When creating unforgettable Dungeons & Dragons adventures, the atmosphere and setting are just as important as characters and plot. One of the most immersive experiences can be found deep within a dungeon. As someone who has crafted various underground dungeons for my campaigns, I recently decided to channel my creativity into capturing these dark, mysterious places through watercolor sketches. Join me on this journey as I explore the creation of an underground D&D dungeon map in watercolor. I hope to inspire fellow adventurers and artists and share tips on blending artistry with storytelling.
The Inspiration Behind the Dungeon
Dungeons in D&D are often filled with danger and excitement. They offer a unique environment where characters confront challenges, unearth hidden treasures, and meet unexpected allies or foes. My recent sketches draw inspiration not only from traditional dungeon layouts but also from the limitless possibilities hidden beneath the surface of a fantasy world.
For example, the idea of a forgotten temple buried deep in the earth, adorned with ancient carvings, sparked a vision for one of my sketches. Drawing from mythology and classic fantasy literature, each chamber I imagined comes with a story and a purpose. One chamber could be a once-bustling marketplace now laid to ruin, while another serves as a prisoner’s cell, complete with shackles and echoes of the past. This rich storytelling means that my sketches are not merely artistic representations; they serve as visual cues that enhance the narrative and engage players.
Designing the Dungeon Map
Designing a dungeon map is a meticulous process that finds a balance between creativity and practical design. Each room must serve its purpose while guiding players through exploration, combat, and puzzles.
In my sketches, I start on graph paper, plotting a rough layout to visualize how the chambers connect. For instance, in one dungeon, a warrior might battle goblins in a hidden alcove, while in another, a rogue could disarm traps placed at a crossroads. Once the basic structure is set, I transition to watercolor, beginning with lighter washes to establish the overall environment and mood of the dungeon.
I often engage in conceptual sketches—what I like to call “squash”—prior to committing to a single design. These sketches capture not just architectural elements but the feeling of the space, striking a balance between the foreboding atmosphere of a dungeon and its intricate beauty.

Techniques in Watercolor
Watercolor brings an element of unpredictability that I have come to love. Employing various brush techniques—like wet-on-wet for soft edges or wet-on-dry for sharp details—adds layers of depth to my sketches.
The first step in my watercolor process involves laying down a base wash that captures the general tone of the space. For a dungeon, this might be a gloomy gray for a shadowy cavern or earthy browns and greens for an underground forest. After the base is dry, I add layers, incorporating details like shadows and textures that breathe life into the map. The beauty of watercolor lies in its spontaneity, where unexpected brush strokes can create stunning effects.
In this process, I reflect on the stories I want to convey. Is this dungeon a place of ancient power, the ruins of a lost civilization, or perhaps the lair of a cunning monster? Each decision guides my color choices and design elements, creating a cohesive narrative that enchants players.
Adding Story Elements
While the artistic execution is vital, the stories woven into these sketches are equally important. Each room deserves its own history—whether it was once a wizard's laboratory or now serves as the den of hungry goblins.
As I sketch, I delve into the lore behind each section of the dungeon, adding layers of depth to the visuals. For instance, a treasure room may have been sealed for centuries, filled with dust and cobwebs, with hints of enchanted artifacts waiting to be discovered. These annotations invite players to explore further, leading to moments of excitement as they uncover relics and engage in crafted dialogues tied to each space.
By embracing this storytelling approach, I ensure that every detail in my watercolor sketches serves a purpose, sparking curiosity and prompting exploration.
Final Reflections
Crafting D&D dungeons through watercolor sketches has opened new avenues for creativity in both my gameplay and my art. The blend of storytelling and artistry enhances not just my work but enriches the overall experience for players at the table.
Through innovative concepts and exploration of different design techniques, I can bring these mystical underground realms to life, encouraging players to fully immerse themselves in the adventure. I hope that sharing my journey inspires fellow D&D enthusiasts and artists to unleash their imagination and embark on their own artistic quests.
Every dungeon is a gateway to countless adventures, just waiting to be explored. So, grab your brushes, gather your dice, and dive deep into the mysterious underground!
Stay creative, and may your next D&D session lead you to extraordinary depths!


I like this approach to mapping dungeons, maybe I would stop at the graph paper part, as I do not have much time. ☺️
