Potion of magic resistance

A Potion of magic resistance was a potion that provided resistance against magical effects.

Description
The potion was prepared in flasks. Normally, such a flask contained enough content for four usages.

Powers
The potion provided the imbiber resistance against magic for two to eight minutes. No inherent resistance against magic on the imbiber's side was needed to benefit from it. If the imbiber had a natural resistance against magic, that resistance was replaced with the one provided by the potion. The strength of the granted resistance fluctuated from dose to dose. Multiple consumption of the potion had no effect except for a slight tingling of the nerves, which also happened when the potion was effective. At least not without leaving a two to eight minutes gap between consuming two doses of it.

History
Drow had an inborn resistance against magic. While this resistance was strong in the case of adults, infants' and newborns' was not only weak but also not stable until youth age. Originally, drow alchemists invented the potion of magic resistance long before the 14 century DR to protect children from the additional magical danger they were exposed to, but use of it spread also for combat purposes.
