or change spells during combat.
- For classes other than Clerics, Druids, Paladins, and Wizards (like Bards, Sorcerers, Warlocks, Eldritch Knights, etc.), you can only replace one spell during level-up, not prepare freely like the others.
- If you want to do a full rebuild of spells and character, you can respec with an NPC named Withers for a fee.
In summary, the process revolves around managing your Spellbook to select a limited number of spells that are prepared and ready to be used before combat or at level-up.
