History Check to Recall Last Session

At the start of a session, let all your players (on their character) make a History Check.
The highest rolling players, can start recapping what happened last session (if they want to use notes that they took, allow this!).
As DM, decide if this was accurate and complete enough to give them Heroic Inspiration as a reward.
If it was not accurate and complete enough, give the second highest rolled player a chance to fill in the blanks and obtain the Heroic Inspiration instead.
If none of the players remember the important details, as DM you can still fill these in and no one gets Heroic Inpsiration.

Several of our playtesting DMs noticed players paying more attention because of this Variant Rule.
**Paring this Variant Rule with the Heroic Inspiration Usage Variant Rule has shown to be an interesting and regular (yet not too overpowered) source of Heroic Inspiration.**
