The 混乱之脑 is an 专家模式 配饰 item from the 宝藏袋 dropped by the 克苏鲁之脑. Upon taking damage with the Brain of Confusion equipped, it will appear to float into the air and nearby enemies may become 困惑 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 免疫) is 60%, +0.4% per point of damage.
- The effect can be activated by any form of damage including damage taken by traps and thorn bushes.
- It is not affected by dye.
- Many people consider the Brain of Confusion to be a major disappointment, as opposed to its 腐化 counterpart, the 蠕虫围巾, 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 洞穴蝙蝠s.
