Class Purist; Level 21 Third-Caster

You have chosen to continue the focus of your research and practices on the study you've always pursued, becoming a pioneer and scholar in your respective field, granting you the following benefits:

• The number of spell slots you possess, from the lowest level to the highest, are now 4/3/3/2
• You learn one spell from the Sorcerer's spell list, which will use your Constitution as the spellcasting modifier when you cast it (instead of the class default)
