Ancient Historian

Your study of history rewards you with the following benefits:

• Increase your Intelligence score by 1, to a maximum of 20.
• You gain proficiency in the History , Arcana and Religion skills. If you are already proficient in either of those skills, you add double your proficiency bonus to checks you make with it.
• When you take the Help action to aid another creature’s ability check, you can make a DC 15 Intelligence (History or Arcana) check. On a success, that creature’s check gains a bonus equal to your proficiency bonus, as you share pertinent advice and historical examples. To receive this bonus, the creature must be able to understand what you’re saying.
