But what does that have to do with the new summer blockbuster Fallen Kingdom? Let's see what you can easily steal from it:
1. Fallen Kingdom: Have the players or the people in the campaign run through an area that has now fallen into ruin? Did an old campaign fail with the players not saving Waterdeep? With Shadowdale being destroyed? Have the new players go through those ruins. Have them see the price of failure.
2. The environment as a challenge: While 4e may be hated for many reasons, it's skill challenge system had some potential. It allowed your characters to try and succeed at something with a certain number of successes needed before hitting a certain number of failures. Need to jump onto a crumbling spiral stairwell while lava burns through the roof? Need to dodge falling boulders while driving a carriage unto a boat that's leaving dock? Set some skill checks and devise some penalties for each failure. Maybe you get splashed with acid. Maybe you get jostled on the vehicle. Maybe a nearby monster gets to take a bite at you.
3. Minions: While it's great to give players equal opposition and sometimes even have them go against stronger foes, giving them numerous opportunities to knock out weaker foes gives them a chance to flex their own physical prowess.
4. New Enemies: In a game like Dungeons and Dragons, one of the most iconic monsters is the owlbear. Fallen Kingdom introduces the much cooler indoraptor, a super raptor.
