Bodysnatch (5e Spell)
From D&D Wiki
|Casting time:||1 action|
This spell allows the user to touch a corpse and turn it into a disguise. Once the disguise is worn, the wearer becomes functionally identical in appearance to how the deceased appeared in life, unless the corpse is older than 1 day at which point the disguise will show signs of decay and not hold up under inspection. The disguise can also only be worn by wearers of the same size class. After 24 hours, the disguise will return to being a corpse and be too worn out to be used as a disguise again.
At Higher Levels: For every spell slot level past 1st level, you can use this spell on a creature one size category or higher than you.
