The Cloak of the Desert King is a Hardmodesummon weapon. It spawns a killer bunny that chases after enemies to attack. Like other minions, the summoned Killer Bunny is invincible and follows the player for an unlimited amount of time, unless the player dies or summons a replacement minion.
Its best modifier is Ruthless. The Mythical modifier provides the widest array of stats bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, Minions cannot deal critical hits. The only significant advantage a Mythical Cloak of the Desert King has over a Ruthless one is knockback.
