Revision 1

Overview

Mirthshroom Soup is a cooking recipe in Starsand Island that turns foraged mushrooms into one of the most strategically valuable dishes in the game. While its stamina recovery is modest at 45 points, the real draw is its Creamy Seeds buff, which gives players a chance to receive regular and immortal seeds every time they harvest a crop. This makes Mirthshroom Soup an essential tool for anyone working toward a self-sustaining farm built on Everlasting Seeds.

The recipe requires just two Mirthshrooms, a common mushroom found throughout the Moonlit Forest. Since Mirthshrooms can be gathered for free during exploration or grown cheaply on your farm, the dish costs almost nothing to produce. Players frequently describe it as "basically free to make," which is part of what makes it such an appealing everyday food choice.

Recipe Details

At just 24 seconds per batch, Mirthshroom Soup is one of the fastest recipes in the game. You can prepare a full stack of five soups in about two minutes, giving you the maximum buff before heading out to harvest your fields.

Creamy Seeds Buff

The Creamy Seeds buff is the primary reason players cook Mirthshroom Soup. When active, every crop you harvest has a chance to drop bonus seeds. More importantly, there is a small chance (estimated at roughly 5% per harvest by the community) that the dropped seed will be an immortal seed. Immortal seeds are the endgame of farming in Starsand Island: crops grown from them regrow automatically after every harvest without replanting, and they ignore season restrictions entirely, growing year-round.

How Stacking Works

Each serving of Mirthshroom Soup adds one stack of the Creamy Seeds buff, and the effect can stack up to five times. Eating five soups in a row gives you the maximum buff strength. At five stacks, players report getting a seed back with nearly every harvest, and roughly one in ten of those seeds turns out to be an immortal seed. The five-minute timer resets with each soup consumed, so eating all five servings back-to-back gives you a full five minutes at maximum potency.

The buff applies to all crop types. Whether you are harvesting Rice, Pumpkins, Strawberries, or any other crop, the Creamy Seeds effect has the same chance to trigger. This means you should time your soup consumption to coincide with your largest harvest sessions for maximum returns.

Buff Duration and Timing

Each serving provides 5 minutes of the buff. Since the timer refreshes when you eat another soup, the most efficient approach is to eat all five servings right before you start harvesting. This gives you a solid five-minute window at full stacks. If you have a very large farm, consider splitting your harvest across two sessions with a fresh round of soups for each one.

Where to Get the Recipe

The Mirthshroom Soup recipe is found inside a treasure chest in the Moonlit Forest. The Moonlit Forest is accessible through the portal behind the Damaged Door near your home. To open the Damaged Door, speak to Zephyria at the Exploration Club and complete the required quest. Once inside the forest, explore the various areas and open every treasure chest you find. The Mirthshroom Soup recipe scroll can appear in any of the forest's chests.

Once you pick up the recipe scroll, open it from your inventory to permanently learn the recipe. It will then appear in your cooking menu whenever you interact with a Gas Stove or Campfire.

Ingredient Sourcing

Mirthshroom Soup requires only two Mirthshrooms per serving. There are two ways to obtain them: foraging in the Moonlit Forest or growing them on your farm.

Foraging in the Moonlit Forest

Mirthshrooms grow naturally throughout the Moonlit Forest. They are described in-game as "a short-statured bamboo mushroom native to the Moonlit Forest, with a wide, lacy skirt and a striking blue-purple hue." Their distinctive appearance makes them easy to spot among the forest floor.

Resources in the Moonlit Forest respawn every day at 8 PM, so you can gather a fresh batch of Mirthshrooms on each visit. A single foraging run through the forest typically yields enough mushrooms for several servings of soup. This is the most cost-effective method since foraging is completely free.

Growing on Your Farm

If you prefer a more reliable supply, Mirthshrooms can be grown from seeds purchased for 25 Coins each. They grow in all four seasons (Spring, Summer, Autumn, and Winter), making them available year-round. Each plant takes 5 days to mature and requires regular Soil (not Paddy Fields or Planting Boxes). The crop sells for only 18 Coins, so the real value of farming Mirthshrooms lies in cooking them into soup rather than selling them raw.

For dedicated soup production, plant a small patch of 10 to 15 Mirthshroom seeds near your cooking station. With staggered planting, you can harvest a fresh batch every couple of days. Combine this with foraged mushrooms from your daily Moonlit Forest visits and you will never run short of ingredients.

Profitability

At 54 Coins per serving, Mirthshroom Soup is not a money-making recipe. Two raw Mirthshrooms sell for 36 Coins total (18 each), so cooking them into soup adds only 18 Coins of value. The 24-second cook time makes this efficient in terms of time, but the low sell price means this dish is not worth mass-producing for profit.

The true value of Mirthshroom Soup is strategic, not financial. By using it to farm Everlasting Seeds, you eliminate the need to buy new seeds for high-value crops season after season. A single immortal seed for an expensive crop like Star Mango or Pumpkin saves hundreds of Coins in seed costs over time and produces income indefinitely. The soup pays for itself many times over through the seeds it helps you collect.

Strategy for Everlasting Seed Farming

Mirthshroom Soup is the centerpiece of the most efficient strategy for acquiring immortal seeds. Follow these steps to maximize your seed farming results.

1. Stockpile Mirthshrooms: Before you begin, gather at least 50 Mirthshrooms through foraging and farming combined. This gives you 25 servings of soup, enough for five full-stack sessions.

2. Prepare your fields: Plant as many crops as possible across your farm. The more plants you have ready to harvest at the same time, the more chances you get during each buff window. High-value crops are ideal since their immortal seeds are worth the most.

3. Cook five soups: Head to your Gas Stove or Campfire and cook five servings. At 24 seconds each, this takes about two minutes.

4. Eat all five immediately: Consume all five soups to reach the maximum Creamy Seeds stack. This gives you roughly 5 minutes of the highest drop rate.

5. Harvest everything: Move through your fields and harvest every mature crop during the buff window. Each harvest has a chance to drop a regular seed, and a smaller chance to drop an immortal seed.

6. Repeat as needed: If your farm is large enough that you cannot harvest everything in one five-minute window, cook and eat another round of soups before continuing. Repeat this cycle every time your crops are ready.

This strategy pairs well with the Eternal Blessings skill unlocked at Senior Farmer rank, which independently increases your chance of getting Everlasting crops from regular harvests. When both the skill and the Creamy Seeds buff are active, your overall immortal seed drop rate improves significantly.

Related Recipes

Mirthshroom Soup is one of several dishes that use mushrooms from the Moonlit Forest. If you are already foraging Mirthshrooms on your daily forest runs, consider cooking these related recipes as well.

Tips

• Always eat five Mirthshroom Soups before harvesting, not just one. The stacking mechanic is the key to getting a meaningful number of immortal seeds. A single serving gives a noticeably lower drop rate compared to a full five-stack.

• Keep a chest stocked with pre-cooked Mirthshroom Soup near your farm. When your crops are ready, grab five soups, eat them, and harvest immediately. Preparation saves valuable buff time.

• Mirthshroom Soup is also a solid everyday stamina food thanks to its zero-cost foraging ingredients and 45 stamina recovery. Even if you are not farming seeds on a particular day, it makes a good quick snack while exploring.

• The recipe scroll is in the Moonlit Forest treasure chests. If you have not found it yet, make sure to open every chest during your exploration runs. Complete the Moonlit Forest questline through Zephyria at the Exploration Club to gain full access to the forest.

• Do not sell raw Mirthshrooms unless you have a large surplus. At only 18 Coins each, they are worth far more as soup ingredients for the Creamy Seeds buff than as a source of income.

• Mirthshrooms grow in all four seasons, so you never need to worry about seasonal availability. Keep a small dedicated patch on your farm as insurance against days when you skip your Moonlit Forest foraging trip.

• Combine the Creamy Seeds buff with the Eternal Blessings farming skill for the best possible immortal seed drop rate. If you have not reached Senior Farmer rank yet, Mirthshroom Soup is your primary way to get immortal seeds in the meantime.
