Detection

PerPassive Perception 14
StlDC 14 Wisdom (Perception) to notice the silver filaments
InitNone

Ethereal violet fungi that glow faintly in the dark, surrounded by a light haze of shimmering spores.

Standard Engagement

Trigger

A creature enters the area or starts its turn within 10 feet of the mycelium while making noise (including speech).

Routine

None

Reset

The fungi regrow and replenish their spores every 24 hours unless the soil is salted.

Spore Cloud

When triggered, the fungi release a burst of spores. Each creature within 10 feet must make a DC 13 Constitution saving throw, taking 10 (3d6) poison damage on a failed save, or half as much on a success. Creatures that fail the save are also Poisoned for 1 minute.

Echoing Voices

The dissonant hum intensifies into psychic screams. Each creature within 10 feet must succeed on a DC 13 Wisdom saving throw or take 7 (2d6) psychic damage and use its reaction to move 10 feet in a random direction away from the source.

Sympathetic Resonance

Casting a spell with a verbal component within 20 feet of the Whispering Mycelium triggers it immediately.

Description

A dense patch of pale violet mushrooms connected by shimmering, silver filaments that vibrate with a low, dissonant frequency.

Discovery

A DC 14 Wisdom (Perception) check allows a creature to hear a faint, headache-inducing hum before stepping into the hazard's range.

Archival Lore

Legend says these fungi grow where a telepath once died in agony, the soil absorbing their final, fractured thoughts.
