Monster Monday again. This time with a repurposed Invisible Stalker, an elemental of vengeance.
While some elementals are brought for benign reasons to the Realms of the Field, the Invisible Stalker is always brought for one purpose: to hunt and kill some quarry.
The invisible stalker is a limited form of air elemental, but has sacrificed some of its cousin’s offensive power (the whirlwind attack) for true invisibility, except for the exact moment it attacks. Even then, it is a DC 15 perception check to see the “thickening” of the air that occurs when the creature uses its melee attack.
It is the attack itself that is visible (and very audible!), however, and once it moves away from the target, it becomes invisible again.
Stalkers are not always summoned to evil intent, but they are always brought to the Realms of the Field for lethal intent. Unlike many other creatures, an Invisible Stalker will not stop attacking its target until it has reached more than double its wound maximum—it beats its target until the stalker is defeated or the foe is broken and dead on the ground.
