Wight
6th Level Warrior Build
Great Undead Warriors, these creatures show a surprising amount of control over their own actions, although they are sometimes found in the company of mighty Necromancers, Vampires, or similar. They are warrior-kings buried with their full gear and regalia, and while they may be rotting and decrepit, their skill has not tarnished, unlike their armor.
Suggested Garb: Dark colors, skeletal or rotting face paint, stained or rusted armor, etc.
Basically, this is a case where your abilities already help you roleplay an undead creature pretty easily. True Grit? You’re coming back from the dead (again). Shake it Off? The dark power that courses through your rotting body allows you to ignore the petty magics of the living. Have fun. Ham it up.
