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 getting the Confused debuff, with the chance and duration increased by 0.4% per point of damage.

In, the player wielding it has a 1/6 chance of dodging an attack, and receives an increase of 20% critical strike chance for 4 seconds 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 ($\text{duration}_{max}$ )

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.
 * In the, the added chance to dodge nearly matches the percentage of damage the Worm Scarf prevents along with the extra critical bonus. This means that both accessories will, on average, prevent the same amount of damage but in a different way. This makes the Brain of Confusion significantly less disappointing and is arguably even better than the Worm Scarf, depending on the scenario. Often in Master Mode, taking damage in the first place can be extremely dangerous, so a chance to dodge can prove to be more useful in tight situations as taking 17% reduced damage from the Worm Scarf may still be too much.
 * The short term DPS increase from the critical hit chance increase after a successful dodge can allow the player to deal much more damage to enemies or bosses for a short period of time. Some could consider this to solidify the Brain of Confusion's place as the DPS version of the Worm Scarf.
 * However, the best of both worlds would be the use of both accessories at the same time, significantly increasing the player's chances of survival, while also improving DPS capability.
 * It has a 1/6 (16.67%) chance to dodge attacks, which is higher than Master Ninja Gear/Black belt's 1/10 (10%)
