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, nearby enemies have 60% chance of causing Confused debuff, with the chance and duration increased by 0.4% per point of damage.

In, the player wielding it has a chance of dodging an attack, and receives an increase of 20% critical strike chance if successful.

Duration
The debuff duration is determined randomly, and the bounds depend on the amount of damage taken:
 * $$\text{duration}_{min} = \left( 90 + \left \lfloor \frac{dmg}{3} \right \rfloor \right) / 60$$, in seconds
 * $$\text{duration}_{max} = \left( 300 + \left \lfloor \frac{dmg}{2} \right \rfloor \right) / 60$$, in seconds
 * Examples:
 * {|class="terraria lined align-center"

! scope=row style="text-align:left;" | Damage taken ($dmg$ ) ! scope=row style="text-align:left;" | Minimum duration ($\text{duration}_{min}$ ) ! scope=row style="text-align:left;" | Maximum duration ($\text{duration}_{max}$ )
 * 1
 * 50
 * 100
 * 300
 * 1.5 seconds
 * 1.77 seconds
 * 2.05 seconds
 * 3.17 seconds
 * 5 seconds
 * 5.42 seconds
 * 5.83 seconds
 * 7.5 seconds
 * }

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 events, or for preventing the player from being swarmed by enemies such as Cave Bats.
