I think I want to homebrew one into a pc with some form of major (minor) illusion. Looks/acts human, but takes double damage from bashing attacks. Has to stealth to pick up lost limbs to heal. And the rest of the party has no idea until one casts detect undead.

If you are looking for an illusion spell for this situation, you could go with Disguise Self or a magic item that mimic its effects, such as a Hat of Disguise. I think it's a very cool idea and I am curious to know what magic or effect you may homebrew to create such a creature. I would add that a Cleric's Channel divinity: Turn  Undead ability, even cast from an ally, could give it away, whether or not the caster knows the nature of your PC, as it targets "each undead that can see or hear you within 30 feet of you".

Lastly, I don't think there is a 5e spell cast "Detect Undead", but maybe you are referring to a Grave's Cleric ability or to a Ranger's Primeval Awareness.

I'm myself planning to play a tieffelin walock who uses the Mask of many faces Eldritch invocation to pass as a half-elf, because of the bad reputation of tieffelins (fantasy racism) and because he would himself hate his infernal legacy.

I would probably need to convince the DM to allow a 10-minute ritual that extends the duration of their at-will Disguise Self from one hour to one night of sleep, but would end when they move or take damage, so that if my character is ever woken up in the middle of the night he would have to either let his friends discover his nature, or spend one action to renew the spell. This, along with the fact that the "half-elf" mutters strange words every hour or so and doesn't ever let anyone touch him, would allow me to hint other players at the truth.

I like very much having secrets to other players, or at least to their PCs. I'm currently playing a walock (the one named Briken, indeed) who claims to be a wizard.

SPOOKY SCARY SK3LETONS

disagree, vulnerability is very powerful in 5e

Replace them with wights and tinker around with their abilities/equip.

Could you maybe like persuade them to let you sit on their pelvis if you are a small owlin lol

anything that can wear/use said item can attune to it, skeletons might even attune without command if they know it will help killing stuff.

I imagine the skeletons dying like the skeleton tortoises in Mario where the bones crumble

I think it should be immune to necrotic damage

Do you guys think they're better than zombies?

 100%. Zombie cons: ac 8, weak,minuses to almost all abilities,only strong in groups, not a lot of damage when attacking,poorly executed fight strats

Skeleton cons : vulnerable, not smart,only strong in groups

Do you guys think 1,923,125 of these is good for my party of 8 level 20s

 no add more. BTW i am running a fortress defense for a game and there are a ton of these guys

8 level 20s have a half chance against tiamat

hiiiiiiiiiiiiiiiiiiiiii

How did it work out for you? I'm playing a necromancer character right now & I'm planning on talking with my DM about it, but I'd like to know if it worked for someone else before I try my hand at it.

rattle me bones

thanks

can there be a skeleton made of gold? or like, wearing gold as armor or something?

Skelly Boneses!

POV the necromancer PC finds a recent battlefield (free equipment for skeletons) and sends in a swarm of insects or such.

Later on in campaign: Necromancer finds shape stone and wall of stone for building lairs/castles with to hold their piles of spare bones
