@JeremyECrawford Hi, I recently DMed for a WotC sponsored video series with Viva La Dirt League and in the newest episode I allowed Hold Person to work on a mummy and a skeleton. The comments are blowing up in debate over whether it should work or not. Does nothing hold undead?

Hold person works only on creatures that have the humanoid creature type. Undead is a different type.
Hold monster works on any type of creature, except undead.
These are two of the reasons people in D&D worlds value clerics and their Turn Undead ability. #DnD https://t.co/fTCm86G9wE

Hold undead holds undead. It exists all the way back to 2nd hence hold person does not effect undead as there is a whole spell for it. In short no charm spell effects undead unless specifically stated hence command does not work on a vampire. And why turn undead destroy undead and control undead exist as abilities in 2nd edition all the way till 5th removed only control. In hold person it specifically states it does not effect undead. Hence why hold undead doesn’t effect any living creature. Hold monster is for any non undead monster, hold undead even effects dracolichs, it should be the same level as hold person. Otherwise monsters like bone dogs, undead monsters would be immune as they would be undead. It’s not that complicated
