You can spend some time while camping to reflect on the events of the last 24 hours. While sitting with companions, you take 10 minutes to embroider moments from the previous day and talk about the activities you took part in as a group. Anyone who takes part in this activity can make a single knowledge check (Arcana, History or Lore) to recall information they may have missed from the previous day. 

DC for the check and relevant information is decided by the DM. There may be no relevant information, in which case no check is made.
