What is the cheat code for the Rain Totem in Stardew Valley?
If you're not above some mild cheating, go to Marnie, buy a chicken, name it (681). This is the item code for a Rain Totem. You can either keep the chicken or sell it immediately, either way you'll only get one Totem, so I don't consider this too much of a hack if you use it sparingly.
The crafting recipe becomes available at Foraging Level 9. One to three Rain Totems may also occasionally be found in treasure rooms in the Skull Cavern.
In Stardew Valley, the code [74] is the Item ID for a Prismatic Shard, a very rare and powerful gem, and using it in specific naming exploits (like naming your character, farm, or animal) can trigger the game to spawn these shards when the name is mentioned, essentially allowing for free items. This glitch works by entering the code in square brackets [] in a name field, giving players powerful items like Prismatic Shards or even Iridium Sprinklers early in the game.
The Rain Totem will change the weather for the following day to rain unless the following day is a festival or the 1st day of a season. (Spring 2-4 of Year 1 also cannot be changed by a Rain Totem.) The weather will always be "clear and sunny" for Festivals. It will never rain in Winter unless a Rain Totem is used.
Using a Rain Totem never has a chance to cause a storm unless used on a stormy day (which will make the next day stormy as well). Otherwise will only cause rain.
Unfortunately, players cannot make green rainfall from the skies in Stardew Valley. It's just a matter of waiting for Green Rain days and putting things in place. To be prepared, players can monitor the weather report daily on the TV in their home to see what tomorrow has in store.
Rain Totems spawn in the Jungle Zone, Coast Zone, Glacier Zone, and in the Coral and Sacred Ruins. They are found in groups around obstacles. Rain Totems are also found in the Toad Shrine.
Stardew Valley green rain is a random event you have no control over that will gives access to certain things like moss, fiber and seeds, It also grows Fiddlehead Ferns which drop mossy seeds that grow trees that only appear during green rain. You can also use them to complete the Chef's Bundle at the Community Centre.
Secret Note #19 in Stardew Valley is a treasure map leading to a hidden Solid Gold Lewis Statue behind Mayor Lewis's house, found by following a series of arrows from Jodi's blue house, moving in the indicated direction until hitting an obstacle, then changing direction as per the next arrow. The note shows Jodi's house (1 Willow Lane) and directions like right, up, down, left, leading to a spot in Lewis's backyard where you use a tool (like a pickaxe) to dig up the statue, a fun easter egg.
