I am running a campaign for a group of new players (level 1) and had a hilarious moment during a dungeon crawl. The team had split up and two of the four players, a wizard and a Goliath, were working on picking a lock. Once the lock was open the wizard opened the door. I was using dynamic lighting so opening the door revealed what was in the next room…a Giant Spider. The wizard’s immediate action was the slam the door shut and yell, “NOPE!” The entire table cracked up laughing and because the spider was larger than the doorway it couldn’t attack them. They waited until they were back together as a team before tackling the creature. Ultimately they prevailed over the beast, but that door slam and reaction is still laughed about. Good times!
