Heartcleaver

Weapon (glaive), artifact, requires attunement

This worn and gored glaive was the weapon of the late Baphomet. You gain a +4 bonus to attack and damage rolls made with this magic weapon, which deals 3d10 force damage instead of its normal damage.

Whenever a creature is struck with Heartcleaver, you can choose to end one magical effect applied to that creature, as if dispel magic was cast at 9th level. If you don't, the target has disadvantage on its next saving throw involving Intelligence, Wisdom, or Charisma. (does not stack)

Charge. Whenever you move 20 feet in a straight line towards your target and then immediately hit a creature with an attack using this weapon, it takes an additional 5d10 force damage. Choose to either send the creature down or away. If you choose down, the target must succeed on a strength saving throw with DC equal to your strength score or be knocked prone. If you choose away, the creature is knocked up to 60ft backwards.

Heartcleaver has the following artifact properties:

• While attuned to the artifact, you can't be displaced, pulled, or pushed unwillingly.
• While attuned to the artifact, your Strength score increases to 20, or increases by 2 if it is already at 20 or above.
• While attuned to the artifact, your sense of direction is nonexistent. Unless you are following another creature, roll randomly whenever you would take one path out of multiple.
• While attuned to the artifact, whenever you fall below half of your maximum hit points, you can no longer tell friend from foe. On a turn that you intend to make an attack with this weapon, roll randomly between all targets within movement range. If one or more creatures is already within melee range, choose only between those creatures instead.
