Lamia Mask

Every piece rolls its own chance when a Lamia dies, so the outfit arrives in whatever order luck decides and you will usually be sitting on spares of one part while you wait on the last. Both color variants of the enemy hand out the same three pieces at the same odds, so there is no point tracking down a specific one. This is Hardmode gear, so there is no way to start collecting early.

• The mask changes your character's hairstyle instead of covering it up. Only a couple of other head pieces do that, the Hero's Hat and the Huntress's Wig.
• The chest piece differs by character. Female characters get fabric across the torso, male characters end up bare chested, which is why the wraps look like nothing at all on a Mannequin. The item is still on the display and can be taken back off.
• Worn together the three pieces read as a darker recolor of the creature they came off.

None of this is armor. All three go in the social slots, so wearing the look costs you nothing and your real gear keeps running underneath.
