The ultimate among the Beast-type monsters, this creature combines extremely high stats and a Lv. 3 Stored Attack, Killing Step, with the physical immunity that was present in its predecessor, the Night Stalker, making it a dangerous foe. It can also raise its stats with its Howling skill, its normal attack has a high critical hit rate, and its Mist Breath attack can cause Darkness to everyone in the party. Always keep your eyes open for whenever it tries using Killing Step so you can guard your Reyvateil effectively, and try to finish the battle as fast as possible.
