Turn Immunity. The animated will is immune to effects that turn undead.

Undead Nature. The animated will doesn’t require air, food, drink, or sleep.

Corpse Walking. The animated will cannot rest or regain HP through traditional means. It has disadvantage on persuasion checks and advantage on intimidation checks.

Wear and Tear. Accumulated damage slowly breaks down the animated will's corpse.  For all non-psychic damage dealt to the corpse, its max HP is reduced by half the amount of damage received (rounded down).  This reduced HP can be restored by receiving either a lesser restoration or greater restoration within 1 hour of receiving the damage, otherwise it becomes permanent and irreversible by any means. 

Critical Injuries.  The animated will's corpse is particularly susceptible to critical injuries.  If the animated will receive a critical strike (not from a spell), the attacker rolls an additional time (same roll and modifiers as for the original attack) and, on a hit, they sever one of the will's limbs or head (randomly).  This extra roll does no additional damage and causes no other effects.

Falling Apart. When the animated will loses its head or a limb, its max HP is reduced by 1/5, 1/4, 1/3, 1/2, or all, according to the number of remaining Limbs and Head, calculated as 1/(1+H+L).  The head or limb can be reattached, and the associated reduced HP can be restored, by receiving greater restoration within 1 hour of the loss, otherwise they become permanent and irreversible by any means. This restoration would also restore any max HP lost to Wear and Tear within the last hour. 

Unending Will. By concentrating for ten minutes, the animated will rebinds its soul to its corpse - damaging the corpse in the process - and gains the following effects: max HP permanently and irreversibly reduced by 2; restore full use of any racial, class, or other features normally restored upon resting; and restore HP up to half of your current max HP. This feature is used automatically after 1 hour if the animated will has 0 HP while still having non-zero max HP.

Force of Will. The animated will overcomes physical limitations through sheer force of will. It can cast spells without verbal or somatic components and gains a 20-foot fly (hover) speed, 20 feet of blindsight, and 120 feet of Telepathy.

Bound Soul. The animated will is immune to traditional resurrection effects other than a wish spell, which would restore the original creature to life.

Actions

The animated will has access to all actions, bonus actions, and features it had in life. Features from its life that could restore HP can no longer heal the animated will.
