You have learned to cast spells. The information below details how you use those rules as a Dramaturge.
Cantrips
You know two cantrips of your choice from the Bard spell list (see that class's section for its list). Minor Illusion and Vicious Mockery are recommended. Whenever you gain a Dancer level, you can replace one of these cantrips with another cantrip of your choice from the Bard spell list.
When you reach Dancer level 10, you learn another Bard cantrip of your choice.
Spell Slots
The Dramaturge Spellcasting table shows how many spell slots you have to cast your level 1+ spells. You regain all expended slots when you finish a Long Rest.
Prepared Spells of Level 1+
You prepare the list of level 1+ spells that are available for you to cast with this feature. To start, choose three level 1 spells from the Bard spell list. Cure Wounds, Hideous Laughter, and Silent Image are recommended.
The number of spells on your list increases as you gain Dancer levels, as shown in the Prepared Spells column of the Dramaturge Spellcasting table. Whenever that number increases, choose additional spells from the Bard spell list until the number of spells on your list matches the number on the table. The chosen spells must be of a level for which you have spell slots. For example, if you're a level 7 Dancer, your list of prepared spells can include five Bard spells of levels 1 and 2 in any combination.
Changing Your Prepared Spells
Whenever you gain a Dancer level, you can replace one spell on your list with another Bard spell for which you have spell slots.
Spellcasting Ability
Charisma is your spellcasting ability for your Bard spells.
Spellcasting Focus
You can use a Disguise Kit as a Spellcasting Focus for your Bard spells.
