Detection

PerPassive Perception 14 notices the mist pulsing in time with a creature's heartbeat.
StlDC 14 (The mist is obvious, but its magical nature is hidden)
InitNone

A thick, waist-high fog the color of a fresh wound. It smells strongly of copper and ozone, and faint, whispering screams can be heard from within the swirling particles.

Standard Engagement

Trigger

A creature enters the area of the mist or starts its turn within it.

Routine

None

Reset

The mist is replenished by enchanted vents in the floor. If dispersed, it reforms completely after 1 hour.

Visions of the Spectral Betrayer

A creature that triggers the mist must succeed on a DC 14 Constitution saving throw. On a failure, the creature takes 2d10 psychic damage and becomes poisoned for 1 minute. While poisoned in this way, the creature perceives all allies as hostile, vengeful spirits. The creature must use its action to make a melee or ranged attack against the nearest ally it can see. The target can repeat the saving throw at the end of each of its turns, ending the effect on a success.

Copper Lungs

If a creature fails the saving throw by 5 or more, they are also blinded by a film of blood over their eyes until the end of their next turn.

Description

This heavy, crimson vapor consists of ancient blood held in a necrotic suspension. It clings to the ground and reacts to the heat of living bodies, swirling aggressively around anyone who enters its space.

Discovery

A DC 14 Intelligence (Investigation) check of the vault floor reveals that the many skeletons scattered about were killed by weapons typical of adventurers, such as notched swords and arrows, rather than vault defenses.

Archival Lore

Created by the lich-artificer Xal-Vash, this mist was designed to ensure that even if a team of thieves reached his inner sanctum, they would tear each other apart before touching his treasures.
