Sing a Song of Blackbirds
A round bottle filled with a cold, blue mist.
Blue Fire is exactly the same as alchemist’s fire, but does cold damage instead of fire damage.
This strange concoction is made by Merna Brimblebrisket. How she came to know how to craft the stuff is a mystery. The bottle is round, stoppered with wax and filled with a light blue mist. Frost can be seen tracing its way across the interior of the bottle.
