Unfettered Spellcasting

You have learned how to cast spells in the worst situations and environments, circumventing common restrictions and restraints. You gain the following benefits: 

Ability Score Increase. Increase your Charisma Score by 1, to a maximum of 20. 

Creative Workarounds. If an effect or spell would prevent you from casting a spell by preventing you from performing the Verbal or Somatic component of the spell or by making it impossible to see a valid target for the spell, you can still cast the spell on a chosen target in the spell’s normal range if you succeed on a Charisma Saving Throw against the effect’s Save DC. All other restrictions apply towards the casting of the spell.
