Sergeant United Shield

The Sergeant United Shield is a Hardmode Boomerang. Only 1 can be thrown at a time. It automatically homes in on nearby enemies and will chain its attack to 4 additional enemies, however it will not hit an enemy more than once per throw. It is sold by the Traveling Merchant for.

Like the Brand of the Inferno, with any equipped shield (including the Sergeant United Shield when not thrown) and holding this Boomerang, right-clicking will cause your character to brace for the next attack. When timed correctly, just before taking a hit, the enemy's attack will be parried, dealing some damage to the attacker and granting the Striking Moment buff for the next five seconds. This allows your next melee attack to deal 500% of its damage. Alternatively, if the shield is held in place, 20 defense is temporarily gained; this lasts until the shield is once again lowered.

Its best modifier is Demonic, as it cannot get modifiers that affect speed or knockback.
