The Umbrella is a Survival item that negates Sanity loss caused by the Rain while equipped. If playing as WX-78, the Umbrella will prevent damage caused by rain.
It requires 6 Twigs, 1 Pig Skin, and 2 Silk to craft and a Science Machine to prototype. The Umbrella can also be used as a melee weapon, but this is not recommended as it deals little damage and breaks after 20 uses. Otherwise, the Umbrella will never break no matter how often the player uses it.
