Dragon Domain
Dragons are known for many things: mastery of the most unforgiving environments, sagacity, long life, and an eternal hunger for ever more wealth and power. Those who worship dragons, or the gods of dragons, might strive to emulate several or perhaps all of these qualities themselves.
Bonus Proficiencies
When you choose this domain at 1st level, you gain proficiency in Arcana, and your proficiency bonus is doubled for any ability check you make that uses this skill. You also gain advantage on saving throws against being frightened.
Channel Divinity: Charmer of Reptiles
Starting at 2nd level, you can use your Channel Divinity to charm nonintelligent reptiles. As an action, you present your holy symbol and invoke the name of your deity. Each reptilian beast within 30 feet of you that can see you must make a successful Wisdom saving throw or be charmed by you for 1 minute or until it takes damage. While a reptile is charmed by you, it is friendly to you and to other creatures you designate.
Dragon’s Resistance
Starting at 6th level, you can call on the might of draconic resilience to protect you. When you fail a saving throw, you can use a reaction to succeed on that saving throw instead. Once you use this feature, you can’t use it again until you finish a long rest.
Divine Strike
At 8th level, you gain the ability to infuse your weapon strikes with divine energy. Once on each of your turns, when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 damage of the type dealt by the weapon to the target. When you reach 14th level, the extra damage increases to 2d8.
Frightful Presence
At 17th level, as an action, you can use a Frightful Presence like that of a dragon’s. You must finish a short or long rest before using it again.
Frightful Presence. Each creature of your choice that is within 60 feet of you and aware of you must succeed on a DC 16 Wisdom saving throw or become frightened for 1 minute. A frightened creature repeats the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to your Frightful Presence for the next 24 hours.
