Rakshasa's Resilience

You’ve manifested some of the power of Rakshasas, granting you the following benefits:

• Increase your Dexterity, Constitution, or Charisma by 1, to a maximum of 20.
• Your walking speed increases by 5 feet.
• You gain fluency in Infernal.
• You learn the disguise self spell. You can cast this spell without expending a spell slot. You can cast this spell in this way a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. You can also cast this spell using spell slots you have. The spell’s spellcasting ability is Charisma.
• When you finish a long rest, you can choose to give yourself vulnerability to piercing damage for 24 hours. When you choose to give yourself vulnerability to piercing damage, you can choose to have either resistance to bludgeoning and slashing damage, or limited magic immunity. If you choose resistance to bludgeoning and slashing damage, you gain resistance to nonmagical bludgeoning and slashing damage for 24 hours. If you choose limited magic immunity, if you would be affected or detected by a spell of a level no greater than your proficiency bonus, you can roll a d6. If the number you roll is no lower than the spell level, you are not affected by the spell unless you wish to be, otherwise you have advantage on any saving throw the spell forces you to make.
