You gain a +1 bonus to attack and damage rolls made with this magic weapon.
When you hit an undead creature with an attack using this weapon, the attack deals an extra 1d8 damage of the weapon's type, and the creature has disadvantage on saving throws against effects that turn undead until the start of your next turn.
You have Disadvantage on attack rolls with a Heavy weapon if it's a Melee weapon and your Strength score isn't at least 13 or if it's a Ranged weapon and your Dexterity score isn't at least 13.
A Two-Handed weapon requires two hands when you attack with it.
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.
