Undeads can see in the dark up to 60 feet. Darkvision is black and white only, but it is otherwise like normal sight. Undeads can function just fine with no light at all.

Undead are undead rather than humanoids. This provides the undead with numerous undead traits:

- Immunity to all mind. affecting effects (Charms, Compulsions, Phantasms, Patterns and Morale Effects)

- Immunity to poison, sleep effects, paralysis, stunning, disease, exhaustion, and instant death effects.

- while positive energy hurts them (spells such as Cure Wounds will make radiant damage to undead).

- Negative energy heals undead, (When you take necrotic damage, you will regain hit points equal that necrotic damage)

- Undeads do not heal naturally. (You are unable to receive any normal treatment, such as rehabilitation or potion of healing)

- Immunity necrotic, bludgeoning, piercing, and slashing from nonmagical attacks but Vulnerability radiant.

- Armored. Your AC can't be less than 14, regardless of what kind of armor you're wearing.

-Toughened. Your maximum hit points score increases by 1, and it increases by 1 every time you gain a level.

- Not affected by raise dead and reincarnated spells or abilities. Resurrection and true resurrection can affect the undead. These spells return a destroyed undead to her undead life; the curse makes it virtually impossible to bring an undead back to life as the creature she was before she died. Only a wish or miracle can accomplish that.

- Undeads do not breathe, eat or sleep. Undead spellcasters still need 8 hours of uninterrupted rest before preparing their spells.

You are immortal and cannot die.
- Not at risk from death from massive damage. Unlike other undead, Undead is not destroyed when reduced to 0 hit points or less. Instead, at 0 hit points, an undead is disabled. She can perform only one move action or standard action each round but does not risk further damage from strenuous activity.

If damage would reduce you to 0 hit points but does not kill you outright you can instead choose to make a constitution saving throw. The DC = 5 + half the damage taken unless the damage is radiant in which case you automatically fail the saving throw. On a success, you drop to 1 hit point instead of falling unconscious.

The Beyond awakened undead regains (5 + Constitution modifier + level) hit points at the start of its turn. If the Beyond awakened undead takes radiant damage or damage from holy water, this trait doesn't function at the start of the next turn, The target's severed body members ( head, fingers, legs, tails, and so on)if any, are restored after 2 minutes, If you have the severed part and hold it to the stump, it will instantaneously cause the limb to knit to the stump. If you have the severed part and hold it to the stump, it will instantaneously cause the limb to knit to the stump.

undead Healing. In lieu of taking any other actions in a round you can elect to spend one Hit Die to heal yourself. You can do this as many times in a day as you have Hit Dice left. Once you've run out of Hit Dice you must take a long rest to regain the Hit Dice.

Undead's lack the morality they had in life, so they often forget simple things, such as the law, good and evil, right from wrong. Most undeads are Neutral Evil, with some being Chaotic Neutral.

Since the undead can look like any race, they are mostly humans and have the same size and weight as them. But that undead that are of other races uses the size category from that race. E.g. a halfling undead will not be medium size, but small. Though, lacking the usual traits from the halfling race.

Your base walking speed is 30 feet.

Any you knew in life. This will change depending on what race you were before you were turned.

You and the other undead have advantage on an attack roll, saving throws,to hit +2 and extra 1d4 necrotic damage. against a creature if at least one of the undead allies is within 10 feet of the creature and the ally isn't incapacitated. This ability can overlap.

You creating a burst of necrotic energy that ripples outward from you. Each creature you choose within 30 feet of you must succeed on a Constitution saving throw or take 8d6 necrotic damage + 2d6 force damage per hit die you possess or half as much damage on a successful one. If damage would reduce that creature hit points to 0, this creature turn to undead under my control.

Once you use this feature, you must finish a short or long rest before you can use it again.

 On your turn, you can use a bonus action to turn the creatures killed by you or your friendly creatures within 5 feet of you into undead under control.
