The Bloody Worm Scarf is a craftable Hardmode, Expert Mode-exclusive accessory that provides a 10% increase to damage reduction and increases melee damage and speed by 10%. This accessory can be considered the Crimson counterpart to the Amalgamated Brain, even though they both can be crafted regardless of the world evil.
- If the player lives in a crimson world, defeating the Brain of Cthulhu will make the Dryad sell the Worm Scarf.
- If the player lives in a corruption world, defeating the Hive Mind will make the Dryad sell the Bloody Worm Tooth.
- The damage reduction also stacks with the Worm Scarf.
- While the Amalgamated Brain is geared towards all users, the Bloody Worm Scarf is geared primarily towards melee users, as it increases damage for melee weapons.
