Description

Dare to sit upon a throne that should never be claimed.

In the heart of a forgotten desert, a ruin drifts like a mirage—appearing without warning, swallowing all who enter, then vanishing without trace. Whispers speak of a bone-carved throne, a cursed monarch, and a seer who always arrives before the end.

Shifting Throne of the Bone King is a deadly one-shot dungeon built for brutal efficiency. Designed to run in a single session, this standalone adventure drops your party into a high-stakes encounter where every decision matters. Will your players destroy the Bone King and escape the cycle, or fall prey to its eternal curse?

This is the first release in the One Map Mayhem series — tightly designed one-shots built around a single, vivid map, each with a unique boss, branching outcomes, and brutal twists.

2024 D&D5e Compatible, recommended for 5th-level characters.

This adventure includes:

• 1 full-color tactical battle map (GM & player versions, with and without a grid)
• 3 interconnected encounter zones
• 1 terrifying undead boss: the Bone King
• 2 cursed magic items (sentient crown & necrotic scepter)
• 5 custom stat blocks
• Optional rules for claiming the throne and altering the curse

One map. One monster. One cursed throne. Mayhem awaits!
