The Breathless Bloom
The Breathless Bloom is a living carpet of dungeon mold that releases a shimmering cloud of spores when disturbed. The cloud does not kill quickly. Instead, it steals breath, blurs judgment, and makes familiar passages appear to twist into impossible shapes. The hazard is most dangerous when adventurers hurry, fight, or use open flame without thinking.
The Breathless Bloom
Defenses
Detection
“A carpet of pale blue mold coats the dungeon floor, walls, and scattered bones. It glows faintly whenever living creatures draw near. Thin threads rise from it like frost, trembling in an unseen breeze.”
Standard Engagement
A creature steps onto the colony, disturbs its roots, breaks nearby bones, or creates a strong burst of heat, wind, or flame.
The bloom remains still until disturbed. When triggered, it releases a dense cloud of glowing spores, then slowly creeps toward warm bodies while the cloud lingers.
The cloud settles after a few minutes. The colony becomes dormant again once the area is still, but it reactivates if disturbed.
When the Breathless Bloom is triggered, everyone in the infested area must Defy Danger with CON. On a success, they hold their breath or shield themselves and avoid the worst effects. On a partial success, they choose one: cough loudly and draw attention, lose their next opportunity, or suffer 1d6 damage. On a failure, they inhale the spores and become confused, coughing, and vulnerable until they leave the cloud or receive appropriate aid.
A creature that fails its Defy Danger sees false doors, moving walls, and phantom companions. Until it escapes the area or receives treatment, the GM may offer dangerous misdirections, separate it from the group, or make its next move put someone at risk.
The cloud fills the room or passage around the colony and lingers for several breaths. Anyone who stays inside must Defy Danger with CON again when they take a significant action or when the GM makes a move.
Open flame can clear the mold, but careless fire may ignite old debris, consume oxygen in a narrow passage, or attract dungeon inhabitants. Ask the players what they are risking before resolving the action.
