Deep Dive into Living Frigate Diet Mechanics: 133+ Unique Combinations and Min-Maxing Models

1. Core Principle and Seed-Based Generation
The mechanics of living frigate diets in No Man’s Sky revolve around cycling through unique food groups to find the most optimal stat combination for a specific ship. Every living frigate possesses a unique hidden identifier (a seed), making its individual reaction to each type of food entirely unique.
If "Syrupy Viscera" causes a trade stat spike for one frigate, the exact same item might shift another frigate's skills into combat, while a third one might start saving fuel or reducing expedition time. It is impossible to predict how a specific product will affect a specific living frigate without practical testing.

Through empirical testing, I have identified 93 unique food groups, including raw nutrients, that produce a distinct, individual effect on a frigate. The remaining 282 items (both wild plants/fauna and processed nutrient processor products) have duplicate effects.
This does not mean the groups are distributed evenly across the culinary matrix: for instance, 35 different types of baked pies will yield the exact same combination of C-class (blue) perks, whereas "Syrupy Viscera" provides its own isolated, unique effect.
A separate phase of research involves fishing products (raw, unprocessed marine fauna: fish, turtles, squids, crabs, etc.). I have logged 40 unique combinations derived from aquatic resources. In total, there are 210 fish species divided into 9 key biomes:
• Toxic
• Radioactive
• Frozen
• Scorched
• Lush
• Desert
• Anomalous
• Ocean
• Gas Giant
There are also 21 fish species from the common list that can be caught anywhere except gas giants. All aquatic fauna is divided into 4 ranks, where S-rank and A-rank take 4 positions each, B-rank has 6 positions, and C-rank has 7 positions.
Practical testing has established a clear rule: fish of the same rank from the exact same biome share identical properties when fed to a frigate. This means all 7 C-rank fish species from a toxic biome will produce the exact same effect; likewise, all A-rank fish from an anomalous biome will yield an identical result. However, the effects between these two groups will be fundamentally different. This provides exactly 40 unique aquatic combinations.

Based on current calculations, there are 133 unique combinations available in the game. However, it is worth noting that my research is currently missing the "The Angler" fish (a unique catch exclusive to the "Aquarius" expedition, currently unobtainable via standard methods) as well as "Ghostly Fillet"—a product processed from "The Angler" via the Nutrient Processor. Factoring in these two items, the real number of unique combinations in the game's code is highly likely 135.
Verifying this data on standard community platforms (Reddit, Wiki) was unsuccessful. Public sources still claim there are only 65 food groups. This information is severely outdated—the pool was likely expanded by the developers during the major cooking overhaul and the introduction of fishing mechanics.

When min-maxing combat stats via feeding, it is crucial to understand the strict algorithm the game uses to generate the final trait matrix. A living frigate has a strictly limited grid—a maximum of 5 simultaneously active perks. These traits are divided into three tiers:

1. "Core" Skill (1 slot): Strictly one per combination. It grants the highest single boost (+15 to a stat or -15 tonnes to fuel consumption) and defines the peak specialization:
   o Echolocation — +15 to Exploration.
   o Bitter Memories — +15 to Combat.
   o Haunting Voice — +15 to Trade.
   o Seismic Song — +15 to Industry.
   o Slow Metabolism — -15 tonnes to Fleet Fuel Consumption.
   o Wormhole Navigation — -10% to Fleet Expedition Time.
   Note: I intentionally consider expedition time reduction traits useless. Upgraded Freighter upgrade modules combined with three single-use "Fuel Oxidisers" per expedition can cut real-world mission timers from 28 hours down to 4. This baseline reduction is more than enough to completely ignore time perks in favor of pure combat stats.
2. "Support" Skills: These grant a +6 boost to a combat stat or cut fuel consumption by -9 tonnes. Two identical support perks (e.g., two "Hyper-Velocity Strikes") cannot appear in the same matrix, but two different perks for the same stat (e.g., "Muscular Tentacles" and "Hyper-Velocity Strike") stack perfectly, yielding a total of +12. They include:
   o Reality Slip / Gliding Motion (Fuel Cost: -9t).
   o Ancient Lore / Retrocognition (Exploration: +6).
   o Market Forecast / Forgery Detection (Trade: +6).
   o Muscular Tentacles / Hyper-Velocity Strike (Combat: +6).
   o Asteroid Digestion / Baleen Plates (Industry: +6).
3. "Tier-3" Skills: Minor modifiers. These include +1, +2, +3, +4 boosts to combat stats, -1%, -2%, -3% to expedition duration, and minor fuel reductions of -2, -3, -6 tonnes. In total, I have recorded 44 of these minor perks.
   

Based on overall efficiency, I have identified three optimal feeding models (ranked by practical value). The ultimate criterion for an ideal roll is simultaneous growth across all four combat stat branches, establishing a perfect four-vector balance.
• Model #1 (Absolute Maximum):
[+6 Combat] -> [+15 Core] -> [+6 Combat] -> [+6 Combat] -> [+6 Combat]
Example: +6 to Trade, +15 (Core) to Combat, +6 to Industry, +6 to Exploration, and another +6 to Combat (from a different perk branch). This results in a highly balanced distribution with a massive controlled peak in your primary stat.
• Model #2 (Economic Balance):
[+6 Combat] -> [+15 Core] -> [+6 Combat] -> [+6 Combat] -> [-9t Fuel]
Example: +6 to Trade, +15 to Combat, +6 to Industry, +6 to Exploration, and -9 tonnes to fuel consumption. The specific core trait type here is secondary—the main goal is maintaining the four-vector balance while maximizing logistical cost reduction.
• Model #3 (Compromise Balance):
[+6 Combat] -> [-15t Fuel (Core)] -> [+6 Combat] -> [+6 Combat] -> [+6 Combat]
The least optimal among the best. If, during a full diet map sweep, the core perk stubbornly skews the frigate too hard into one specialization (locking out growth in an remaining branch), you can utilize the -15 tonnes fuel core perk instead, covering all four combat branches exclusively with +6 support modifiers.

Throughout my research, pulling a mathematically flawless "Model #1" has not yet happened, but I have achieved results that are extremely close to it.
Frigate "Warrior" after being fed "Wild Milk". An example of a strong four-vector distribution with a +15 Core "Echolocation" perk and three +6 traits (including a minor +3 combat boost).

Frigate "Lucky Nelson" yielded the closest result to the baseline standard when fed "Grahaberry".

Frigate "Supernova Heart" fed with "Exploding Beans".

Finding and acquiring an organic vessel with high base potential is only half the battle. The final combat efficiency of the ship relies entirely on a meticulous selection of its individual diet. Due to the abundance of filler Tier-3 perks or destructive seed-based skews that turn universal balance into chaos, fine-tuning the matrix of each frigate remains a complex but vital engineering challenge for building the perfect fleet.
