History
This spell was created by the mage Snilloc. He placed this spell in the tome The Collected Wisdom of Snilloc. Eventually the tome was stolen and this spell was copied and appeared throughout the Realms. This spell was also in the pamphlet Volo's Guide to All Things Magical published at the start of 1369 DR. This spell quickly passed into the ranks of the Zhentarim and most of their mages have access to this spell. The Red Wizards of Thay quite often place this spell on scrolls.
