Chase scenes are about outwitting and outrunning your opponent. They should be frantic, vivd, fast-paced. And everybody in the group should be able to contribute. I want to run this off the cuff, which means I don't want to micro-manage and plan out every last little obstacle, juggle movement speeds per character, initiative, opportunity attacks and so on.
|Eberron skycoach chase in Sharn|
I'll run chases as extended opposed skill checks. Yes, it's a reviled D&D 4e mechanic, yes we'll make it work anyway. My goal is a fast movie montage of cool situations and quick decisions, not endless fiddling with modifiers. I also want variety in the challenges; not just comparing movement speeds, but throwing up situations for the players to navigate in (hopefully) new and exciting ways. I'm choosing a system that treats a group of chasers or runners as one single entity, so that I don't have the hassle of tracking how far ahead each individual is. Speed over detail here.
Night's Black Agents has a perfect little system - I only needed to file off the serial numbers and write up a bunch of obstacles. Rules first, obstacles and persistent conditions at the bottom of the post. This is written for a 5e game in a lowish-magic setting like the City of Lankhmar. In a place with a lot of low level magic like Eberron, spice things up with feather fall tokens, boots of jumping and so on.
Optional rules for those who like more crunch are in italics. They can mostly be used independent of each other.
>> USE THIS CHASE TRACKER FOR D&D 5E [ google doc ] <<
CHASE RULESSet-up. Runners are the people trying to get away, Chasers are the ones trying to catch them. You track the distance between the two groups in an abstract way using the Lead stat. Runners need to reach a certain Lead to escape, Runners want to reduce that Lead to 0.
- Draw one box for each number of Lead on some scrap paper; track the Runner's Lead with a token like a die, a coin or a mini.
- If you're aiming for immersion, don't show the players the progress track - only describe if they're pulling away, close to getting caught, how close they are to their goal etc.
- If you really need to know exact distances, assign ranges for spells and attacks to different brackets of Lead. Lead 0-2 is 0-60 feet, Lead 3-6 is 60-200 feet, Lead 7-14 is 200-1000 feet.
Lead and Obstacles. The way you change Lead is by going through Obstacles; quick little situations you can navigate in a ton of different ways. Select Obstacles in advance or roll them as you go. Be prepared for a chase to hit the rooftops, sewers, water etc - I've included slightly longer lists for those environments.
The Runner starts with a Lead halfway to their Target, depending on the overall terrain:
- Crowded, twisty alleys, lots of obstacles: start at Lead 3, escape at Lead 6.
+1 bonus to rolls to the most agile group (highest average Dex), adjust initial Lead by 1 in their favor
- Minor obstacles: start at Lead 5, escape at Lead 10.
+1 bonus to rolls to the fastest group (highest average Speed), adjust initial Lead by 1 in their favor
- Wide open terrain: start at Lead 7, escape at Lead 14.
+1 bonus rolls to the group with the best endurance (highest average Con), adjust initial Lead by 1 in their favor
- Initial conditions: ± 1-3 to Lead for an (un)favorable start like being surprised by guards, sabotaging the opponents' cart etc.
|Have you tried just walking at street level?|
Have the group pick a leader for the round and let them describe their approach. Each group moves as one close-packed group. Every round, another player heads each group and rolls a skill check to try and overcome the Obstacle.
- Every skill is fair game, if the player can describe how they try to use it to navigate the Obstacle. Allow for crazy stunts and reward those in narration. In 5e, you can always give +d6 Inspiration for a really cool idea.
- The base difficulty for the skill check is 13.
- Each round, the head Runner may decide to raise the stakes by upping the Difficulty by 1. They may also keep it at the current level. The Difficulty may only be lowered by 1 (down to 13) when both the head Runner and Pursuer agree. This represents choosing a faster pace, a more difficult route or some other risky stratagem. Ask them to describe how they see this raise looking in the fiction.
- If the lead character wants to use a skill that their group already used before in this chase, up their Difficulty for this roll by 1 - stimulates creative solution.
- Up the difficulty by 1 if a character has headed the roll-off before - this both simulates the group getting tired and stimulates them to let everyone in the group take a turn.
Roll-off. Best roll changes Lead in that group's favor. Describe the results of the rolls, tell your players how close they are to catching or escaping their opponents, and go for the next Obstacle. If the chase is heading in a particular direction (you need to reach the boat / catch the cultist before they reach their safe house), mention how close you're getting.
- Runner fails, Pursuer succeeds: Lead shortens by 2.
- Runner and Pursuer both succeed or fail: Lead changes by 1 according to whose margin was greater. In case of an exact tie, keep the Lead as-is.
- Runner succeeds, Pursuer fails: Lead lengthens by 2.
- If either party rolls a 1, add a Condition and up the Difficulty by 1. (See bottom of post for examples). If either party rolls a 20, they can remove an ongoing Condition and reduce the Difficulty by 1.
|The Goblin Chase, by Sean Andrew Murray|
RUNNING A CHASEPick an Obstacle. Describe quickly what the group sees - this is all happening on the run. First impressions, one big hit of flavor, then boom: who takes point? What do you do?
You'll get questions from your group. Fine, use those to flesh out the scene. Try to keep that to under one minute though, this is about keeping a frantic pace.
Have the head Runner for the group describe their approach and pick a skill for it, then the same for the Pursuers. Describe results: this is going to be chaotic, lean into that. Reward crazy ideas with cool descriptions, then on to the next Obstacle!
THINKING ABOUT OBSTACLESIdeally, Obstacles are situations that the players can decide to tackle in lots of different ways, not a straightjacket to which there is only one answer. So, "You run into an alley full of street food vendors, with drunks and hot grease everywhere - what do you do?", instead of "there's a closed fence - roll for lock picking!")
My advice is to pick or roll a bunch of Obstacles ahead of time so you can keep up the pace during the chase without having to consult tables all the time. Of course if your group decides to head for the roof tops / into the sewers / back to the streets, you'll need to find appropriate new Obstacles, but it pays to have some pre-selected.
OPTIONAL CHASE RULES
Only recommended if you've got the basic Chase rhythm down.
- One Runner and one Pursuer character may choose to take an action (ranged attack or cast a spell) to try and change the Difficulty for the round. This always raises their group's Difficulty by 1.
For instance, a druid could summon a thicket of brambles to tangle his pursuers and give them +1 Difficulty, or a wizard could cast haste to give his group an ongoing -1 Difficulty. The idea is not to drop into blow-by-blow combat during a Chase - that's what the combat rules are for. Reflect the effect of the player's action in the round's Difficulty and move on.
- Runners can choose to split the party at the start of a new round; the Pursuers then have the option of sticking with one group or splitting up as well. Deception / Insight checks might be necessary if the Runners want to hide which group has the MacGuffin, hostage, etc. (No casting spells or attacks this round; this counts as one character's action - see below.)
- If both groups split up, run this as two separate Leads to close or open up. Botches and Criticals still inflict / alleviate Conditions.
- If the Pursuers stick together, increase the Difficulty for their Runners by +1 to represent them being hounded by a comparatively larger group. The other Runners escape.
- At Lead [target -2] or higher, the Runner may make an additional skill check at Difficulty +2 to make a sudden escape; the lead character decides how they suddenly manage to give their Pursuers the slip. Failure ups their Difficulty by 1 for the rest of the chase. Depending on your system, inflict subdual damage or exhaustion as a cart crashes, ankles are twisted after a long drop and so on. As before, skills used already once before incure a +1 Difficulty, so just spamming "we run extra hard and roll Athletics" is not a winning strategy.
- At Lead 2 or below, the Pursuer may make an additional check at Difficulty +2 to grab the Runner in a final burst of speed. The lead Pursuer describes how this happens and which skill they want to use. Failure ups the Pursuers' Difficulty by 1 for the rest of the chase. Depending on your system, inflict subdual damage or exhaustion.
OBSTACLESFINALLY, shit to pepper your chase with. Either plan these out ahead of time (so you can foreshadow) or roll as you go along. Sewers and rooftops have longer lists, because face it, your players will go there first chance they get.

CONDITIONSWhen either Pursuers or Runners roll a 1 on their skill check, inflict an ongoing Condition on everyone. If a party rolls a 20, they can choose to end one condition.
Every condition inflicts an ongoing problem on the Runners and Pursuers. The lead character in every group rolls a check against Difficulty every round or the group suffers a
- Flash rains block sight, extinguish torches, make everything slippery. Dex save or the group loses 1 Lead.
- Lightning storm disorients everyone with flashes and thunder. Wisdom save or the group loses 1 Lead.
- Fire! A band of arsonists - or cultists? - has set fire to the neighbourhood. Dex save or everyone in the group takes d6 damage.
- CLOUD OF HATRED. A hidden cult has summoned the Cloud of Hate. People riot in the streets. Wisdom save or the group members inflict d6 damage on each other; add +1 to the Difficulty of Obstacles involving people.
- Festival! An obscure faith demands an impromptu celebration. Fireworks, loud trumpets, jostling crowds. Persuasion check or the group loses 1 Lead.
- The stars are right. Mad visions plague the living. Intelligence save or reroll your chase check.
- All Thieves' Night. Impromptu celebration by the followers of a local thieving god. Perception roll or a random group member loses a small item like a purce, ring or amulet. Any objects the group just stole (probably the reason they're being chased) have a 1-in-6 chance of being stolen this way. If the roll misses by 5 or less, the group realizes the theft and can try to chase the thief. If not, they realize next round and can give chase at a higher Lead.
