The Amalgamated Brain is a craftable Hardmode accessory exclusive to Expert Mode. It grants an increase to all damage types, causes shade to rain down when the player is hit, and has a chance to inflict Confused on nearby enemies when the player is hit. The chance to inflict Confused and its duration both scale with the damage the player took.
- Shade rain deals magic damage and benefits from magic bonuses. However, its damage cannot be increased through any means.
- The shade rain has a base damage of 60.
