Clubs are simple, blunt melee weapons wielded in one hand that deal 1d4 bludgeoning damage on a hit and have the Impact and Light properties.

Properties

Impact
This weapon deals double damage to objects and structures.

Light
When you take the Attack action and attack with a Light melee weapon that you’re holding in one hand, you can use a bonus action to attack with a different Light melee weapon that you’re holding in the other hand. You don’t add your ability modifier to the damage of the bonus attack, unless that modifier is negative. If either weapon also has the Thrown property, you can throw the weapon instead of making a melee attack with it.

Superior Strike

Reeling Blow.
You unleash the full force of your strength and size in a weighty strike. Make an attack roll against a creature within your reach. On a hit, the target suffers the attack’s normal effects and takes extra damage equal to your proficiency bonus. In addition, until the end of its next turn, the creature has disadvantage on all attack rolls, and on ability checks and saving throws that use Dexterity or Intelligence, and it can’t take reactions. In addition, if this attack causes a creature to make a Constitution saving throw to maintain its concentration, the creature has disadvantage on the saving throw.
