Detection

PerDC 14
StlDC 14 (to notice the fungus is reacting to your presence)
InitNone

The fungus grows in thick, velvety mats of deep purple. It is covered in translucent, teardrop-shaped bladders that shimmer with a pale violet luminescence whenever there is a sound nearby.

Standard Engagement

Trigger

The hazard is triggered when a creature moves within 10 feet of it or makes a loud noise (such as shouting or combat) within 30 feet.

Routine

None

Reset

The fungus regrows its memory-sacks every 24 hours.

Psychic Feedback

When triggered, the fungus releases a cacophony of stolen memories. Each creature within 15 feet must make a DC 14 Intelligence saving throw. On a failure, a creature takes 14 (4d6) psychic damage and is stunned until the start of its next turn as its own memories are violently played back to it. On a success, it takes half damage and is not stunned.

Dreadful Echo

If a creature fails the saving throw by 5 or more, it loses the memory of the last hour, making it impossible to remember how it entered the room or what it saw there.

Dampening Growth

Sound does not travel well near the fungus. All Wisdom (Perception) checks relying on hearing made within 30 feet are made with disadvantage.

Description

A dense patch of indigo fungus that absorbs sounds and memories, releasing them as a crushing psychic blast when disturbed.

Discovery

A creature can identify the fungus and its nature with a DC 14 Wisdom (Survival) or Intelligence (Nature) check.

Archival Lore

Legend says this fungus first grew in the ruins of a city where every citizen was sworn to a vow of silence. It feeds not on light, but on the vibration of secrets.
