Learning From History [History]

Requires Linguist, Objects of Legend, or Martial Adept Feats

When in a historically significant area, like a city, ruin,
battlefield, or stronghold, or when preparing to enter one, you
can spend 10 minutes regaling creatures around you with
tales of the locale’s past; Until the next long rest, you and
each creature that listens to the entirety of this lesson gains
advantage on initiative checks while in the area.
In addition, you can choose a number of creatures up to your
Intelligence modifier (minimum 1) and give each of them a
Historical Accuracy die (a d6). Once within the next 8 hours,
the creature can roll the die and add the result to one ability
check, attack roll, or saving throw it makes. A creature can only
have one Historical Accuracy die at a time and can’t use more
than one per long rest per location.
