  • Fiend Shroud. A fiend wholly within the swarm’s space is invisible. Incorporeal Movement. The swarm can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.
  • Life Sense. The swarm can only detect creatures other than constructs and undead with its blindsight ability. If blinded, it can’t detect anything other than these creatures within the range of its blindsight. Swarm. The swarm can occupy another creature’s space and vice versa. The swarm can’t regain hit points or gain temporary hit points.
  • Timeless Blood. The swarm roils with fiendish and mortal blood. A creature that starts its turn in the swarm is exposed to the timeless blood curse (page 123).


  • Claws. Melee Weapon Attack: +6 to hit, reach 0 ft., one non-fiend target in the swarm’s space. Hit: 21 (6d6) slashing damage and 7 (2d6) necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage it takes. The reduction lasts until the target finishes a long rest. The targets dies if this reduces its hit point maximum to 0.


This thin fog is filled with fanged faces and clawed fingers. The fog is the deep purple color of a bad bruise.

The spirits in a damned soul swarm are bodiless, but that doesn’t assuage their hunger for their lost mortality. Some damned soul swarms draw blood from wounded enemies, causing ribbons of blood to pour out from wounds. The spirits howl in frustration as they derive no real sustenance from this process, meaning they never even partly sate their hunger for their lost vitality. These damned soul swarms are a livid purple in color, like an angry bruise. This coloration fades if the swarm hasn’t feasted on blood within the past several days.
