Incorporeal Movement. The specter can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.
Sunlight Sensitivity. While in sunlight, the specter has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
Life Drain. Melee Spell Attack: +4 to hit, reach 5 ft., one creature. Hit:10 (3d6) necrotic damage. The target must succeed on a DC 10 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.
A specter is the angry, unfettered spirit of a humanoid that has been prevented from passing to the afterlife. Specters no longer possess connections to who or what they were, yet are condemned to walk the world forever. Some are spawned when dark magic or the touch of a wraith rips a soul from a living body.
