A flail made of titanbone, polished to a silvered sheen and edged in gold. The flail's head is a four sided mass, each side carved with the face of a man in ecstasy, agony, terror, or love, whose eyes are pools of molten light and within whose opened maws jut a tongue of razor-sharp metal. The silver chain seems to extend or retract at will. The weapon is impossibly heavy for those unattuned to it, but easily wielded by those who are.
You have a +1 bonus to attack and damage rolls made with this magic weapon. On a hit, you deal an additional 1d8 radiant damage, or 2d8 against Fiends or Undead.
Retractable Chain. This weapon gains the thrown property, with a range of 20 feet. You maintain your hold on the item when thrown, and the chain retracts back to normal length at will, quickly enough for the Extra Attack feature.
Bones of the Earth. When attuned to this weapon, you have advantage against any attempts to disarm you of it regardless of origin. If a disarm attempt does not permit you to save against it, you are now able to do so at the discretion of the GM.
Proficiency with a Flail allows you to add your proficiency bonus to the attack roll for any attack you make with it.
This weapon has the following mastery property. To use this property, you must have a feature that lets you use it.
Sap. If you hit a creature with this weapon, that creature has Disadvantage on its next attack roll before the start of your next turn.
