Shattered Lineage

The sad reality of necromancy magic is not everything can be repaired, a shattered is a prime example of that. Formed when necromancers attempted to repair the bodies of long gone shatterborn they are a race cursed to fragmentation for the rest of their wretched days.
Age - Your age of maturity is based off your original race. You are functionally immortal though Shattered rarely live more than a few years after reanimation.
Evershifting-Fragments - Whenever you take an action, bonus action, or reaction roll a d20 and add your proficiency bonus. (You do not add a stat bonus to this save unless specified by a feature outside this race). Rolling a total below a 12 is a fail. If you fail the action is wasted as your mind struggles to string together the pieces needed complete the action. Additionally you have disadvantage on all concentration checks
Reconstructed - You take half damage from all sources (does not stack with resistance) and your max HP is doubled (doubling is applied after all additional hp, so calculate your total max HP with all feats and class features and etc before doubling it.)
Language - You speak common and one language your reanimator spoke.
