The caster makes a ranged touch attack against a foe, launching a bolt of cold darkness from his left hand. The bolt deals 1d8 points of damage per two caster levels (maximum 5d8). Half the damage is cold, and the other has no specific type. When struck, the foe must also succeed on a Fortitude save or be stunned for 1 round, overwhelmed by the evil charge of the dreadbolt.
Source: Lords of Madness, page 210. This spell was originally named darkbolt which conflicted with the same-named spell published later in the Spell Compendium on page 58. The latter version is considerably more powerful and restricted to the Darkness domain, so it was decided to rename the more obscure Lords of Madness version.
