Nutrition — Why Food Is a System, Not a Stat

Rune Soul has a level system. Skills improve through use, and leveling gives you points to invest in your build.

But leveling tells you what kind of character you are. Diet determines how good that character actually is.

Think of it like vehicles. Two players both choose a truck build. Same class, same level, same spec. But one has been consistently eating for Stamina — foraging grains, baking bread, keeping their Yellow nutrition high. The other has been eating whatever they find. Same truck. Very different cab size. Very different engine.

That’s what diet does. It’s the trim level on the vehicle you’re already driving.

Two Layers of Effect

Food works on two timescales at once.

Short-term: Eating a food gives you an immediate boost tied to its nutritional color. Eating mana-heavy foods spikes your Mana regeneration rate right now. Eat something with strong Stamina value and you recover faster this fight, this run, this moment.

Long-term: The game tracks your dietary history over time. Sustained eating in a direction shifts your baseline — stat ceilings rise, regen rates improve, your character’s floor gets higher. A player who has been eating well for three in-game days is measurably more capable than a player who hasn’t, at the same level.

The constraint is time. You can only eat so much food in the hours you play. Every meal is therefore a decision — not just “prevent death” but “invest in a direction.” A meal is an opportunity.

The Color System

Every food maps to a color, and every color maps to a stat:

Red — Health. Meats, roots, hearty stews.
Blue — Mana. Mushrooms, herbs, essence-infused foods.
Yellow — Stamina. Grains, bread, dried goods.

Secondary colors (Purple, Orange, Green) split their nutritional value across two stats and add a third situational effect. Eating Purple might give you a Health+Mana split with a Mental State benefit on top.

The color you eat shapes the trim you’re building toward.

Every Specialization Has a Cost

You can eat only one color if you want. A player who eats nothing but high-quality Red food will build a real tank identity on top of their base level — higher Health ceiling, faster Health regen, a sustained investment.

But neglected stats decline over time. A pure Red diet starves Mana and Stamina. That’s not a bug — it’s the cost of specialization. You’re not locked out. You’re trading.

This means every hunger moment is a question: maintain the current direction, or shift? You’re always managing a decision, not just a bar.

The Sleep Buff

There’s a third layer: a daily active buff locked in at sleep.

When you wake up with a healthy mental state, the game captures your current nutrient ratios and locks a buff based on your dominant color. Eating Yellow-heavy, you wake with a Stamina buff proportional to how well-fed that bar is.

The buff holds until your next sleep — or until your mental state collapses to Delirium. Reaching Delirium clears the dietary buff entirely. No new buff locks in until you’ve recovered all the way back to Grounded.

Mental health management isn’t just atmosphere. It’s directly tied to whether your dietary build is working right now.

The Production Chain Matters

The deeper you invest in food infrastructure, the more powerful this system becomes:

Foraged / hunted ingredients  →  basic, low-color-purity nutrition
Cooked food                   →  cleaner color type, better stat gains
Preserved food                →  consistent intake, enables NPC attraction
High-quality meals            →  strongest long-term ceiling raises

Building a kitchen is a character power decision. A player maintaining a proper food chain will consistently outperform a player at the same level eating raw foraged ingredients — not because of arbitrary gates, but because the system rewards sustained investment.

Food variety also matters for your settlement. NPCs are attracted to towns with reliable food supply, and morale tracks dietary variety. A settlement producing only Red food will attract settlers but struggle to keep them happy.

What’s good for your character tends to be good for your village.

That’s usually how good production chains work.
