We are beginning a Curse of Strahd Campaign and one of my players wants to make a Skeleton Necromancer. Since there's no official Skeleton Race, I created this from the Monster Manual entry on Skeletons, while also throwing in some extra abilities from other creatures and my own crazed ramblings in an attempt to make up for the common vulnerability.
Skeletons
Ability Score Increase. Your Constitution score increases by 2, and your Dexterity score increases by 1.
Size. Skeletons match the height, but are half the weight of humans. Your size is Medium.
Speed. Your base walking speed is 30 feet.
Darkvision. Thanks to your undead nature, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.
Body Construction. Because of your relentless undead fortitude your body is capable of detatching and reattaching limbs. After a long rest you can choose one of the following abilities:
Detach Hand. Your dominant hand falls to the ground and becomes a Crawling Claw (Monster Manual pg. 44). You can use your action to control the hand. You can use the hand to manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. You can move the hand up to 30 feet each time you use it. The hand can't activate magical items, or carry more than 10 pounds. If the hand moves more than 60ft from you or is reduced to 0 hit-points, the hand becomes inert and cannot move and must be reattached to your body. While your hand is detached in this way, you cannot use two-handed weapons, any attacks your body makes are made at disadvantage and you have disadvantage on casting spells that require a somatic component.
Detach Head. Your head begins to hover off your body and float independently, your head gains a fly speed equal to your movement speed. Your body can still move and acts under your command but is considered Blinded and cannot speak until the head returns. The head in incapable of moving out of line of sight from your body and can only cast spells that only require a verbal component.
Detach Arm. Your non-dominant arm falls off and becomes inert, you or any creature can pick up the arm and use it as a bludgeoning weapon, the arm has the same statistics as a Club, any damage the arm takes while it is detached in this manner is automatically healed when the limb returns. While your arm is detached in this way, you cannot use two-handed weapons and you have disadvantage on spells that require a somatic component.
Attach Extra Bones. The necromantic energy that holds your body together becomes briefly more powerful. If you find a corpse, inert skeleton or kill a humanoid creature you can spend an action to magically summon the dead creature's bones to overlap your own body. You double your weight, gain temporary hit points equal to your Constitution score and a bonus to AC equal to half your proficiency bonus rounded down.
All abilities last for up to 1 minute at which point the limb will take the most direct path back to the body or the extra bones will fall inert to the ground, but you can end it early by reattaching said limb or dropping the bones (which does not require an action). Once you use your chosen ability, you cannot use it again until to take a short or long rest. You can choose an additional ability per day at levels 5, 10, 15 and 20, this could be a different ability or the same ability for an additional time each day.
False Appearance. While you remain motionless, you are indistinguishable from a pile of bones.
Necrotic Constitution. You have resistance to necrotic damage, and you have immunity to poison damage, the exhaustion condition and the poisoned condition. You also have vulnerability to bludgeoning damage.
Undead Nature. You skirt the line between life and death, you count as both humanoid and undead when it comes to spell effects and abilities. You can’t and don't need to eat, drink, or breathe.
Languages. You can speak, read and write common and one other language of your choice.
The vulnerability was actually requested by the player so I'd like to keep that if possible, the other abilities such as Body Construction, False appearance and the other elements of Necrotic Constitution where added as a way to make up for the vulnerability to a very common damage type.
If I need to be more specific about "Balanced"
- Do the other abilities make up for Vulnerability to Bludgeoning damage or have I gone over/under board?
- Do the Body Construction abilities make sense or should they be reworded or removed?
- A very notable disability of the skeleton is its inability to talk, should I include this as an ability (which would also mean they are incapable of casting verbal spells)?
- And most importantly, does playing as a skeleton (or any undead creature) in Curse of Strahd specifically, have any inherent unfair advantages/disadvantages?
