• Increase one ability score of your choice by 1, to a maximum of 20.
• You can pass off as another person to someone who hasn't seen you in the past week.  A successful Wisdom (Insight) check contested by your Charisma (Deception) check allows them to remember who you are.
• Once per long rest, while under the effect of a spell that requires concentration, you can attempt to make a Charisma saving throw against their spellcasting save DC.  If successful, they drop concentration on you.
