Umbral Blot (Blackball) (4e Creature)
From D&D Wiki
This is a conversion from 3rd Edition D&D. Some difficulty arises in design philosophy between the editions-- 4th edition does not like permanent effects, while 3rd edition loved them. But some inspiration can be taken from the 4e rust monster, where effects last until the end of the encounter. At epic level, however, players should have access to the Planar Portal ritual, so that will suffice for the equivalent of "End of the Encounter"... anything they lose can be recovered by Planar Travel of some sort.
For this conversion, I used Upper_Krust's 3e to 4e conversion guide, showing that a CR32 creature should be about a level 23 solo.
Umbral Blots, or Blackballs, are intelligent holes in reality that erase the existence of all they touch. The blot is described as "a hovering sphere of absolute void". Often, they are mistaken for Spheres of Annihilation, obeying beings capable of commanding such artifacts until they decide to turn on them.
Umbral Blot (Blackball)
DC 0-19 (failure): You don't know what this is.
DC 20-26 (failure): This is a Sphere of Annihilation, an artifact which will instantly destroy anything it touches. It can be controlled by anyone with sufficient willpower, that is to say, a sufficiently high Arcana check.
GM Note: The Umbral Blot can make an Insight Check to see if someone might believe this lie, and act accordingly.
DC 27: This is not a Sphere of Annihilation, but an Umbral Blot, or Blackball. For many, the distinction is academic, as they both destroy anything they touch. However, Umbral Blots are intelligent and malevolent. If you attempt to treat it like a Sphere of Annihilation and control it, it may choose to obey you until your guard is down, at which point it will destroy you utterly.
DC 37: It is said that Umbral Blots were created by the Old Gods- those that ruled prior to the gods of today- to be messengers or even assassins, and are credited with the downfall of their creators, destroying them completely.
Umbral Blots often pretend to obey Wizards, Sorcerers, and other Arcane magic users for a time, until they can best betray their former "master". Of course, it was ever only master in name only-- no one commands a Blackball.

The aspect of Nerull believes that the Umbral Blot is a Sphere of Annihilation under its command, and orders it to destroy the player's party of 4. A foolish party might attempt to wrest control from the Aspect of Nerull and command the Umbral Blot themselves. It might even obey them if it looks like a good opportunity to betray the Aspect. It will attempt to destroy the party afterwards, of course... or worse, destroy everything the party loves.
