This magic weapon warns you of danger. While the weapon is on your person, you have advantage on initiative rolls. In addition, you and any of your companions within 30 feet of you can't be surprised, except when incapacitated by something other than nonmagical sleep. The weapon magically awakens you and your companions within range if any of you are sleeping naturally when combat begins.
Creatures that are Small or Tiny have disadvantage on attack rolls with heavy weapons. A heavy weapon's size and bulk make it too large for a Small or Tiny creature to use effectively.
This weapon requires two hands to use. This property is relevant only when you attack with the weapon, not when you simply hold it.
As long as this weapon is within your reach and you are attuned to it, you and allies within 30 feet of you gain the following benefits.

If you hit a creature with a melee attack roll using this weapon, you can make a melee attack roll with the weapon against a second creature within 5 feet of the first that is also within your reach. On a hit, the second creature takes the weapon's damage, but don't add your ability modifier to that damage unless that modifier is negative. You can make this extra attack only once per turn.
