Each month (eh, some months?), we’ll give you a new magic item to use in your 5e game. This month, we give you the deathspeaker spear.
Spear, rare (requires attunement)
You gain a +1 bonus to attack and damage rolls made with this magic weapon. When you roll a 20 with an attack roll with this weapon, you deal an extra +1d6 necrotic damage.
You can cast speak with dead by stabbing this spear through the chest of a corpse. The spell lasts for the duration or until you remove the spear. Additionally, while impaled by the spear, a corpse cannot lie, as if affected by a zone of truth spell (no save). You can use this ability once, and the spear regains this ability at sundown.
