Weapon (dagger), very rare (requires attunement)

This blade-bladed dagger provides a +1 bonus to attack and damage rolls made when attacking with it.

Additionally, the dagger threatens a critical hit on a 19 or a 20 on the attack roll.

Any creature struck by this dark dagger must make a DC 15 Wisdom saving throw or be inflicted with the demoralized condition for 1 minute. Additional failures do not increase the condition but do extend the duration of the original effect. Additionally, if the target is currently suffering from the demoralized condition, the wielder regains a number of hit points equal to the Hit Die of the creature struck by the weapon.
