Actions

Life Drain. Melee Spell Attack: +4 to hit, reach 5 ft., one creature. Hit: 9 (2d6 + 2) necrotic damage. The target must succeed on a DC 11 Constitution saving throw or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the creature finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.   Etherealness. The specterling enters the Ethereal Plane from the Material Plane, or vice versa. It is visible on the Material Plane while it is in the Border Ethereal, and vice versa, yet it can't affect or be affected by anything on the other plane.

Suggested Environments

The Specterling is often found haunting ancient crypts, forgotten graveyards, or eerie ruins where the boundary between the Material Plane and the Ethereal Plane is thin. It thrives in places marked by death, sorrow, and the lingering echoes of past tragedies. Its presence is a testament to the darkness that lingers in these desolate and haunted locations.
