Brain of Confusion

The Brain of Confusion is an Expert mode accessory item from the Treasure Bag dropped by the Brain of Cthulhu. Upon taking damage with the Brain of Confusion equipped, it will appear to float into the air and nearby enemies may become confused for 3-5 seconds (longer if the player received more damage, shorter if they are further away). The chance of enemies becoming confused (assuming they are not immune) is 60%, +0.4% per point of damage.

Tips

 * Some people consider the Brain of Confusion to be a disappointment compared to its Corruption counterpart, the Worm Scarf, which reduces damage taken by 17%. Despite this, it can still shine in certain moments, such as during Invasions, or for preventing the player from being swarmed by pests such as Cave Bats and Bees.
 * The Brain of Cthulhu may not drop its Treasure Bag if you are fighting in a very small space (like where you hammered the Crimson Heart that spawned it). If you don't get a Treasure Bag after killing the Brain of Confusion, build a simple platform arena in the chasm above and fight it there.
