Bloody Handprints (Haunt) (5e Trap)
From D&D Wiki
Bloody handprints slowly appear on a surface, one by one. Are they leading you...and if they are, do you really want to find out...?
Targets: Anyone who touches the bloody prints.
Religion or Arcana DC 12 Skill Check: A murder or other violent death lingers as bloody marks that harm any creature touching the surface on which they appear. They can sometimes also signal where the crime happened, or a hidden secret.
Resets: Every 24 hours.
Effect: Anyone touching the surface takes 1d6 acid damage.
The bloody handprints vanish if the surface is thoroughly cleaned and scrubbed with holy water.
