Ember of the Fire Giant

Prerequisite: 4th Level, Strike of the Giants (Fire Giant) Feat

You've manifested the fiery combat emblematic of fire giants, granting you the following benefits:

• Ability Score Increase. Increase your Strength, Constitution, or Wisdom score by 1, to a maximum of 20.
• Born of Flame. You have resistance to fire damage.
• Searing Ignition. When you take the Attack action on your turn, you can replace a single attack with a magical burst of flame. Each creature of your choice within 15 feet of you that can see you must make a Dexterity saving throw (DC equals 8 + your proficiency bonus + the modifier of the ability increased by this feat). On a failed save, a creature takes fire damage equal to 1d8 + your proficiency bonus, and it is blinded until the start of your next turn. On a successful save, the creature takes half as much damage and isn't blinded. You can use your Searing Ignition a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
