Draconic Disciple

At 3rd-level you can channel your draconic ki to imbue your unarmed strikes with the essence of a dragon’s breath and to use your connection with draconic creatures to magnify your presence. You gain the following benefits:

• When you damage a target with an unarmed strike, you can change the damage type to acid, cold, fire, lightning, or poison.
• If you can’t already, you learn to speak, read, and write Draconic.
• If you fail a Charisma (Intimidation) or Charisma (Persuasion) check, you can use your reaction to reroll the check, as you tap into the mighty presence of dragons. Once this feature turns a failure into a success, you can’t use it again until you finish a long rest.
