@JeremyECrawford The spell Summon Demon's material component is blood from a recently killed humaniod. If that humaniod is revived would the spell end, a circle of the blood no longer grant protection or would it the person still be considered killed in the last 24 hours.

If someone is killed and then revived, being revived doesn't change the fact that they were killed. #DnD https://t.co/bq0u37lq2M
