In the unforgiving high-altitude survival game
PEAK, proper resource management is the thin line between a successful expedition and a tragic demise. While simple food items can offer a crucial lifeline, the recently introduced
Shroomberries add a chaotic layer of risk and reward to your diet. Found exclusively in the dense, fungal environment of the
Roots biome, these seemingly innocuous plants can either grant you godlike temporary power or leave you paralyzed and exposed.Successfully navigating the unpredictable effects of Shroomberries is not only key to survival but is also the prerequisite for unlocking one of the toughest new achievements: the
Advanced Mycology Badge. This guide breaks down where to find these colorful fungi, their chaotic effects, and the best strategy for consuming all five types in a single run.
PEAK: How to find all shroomberry types
The Fungal Feast: Locating and Understanding Shroomberries
Shroomberries are a unique flora exclusive to the newest map addition.
Where to Find Shroomberries
- Exclusive Biome: Shroomberries spawn exclusively in PEAK’s Roots biome. This biome appears randomly as the second level of an expedition, replacing the Tropics on specific runs.
- Appearance: They grow on the ground and up the mountain, often resembling small, brightly colored mushrooms.
Basic Effects and Drawbacks
- Positive Effects: Eating any Shroomberry will restore hunger and grant a bonus to your stamina bar, offering immediate, crucial survival benefits.
- The Cost: Regardless of color, consuming a raw Shroomberry will inflict a small amount of spore damage, slightly filling your spore damage bar.
The Rainbow of Risk: All Five Shroomberry Types
There are five distinct Shroomberry types, each easily identifiable by its unique color and pattern.
| Color | Pattern |
| Red | Squiggly lines |
| Green | Stars |
| Blue | Sprinkles |
| Purple | X shapes |
| Yellow | Spirals |
The Chaotic Nature of Shroomberry Effects
The true complexity of Shroomberries lies in their secondary effects, which are randomized and highly volatile. Crucially, these effects do not change with each individual expedition, but they change with every map rotation. If a purple Shroomberry is beneficial today, it might be detrimental tomorrow when the map is re-rolled.
Observed effects include:
| Beneficial Effects | Detrimental Effects | Novelty/Utility Effects |
| Unlimited Stamina (temporarily, similar to the Big Lollipop) | Inflict extra spore damage | Fart sound effect and cloud around the character |
| Faster Climbing Speed (temporarily) | Temporary paralysis (your character falls to the ground) | Stamina bar disappears (replaced with mushrooms) |
| Removes a small amount of spores, injury, and other ailments | - | - |
Mitigation Strategy: Given the unpredictable and sometimes lethal nature of these effects (especially the temporary paralysis), you can cook your Shroomberries over a portable stove or campfire. Cooking them can help mitigate some of the most dangerous detrimental effects, making the pursuit of the badge slightly less risky.
The Advanced Mycology Badge Strategy
The Advanced Mycology Badge is a testament to both your scavenging skill and your willingness to gamble with your health.
The Core Requirement
- To obtain this badge, you must eat all five Shroomberry types (Red, Green, Blue, Purple, Yellow) within a single expedition.
Strategy for Success
- Luck and Persistence: The trickiest part is simply finding all five colors in one run. The berries spawn randomly, meaning you cannot rely on memory. Thischallenge requires a bit of luck and a lot of thorough exploration ofthe Roots biome.
- Evaluate the Risk: Before consuming a new color, evaluate the known risks for the currentmap. Since some effects (like paralysis) can be extremely detrimental if you're near a Roots biome zombie or have low health, always try to consume them in a safe, isolated spot.
- Leverage Positive Perks: If you discover that a certain berry color grants a powerful positive perk, such as unlimited stamina or faster climbing speed, use that boost to your advantage. Consume it and immediately use thetemporary speed to scour a wider area of the map to search for theremaining colors.
- Prioritize Cooking: If you have access to a stove or campfire, always cook the berries first to mitigate the chance of an instantaneous, run-ending detrimental effect.
By treating the Roots biome as a pharmacological experiment, prioritizingsafety during consumption, and committing to deep exploration, you cansuccessfully collect and consume the required fungal quintet, earningyour prestigious Advanced Mycology Badge.
