You are considered an Elemental
You are Medium or Small. You choose when you select this race.
You can see in dim light within 60 feet of you as if it were bright light and in darkness as if it were dim light. You discern colors in that darkness only as shades of gray.
You have resistance to fire damage.
You know the fire bolt and produce flame cantrip. Starting at 3rd level, you can cast the burning hands spell with this trait. Starting at 5th level, you can also cast the flaming sphere spell with this trait, without requiring a material component. Once you cast burning hands or flaming sphere with this trait, you can’t cast that spell with it again until you finish a long rest. You can also cast either of those spells using any spell slots you have of the appropriate level.
Intelligence, Wisdom, or Charisma is your spellcasting ability for these spells when you cast them with this trait (choose when you select this race).
You have a strange ability to control minor fire elementals more specifically magmins. As an action, you may attempt to bind a magmin to your control. When you do so they must be within 15 feet of you and make a wisdom saving throw equal to 8 + your charisma modifier + proficiency bonus. On a failure they obey your every command. Using a bonus action you can command them to use one of their actions, if you do not use your turn to command them they take their turn trying to find something to ignite. You can only control as many magmins equal to your charisma modifier.
