Your level 5 dungeon is broken because you're still building it like a level
1 dungeon — here's how to fix mid-level B/X and OSE design for 2026.
🔥 JOIN THE MINIONS: youtube.com/@TenkarsTavern/join
Between character levels 4 and 8, the math of B/X shifts hard, and most DMs never update their dungeon layouts to match. This video breaks down how to redesign your dungeons for mid-level play: turning isolated rooms into tactical loops, building factions and political stakes instead of static monster encounters, recalibrating traps for strategic complication instead of lethal damage, and designing around your players' new magic instead of fighting it with DM fiat.
The Tavern Rules: We’re here for B/X and OSR gaming. I use AI as a tool to help organize and format my notes, but every ruling and opinion is 100% Tenkar. Keep it civil, keep it old-school, or the bouncer will show you the door.
