Blackstaff (spell)

Blackstaff was a spell applied to a staff or quarterstaff that enhanced its combat effectiveness, and gave it the ability to dispel magic or cause a spellcaster it struck to lose a prepared spell.

This spell was created by Khelben "Blackstaff" Arunsun and was part of the reason why his common appellation was Blackstaff, as he carried a staff of power that had this spell cast on it with permanency. The blackstaff spell was found in Laeral's Libram, a spellbook written by the wizard Laeral Silverhand. Laeral lost the spellbook sometime during her madness induced by the Crown of Horns, and it was not been seen since.

Khelben only shared this spell with those he trusted implicitly. However, by 1373 DR, the spell blackstaff was known and in use across the Realms.
