As a Magic action, you can assume the identity of a Humanoid or a corpse of a Humanoid that you touch that has been dead for no longer than 24 hours. An illusion causes your appearance to perfectly match the target, including clothing, armor, weapons, and other belongings. If the target is a corpse, you resemble the Humanoid as it appeared in life. Additionally, the corpse, its blood, clothing, and other physical evidence of its death, become magically invisible for 8 hours.
To discern that you are disguised, a creature must take the Study action to inspect your appearance and succeed on an Intelligence (Investigation) check against your spell save DC.
Once you use this feature, you can't use it again until you finish a Short or Long Rest. You can also restore your use of it by expending a use of your ValdaSpire24 (no action required).
