Flaying Dagger (5e Equipment)

Weapon (dagger), rare

You have a +1 bonus to attack and damage rolls made with this magic weapon.
This dagger has the flay spell prepared on it, as if by a spellcaster with a spell save DC of 15. The enchantment does not fade after 24 hours, but once the enchantment is activated and it runs its course, this item loses this additional property.
