Tomfoolery in Eberron
Blurgurbl Jelly is a disgusting substance with a deep, dark blue appearance and high viscosity. It is made of a few rather rare substances, and takes a skilled hands to craft correctly. Notably, it contains Murloc oil as it’s main ingredient.
Once a creature slathers this jelly over their body, they gain cold resist for 12 hours or until the jelly is washed off or removed. To completely cover a medium creature, you need a full 6oz jar.
Blubber said he got the 2 jars from a nomadic traveling murloc shaman.
