How to Build Cave and Cliff Encounters: A Step-by-Step Terrain Guide

Quick answer

Build cave and cliff encounters in four passes: sketch the footprint and vertical layers, place the floor and elevation pieces first, add cavern walls and transition pieces, then stage lighting and props. Keep the first pass flat and cheap, and only commit to height once the play space works. Freestanding pieces and modular sets let you adjust the cliff face without rebuilding the whole layout.

Cave and cliff encounters live or die on two things: a playable footprint and a believable vertical edge. If the floor is too tight, the cliff becomes decoration instead of terrain. If the cliff is too tall or too fragile, players knock it over every time they move a mini.

This process walks through the same order every time: plan the footprint, build the floor, stack the elevation, close the cave walls, then stage the reveal. Each step includes the mistake that most often forces a rebuild.

Step 1: Sketch the footprint and vertical layers

Before you place a single piece, draw the encounter on paper. Mark where the party enters, where the fight happens, and where the cliff edge sits. A useful rule is one 4x4-inch zone of open floor per combatant, plus a clear lane for movement. If the sketch does not fit your table, the build will not fit either.

Then mark elevation. Two or three levels are usually enough for a cliff encounter: a low ledge, a mid shelf, and a high overlook. More levels look dramatic but slow play and make minis hard to reach. Decide now which level the objective, treasure, or boss sits on.

• Common mistake: drawing the cliff first and squeezing the floor around it. Draw the fight first, then the cliff.

Step 2: Lay the cave floor before anything else

Build the ground layer flat and complete. Use your cavern floor tiles or a battle mat to establish the full footprint, including the area under the future cliff. This is the cheapest moment to change the layout, because nothing is stacked yet.

Test reach with a mini in hand. If you cannot comfortably place and move a miniature in the center of the encounter, widen the floor now. A cave terrain build that plays well at floor level is easier to extend upward later.

• Checkpoint: every mini can reach the center of the encounter without moving terrain.

Step 3: Stack the cliff in stable, reachable tiers

Add elevation in tiers rather than one tall wall. Wide, low steps are more stable and let you place minis on each level. If you use cavern wall pieces as the cliff face, place the largest and most stable pieces at the base and save narrow or decorative pieces for the top.

Leave at least one climbable route, such as a slope, rubble pile, or stacked ledges. A cliff with no route turns into a shooting gallery and removes player choice. If the encounter needs a hard climb, make it a skill check rather than an impossible wall.

• Common mistake: building the cliff as a single vertical face with no ledge wide enough to stand on.

Step 4: Close the cave walls and transitions

Once the floor and elevation hold, fill the perimeter with cave walls, arches, and transition pieces. This is where freestanding wall elements earn their place: you can drop them in to close a sightline or open a passage without disturbing the stacked cliff.

Work around the table, not from one side, so you notice gaps at eye level. Leave deliberate openings for entrances, side tunnels, and line of sight. A cavern terrain layout reads better when players can see two or three ways through it.

• Checkpoint: walk around the table once and confirm no accidental gaps let players see into sealed areas.

Step 5: Stage lighting and props for the reveal

Caves benefit more from directional light than from bright, even light. Place a light source low and to one side so the cliff face casts shadows and the depth reads from across the table. Translucent pieces look especially good when lit from underneath, which turns a flat floor into a glowing hazard.

Add props last: cages, rubble, bones, and objective markers. Put them where they create a decision, not just decoration. A cage in the open is scenery; a cage behind the cliff edge is a rescue mission.

• Common mistake: lighting the whole cave evenly, which flattens the cliff and hides the elevation you built.

Step 6: Playtest and adjust between sessions

Run one round of combat before the real session. Watch where players move, where they bunch up, and where the terrain gets bumped. Note the two or three pieces that shifted or blocked reach, and fix only those.

Keep adjustments small. Swapping one wall piece or widening one ledge is faster than rebuilding the cliff. If the encounter worked, photograph the layout so you can rebuild it later without re-solving the same problems.

• Checkpoint: after one round, no piece has moved and every player can reach their mini.

Cave and cliff build order at a glance

1. 1. Sketch footprint and layers: Draw the fight first, then mark two or three elevation levels. If it does not fit the sketch, it will not fit the table.
2. 2. Lay the full floor: Build the ground layer flat and complete, including under the future cliff. Check reach with a mini before stacking anything.
3. 3. Stack stable cliff tiers: Add wide, low steps and keep at least one climbable route. Avoid one tall vertical face with no standing room.
4. 4. Close walls and transitions: Add cave walls, arches, and freestanding pieces around the perimeter. Walk the table to catch gaps at eye level.
5. 5. Stage light and props: Use directional light and place cages or objectives where they create choices. Even light flattens the cliff you just built.
6. 6. Playtest one round and adjust: Fix only the pieces that shifted, blocked reach, or broke line of sight. Photograph the layout once it works.

Pieces that make cave and cliff builds easier

• Freestanding Low Arch Cavern Wall (Painted): An individual painted Dwarvenite piece from the Caverns line and the Caverns Deep (KS6) range, designed as a freestanding wall element for stone cavern setups and transitions. Because it stands on its own, you can close a sightline or add a transition without unstacking the cliff behind it.
• Core Pack for Encounter 3: Soulcage Vault (Painted): A bundled set with a wide variety of pieces including lava cavern building pieces and large magma rivers, cast in translucent Dwarvenite; it looks best lit from underneath with DF Light Panels, with 5 recommended for this set. Useful when the cave encounter needs a glowing hazard layer; plan the light panels as part of the build, not an afterthought.
• Plaguestone - Curved Cages Pack (Painted): Includes 6 Curved Cages, 2 Curved Cage with Doors, 2 Straight Broken Cages, and 2 Straight Cages, made to work with Dungeon of Doom's cages. Gives the cliff encounter an objective to fight over, and the broken cages let you show that something already escaped.
• Big Buttress Pack (Unpainted): Contains 12 pieces: 4 buttresses, 4 perched gargoyles, and 4 flying buttresses, with accessory holes on the flying buttresses for the included gargoyles or other pole accessories. Best for ruined surface structures above a cliff, where the buttresses brace a wall and the gargoyles add a watchful silhouette.

Cave and cliff encounters reward order more than volume. Plan the footprint, build the floor flat, stack elevation in reachable tiers, then close the walls and stage the reveal. Adjust one piece at a time after a playtest, and the same layout will serve you for years.
