Shadow Drinker

Alter: This wicked dagger can absorb the shadows cast by your enemies. You gain a +1 bonus to attack and damage rolls made with this weapon. When you hit a Small or larger hostile creature with a melee attack using this dagger, you can choose to absorb that creature's shadow as part of the attack. When you do, that creature no longer casts a shadow, and the dagger becomes shrouded in a dark haze that extends to you while you hold the dagger. While this haze is also surrounding you, you are invisible in areas of dim light and darkness.

The dark haze surrounds the dagger for 10 minutes or until you end it as a bonus action. The haze ends early after you attack or cast a spell. If a creature is hit by the dagger while it's shrouded in this haze, the creature takes an extra 1d6 psychic damage from the attack. This bonus damage increases to 2d6 if the creature hit by the dagger is also missing its shadow. Once the haze ends, the shadow immediately returns to the creature from whom it was taken.

You can only have 1 shadow absorbed in this way at a time. Once you steal a creature's shadow, you can't steal that same creature's shadow, you can't steal that same creature's shadow again until the following dusk.

Attunement: yes, cursed
Cursed: You have vulnerability to radiant damage while you've absorbed a shadow.
Rarity: Very Rare
