Weapon (dagger), rare (requires attunement)
This magic dagger with a blade of pure obsidian becomes as light as a feather once one attunes to it. It is said an inky blackness trails from the tip of the blade with every movement.
You gain a +2 bonus to Attack and Damage Rolls made with this weapon, with or without attunement.
If attuned, when you hit with it, the target takes an extra 1d6 necrotic damage. When you hit an undead with this weapon, they are no longer considered resistant to necrotic damage if they were before.
Proficiency with a dagger allows you to add your proficiency bonus to the attack roll for any attack you make with it.
Notes: Damage: Necrotic, Bonus: Magic, Damage, Combat, Finesse, Light, Thrown
