Staff, Rarity Varies (Requires Attunement by a Spellcaster)
This staff is made of polished, interlocking bones. Runes are carved along its length.
Ominous (Uncommon). A skull adorns the top of the staff.
While you hold the staff, you can cast Chill Touch from it, using your spell attack bonus. Additionally, you have Advantage on Charisma (Intimidation) checks made while holding the staff, and the staff’s eye sockets glow a disquieting green, shedding Dim Light in a 5-foot radius.
Chattering (Rare). Several skulls fused together adorn the top of the staff.
When a creature you can see within 30 feet of you makes an attack roll, you can take a Reaction to impose Disadvantage on that roll, as the skulls’ eyes glow green and their teeth chatter unnervingly.
Pulverizing (Very Rare).The entire staff is made of fused skulls.
While you hold the staff, you can take a Magic action to point the staff at a Humanoid you can see. That creature makes a DC 17 Constitution saving throw. On a failed save, the creature takes 10d8 Necrotic damage and has the Prone condition as it’s crushed from the inside. On a successful save, the creature takes half as much damage only. Once used, this property can’t be used again until the next dawn.
