Seasons

**Seasons** refers to the quarterly division of an in-game Year, that is based on the Gregorian calendar. Each Season lasts 28 in-game Days. It affects (with a small offset) Cultivation Speed and Breakthroughs, as well as Agency disasters. The game starts on the 8th of Spring.

## Cultivation speed

The season (or more accurately the half season) applies a multiplier on cultivation speed, which is equal to 1 for cultivators of a Law of None (Element). For others, it depends on their Element and on the day in the year.

The exact multiplier for the day is calculated by determining your own DayYear and interpolating:

* in Spring, if you're before the 11 (included) add 111, and if you're after the 11 (included too) remove 1 from the current day in the season.
* In Summer, add 27
* in Autumn, add 55
* in Winter, add 83

Then find between which 2 values you are, and your multiplier will be

{\displaystyle LeftValue + (RightValue - LeftValue) \* \frac{DayValue - LeftDayValue}{14}}

.

* Example 1: on the 3 Autumn, DayYear is 3+55 = 58, which is between 25 Summer and 11 Autumn. For a Water cultivator, the multiplier will be

.
* Example 2: on the 25 Spring, the multiplier for an Earth cultivator directly corresponds to 1.1
* Example 3: on the 4 Spring, DayYear is 4+111 = 115, which is between 28 Winter and 11 Spring. For a Metal cultivator, the multiplier will be

{\displaystyle 1.3 + (0.9 - 1.3) \* \frac{115-108}{14} = 1.1}

.

## Breakthrough

The current half season affects the breakthrough chances, thus the Golden Core Quality. For a cultivator of a Law of None (Element), it has no effect whatsoever. For the others, it depends on their element and the day in the year.

The exact multiplier for the day is calculated by determining your own DayYear and interpolating:

* in Spring, if you're before the 11 (included) add 111, and if you're after the 11 (included too) remove 1 from the current day in the season.
* In Summer, add 27
* in Autumn, add 55
* in Winter, add 83

, treating the breakthrough chance as a fraction. For example, for a Fire cultivator on the 11th Spring, it will be 1.3.

## Agency disasters

Agencies are linked to certain disasters, and only these disasters can happen to them. The disasters themselves are linked to seasons and apart from Earthquakes, can only happen during those seasons:

* Flood only happens in Autumn,
* Drought only happens in Summer,
* Cold Wave only happens from Winter 1 to the 10th of Spring
* Earthquake can happen all year round.

## Spirit roots

The Bless/Curse tendency of Spirit roots also has a seasonal factor, detailed here.

## Effects on light and weather

### Weather

Some Weathers are season restricted, and those restrictions also apply to Miracles conjuring them. It has an important effect on the Weather factor in Breakthroughs.

### Light

Seasons do not directly affect Light, but the duration of sunlight during the day varies between the year, with the highest point being in the middle of summer, and the lowest point in the middle of winter. This has an indirect effect on yin-yang during Breakthrough.
