You have Darkvision with a range of 60 feet.

You can speak, read and write Infernal

You know the Thaumaturgy cantrip. When you cast it with this trait, the spell uses the same spellcasting ability you use for your Fiendish Bloodline trait.

You are the recipient of a bloodline that grants you supernatural abilities.

When you reach character levels 3 and 5, you learn a higher-level spell, as shown on the table. You always have that spell prepared. You can cast it once without a spell slot, and you regain the ability to cast it in that way when you finish a Long Rest. You can also cast the spell using any spell slots you have of the appropriate level. Charisma is your spellcasting ability for these spells.

Your character knows at least three languages: Common plus two languages you roll or choose from the Standard Languages table. Knowledge of a language means your character can communicate in it, read it, and write it. Your class and other features might also give you languages.

The Standard Languages table lists languages that are widespread on D&D worlds. Every player character knows Common, which originated in the planar metropolis of Sigil, the hub of the multiverse. The other standard languages originated with the first members of the most prominent species in the worlds of D&D and have since spread widely.

You can increase 3 ability scores by 1 (+1,+1,+1) or one ability score by 2 and another ability score by 1 (+2,+1).
