Created by a long-since forgotten mage (though some in Waterdeep insist it was once known as Hilather's Blacksphere), blacksphere is the core spell to the rare magical beads of force and the spell effects are nearly identical. When cast, a burst of black force erupts at the caster's desired focal point, causing 1d4 points of damage per level of the caster to all creatures within the area of effect (maximum 10d4 points of damage).
If creatures fail their saving throws vs. spell, they are also trapped within a 10-foot radius blacksphere for the duration of the spell; victims cannot escape the sphere by any means less than those used to destroy walls of force.
Successful saving throws allow creatures to escape being trapped in a blacksphere, though they still take the full damage from the initial force burst.
The material components of the spell are a small piece of charcoal and a small piece of onyx.
