What battlemap themes should every DM own?

The core set is forest, dungeon and cave, town and city, tavern and interior, coast and water, desert, snow, and ruins. Those cover the overwhelming majority of encounters in a typical campaign. From there, add themed sets your campaign actually visits: infernal, planar, sci-fi or underdark, rather than owning everything for its own sake.

How many variants of each map theme do I need?

At least a few of each common theme, so your forests, taverns and dungeons don't all look identical. Reusing one tavern map for every inn breaks immersion fast. A handful of variants per theme lets you match the map to the specific place and keeps repeat locations feeling distinct across a campaign.

What's the most-used battlemap theme?

Forest, dungeon and tavern maps see the most table time in most campaigns, because parties travel through wilderness, delve dungeons and keep returning to inns. Town and city maps are close behind. Those four themes alone will carry a large share of your encounters, so prioritise depth there.

Do I need niche themes like infernal or sci-fi?

Only if your campaign goes there. Niche themes, infernal, planar, cyberpunk, underdark, are worth owning when a specific campaign visits them, and unnecessary otherwise. A broad mega bundle is the efficient way to have them on hand just in case, without buying each niche pack separately.

Where can I get battlemaps for every theme?

MakeMythic on Etsy sells themed battlemap packs for individual biomes, plus a 250,000+ RPG battlemap mega bundle that spans every theme in this guide, high resolution and gridless for Roll20, Foundry or print.

The best D&D battlemap themes, biome by biome

TL;DR: Prioritise the themes your party actually uses, forest, dungeon, town, tavern, coast, desert, snow and ruins, and own several variants of each so repeat locations stay distinct. Add niche themes (infernal, sci-fi, underdark) only when a campaign visits them. A broad mega bundle is the efficient way to cover the lot.

Not all battlemap themes pull their weight equally. Some see table time almost every session; others sit unused unless a campaign takes a specific turn. If you’re building a map library deliberately rather than hoarding everything, it helps to know which themes earn their place, and how much depth each one needs. Here’s the biome-by-biome breakdown.

The core themes you’ll use constantly

A handful of themes carry the bulk of any campaign, and these are where you want real depth.

Forest and wilderness. Parties travel, and travel means woods, clearings, trails and riverbanks. Forest maps are among the most-used you’ll own, so hold several: dense old-growth, open glade, forest road, riverside.

Dungeon and cave. The genre’s namesake. You’ll want corridors, chambers, natural caverns and worked stone, in enough variety that your dungeons don’t feel like the same tileset every time.

Town and city. Streets, markets, alleys and plazas for the urban encounters and chases that break out whenever the party hits civilisation. Vertical, cover-rich city maps unlock some of the best fights in the game.

Tavern and interior. The inn is where campaigns begin, regroup and scheme. A range of taverns, from grubby dockside dive to warm coaching inn, plus their upper floors, keeps your hubs from blurring together.

The strong supporting cast

Below the core four, a second tier of themes comes up often enough to own properly.

Coast and water. Docks, beaches, harbours, ships and open water, for naval combat, boarding actions and seaside towns. A whole sub-genre of encounters lives here.

Desert. Dunes, oases, ruined temples and canyon passes, for arid campaigns and the classic tomb-in-the-sands adventure.

Snow and ice. Frozen passes, tundra, ice caves and winter towns, essential for northern campaigns and seasonal one-shots.

Ruins. Crumbling keeps, overgrown temples and broken monuments, endlessly useful because a ruin fits almost any biome and instantly implies history.

The niche themes, worth it only when you go there

The last tier is powerful but situational. Own these when a campaign calls for them, and don’t worry about them otherwise.

Infernal and planar. Volcanic hellscapes, demon-haunted wastes and otherworldly realms, indispensable for a campaign like Descent into Avernus, irrelevant for a grounded low-fantasy game.

Underdark. Fungal caverns, drow cities and lightless depths, for the campaigns that go down and stay down.

Sci-fi, cyberpunk and steampunk. Magitek streets, skydocks and clockwork interiors, for Spelljammer, Eberron and any world where the magic looks like technology.

These are the themes to reach for a dedicated pack only when the story needs them, or to have waiting in a broad bundle just in case.

How many variants per theme?

The rule of thumb: at least a few of every common theme, more of the ones you use most. The failure mode is reusing one tavern or one forest for every occurrence, which quietly tells your players the world is made of copies. A handful of variants per theme lets you match the specific place, this tavern, this stretch of woods, and keeps recurring location types feeling fresh across a long campaign.

The efficient way to cover it all

You can assemble this theme by theme with individual packs, and dedicated packs are great when you want deep coverage of one biome. But the efficient way to hold the whole spread, core, supporting and niche, is a single broad bundle.

The 250,000+ RPG Battlemaps Mega Bundle (~~£30~~ £9) spans every theme in this guide, with the variety to keep repeat locations distinct, high resolution and gridless for Roll20, Foundry or print. It’s the one-purchase route to having the right map for wherever your party actually goes, without deciding in advance which biomes your campaign will visit.
