Pureblood Spellcasting
You know the poison spray cantrip. Starting at 3rd level, you can also cast suggestion with this trait. Once you cast it, you can't do so again until you finish a long rest. Charisma is your spellcasting ability for these spells.
Adaptive Resistance
When you are targeted by a spell or caught within the area of effect of a spell, as a reaction you may toughen yourself to magical energy. You have advantage on the next saving throw you make against a spell or other magical effect. You can use this feature a number of times equal to your Charisma modifier, and you regain any expended uses when you finish a long rest.
