Preparing Spells
If you have a list of level 1+ spells you prepare, your spellcasting feature specifies when you can change the list and the number of spells you can change, as summarized in the Spell Preparation by Class table.
Spell Preparation by Class
| Class | Change When You \ldots | Number of Spells |
|---|---|---|
| Bard | Gain a level | One |
| Cleric | Finish a Long Rest | Any |
| Druid | Finish a Long Rest | Any |
| Paladin | Finish a Long Rest | One |
| Ranger | Finish a Long Rest | One |
| Sorcerer | Gain a level | One |
| Warlock | Gain a level | One |
| Wizard | Finish a Long Rest | Any |
Most spellcasting monsters don't change their lists of prepared spells, but the GM is free to alter them.
Always-Prepared Spells
Certain features might give you a spell that you always have prepared. If you also have a list of prepared spells that you can change, a spell that you always have prepared doesn't count against the number of spells on that list.
