About Possession Beast System
Requiem Online's Possession Beast System is a unique feature that can endow characters with immense power and abilities to survive difficult situations or to speed up hunting. There are different kinds of Possession Beast, each with the own unique skills, that grow and develop along with the character. 

About Nightmare Monster
Even seasoned and strong Temperions, who no longer flinch at the sight of severed monster heads, will form a party at night to defend themselves against the heinous Nightmare Monsters that appear at night to ravage the world. The following information details when and where they appear and vanish, and the different kinds of Nightmare Monsters that Temperions will encounter. Please note that the times and hours detailed below apply to REQUIEM world time, which passes more quickly and is not synchronized with real world time.
