Steam Hydromancer

You have learned techniques to direct your hydromancy spells through water vapor, and to direct fire spells through bodies of water, gaining the following benefits:

• You learn the fog cloud spell and can cast it once without expending a spell slot. You regain the ability to cast this spell in this way when you finish a long rest.
• You can treat an area of fog, mist, or steam as a body of water when casting spells with the hydromancy tag.
• When you cast a spell that deals fire damage, it gains the hydromancy tag with a hydromancy radius of 30 feet.
• Fire damage dealt by spells you cast using hydromancy ignores resistance granted from being underwater.
