Primeferno fur catches on fire when they are angry, blazing with the heat of their rage. Explorers in Primeferno territory are advised to keep watch for fire in the branches above them, as it's often the only warning of an impending attack.

To intimidate attackers, it stretches the fire on its tail to make itself appear bigger. When it becomes furious, its blood circulation becomes more robust, and its muscles are made stronger.
