Bardan ruqad

Bardan ruqad, which translated in Midani as "cold sleep", was a rare poison.  

Properties
Bardan ruqad was a strong poison capable of instantly paralyzing the victim. Victims under the poison's effect remained completely inert for up to ten minutes. They were completely aware of what was happening to them during this time, after which they fell into a deep slumber that lasted several hours. This poison did not cause any physical harm in the traditional sense.

Bardan ruqad even worked against all forms of undead, though they were slightly resistant to its effects initially taking root.

Applications
Though rarely encountered outside of their use of the poison, tasked messenger genies often applied bardan ruqad to their darts and daggers. The messenger genies used this attacked dangerous targets from a distance when delivering messages to them, allowing them to paralyze the target and safely deliver the message and escape before the target could retaliate.
