  • Ethereal Sight. The toili can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.
  • Incorporeal Movement. The toili 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.
  • Mournful Presence. Each time the swarm takes damage, any creature within 5 feet of it must make a DC 12 Wisdom saving throw. On a failed saving throw, the creature suffers the following effects until the end of its next turn: it has disadvantage on its attack rolls, it can’t take reactions, and its speed is halved.
  • Soul Absorption. The toili absorbs the soul of any Humanoid it kills. The victim’s soul is trapped in the toili for 24 hours, after which time it is fully absorbed and the person is incapable of being revived. If the toili dies before the soul is absorbed, the soul is released. While a soul is trapped in the toili, any magic that tries to restore the soul to life has a 50 percent chance of failing and being wasted.
  • Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Small humanoid. The swarm can’t regain hit points or gain temporary hit points.
  • Undead Nature. The toili doesn’t require air, food, drink, or sleep.


  • Tragic Touch. Melee Spell Attack: +4 to hit, reach 0 ft., one creature in the swarm’s space. Hit: 9 (2d6 + 2) necrotic damage, or 5 (1d6 + 2) necrotic damage if the swarm has half of its hit points or fewer. The target must succeed on a DC 12 Constitution saving throw or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.
  • Ethereal Passage. The toili enters the Ethereal Plane from the Material Plane, or vice versa. It is visible on the Material Plane while it is in the Border Ethereal, and vice versa, yet it can’t affect or be affected by anything on the other plane.
  • Ghostly Funeral (Recharge 5-6). Each creature in the swarm’s space must make a DC 12 Wisdom saving throw. On a failed saving throw, a creature takes 24 (7d6) psychic damage and is stunned until the end of its next turn. The effect ends on a creature if the swarm moves out of the creature’s space or if another creature within 5 feet of the swarm uses an action to make a DC 12 Strength check, pulling the affected creature out of the swarm on a successful check. On a successful saving throw, a creature takes half as much damage and suffers no other effects.


The toili appears as a ghostly funeral procession, complete with mourners, a casket, and a priest. The figures are translucent and ethereal, moving in slow procession as if following funeral rites. The casket is empty, and the mourners’ faces are veiled in sadness. The entire scene emits a melancholic aura, and the air feels heavy with sorrow when the toili is near.

Toili are often found in areas associated with death, such as graveyards, cemeteries, and locations where recent deaths have occurred. They manifest their ghostly funerals in these areas, often appearing near individuals whose deaths are imminent. Toili are known to appear at crossroads and intersections, places of transition between life and death.

Toili serve as harbingers of impending death, appearing as ghostly funeral processions that foreshadow the demise of individuals. Those who encounter a toili are often struck with a sense of foreboding and sadness, and it is believed that crossing paths with a toili is an ill omen that should be avoided at all costs.

The appearance of a toili is considered a grim premonition, a warning of the imminent demise of someone in the vicinity. Those who witness the ghostly procession are advised to stay away, as interacting with the toili or attempting to intervene in its activities can result in dire consequences, including injury or death.
