Seed Mechanic

Summum Aeterna includes a unique world generator system never seen before in the genre, the Seed Mechanic... Each one generates a unique world with different enemy behavior, special events, and even a larger map size, depending on the rarity and the genes contained in the germinated seed.

This is the main feature that differenciates Summum Aeterna from other Roguelite games. Let's dig into this cool mechanic and see how it works!

## Terminology

#### Seeds

Mysterious items that germinate create portals to worlds. Depending on their shape, they will germinate a certain world.

#### Genes

They determine the properties of the seeds and the worlds they germinate.

#### Positive Genes

Genes that provide benefits. They increase with rarity and seed level, and the new ones are unlocked by increasing the difficulty.

#### Negative Genes

These provide disadvantages. They increase with the seed level and determinate its weight, and the new ones are unlocked by increasing the difficulty.

#### Dominant Genes

Genes that can't be modified when mutating a seed.

#### Codify Genes

Their descriptions remain always hidden. Do you like surprises? If not, sorry for you.

#### Exotic Genes

Genes available only for special events or inside unique seeds.

#### Rarity

It establishes the properties of weapons, seeds, gems and consumables. From lowest to highest: Common, Uncommon, Rare, Epic, Legendary, Mythic, and Relic. The higher the rarity of an item, the better its attributes.

#### Weight

It is the result of adding all the negative genes contained in a seed as well as its rarity. The greater the weight, the greater the difficulty and better final rewards. It has nothing to do with carbohydrate consumption.

#### Luck

Affects the rarity of weapons, gems, consumables, curses, and other stuff. The higher the luck, the higher the chance of higher rarities.

#### Influences

High level modifiers that alter the properties of the seeds by unleashing special conditions. They have a specific "skill tree" to upgrade them.

## Genetic Machinery

Yado's cabin, located east of Famished Town, hides the 3 genetic machines inside. Each one fulfills a specific function:

#### Germinator

It's the most important device you'll find in Summum Aeterna, and the centerpiece of the seed mechanic. It allows the player to check all the available seeds, see their attributes, genes, possible influences, and, of course, germinate them to create new worlds. You will use this device countless times!

#### Fusioner/Recycler

This machine has a double funtion. As its very name suggest, players can use it to fuse seeds into one of higher rarity, and also to recyclethose that won't germinate and get runes in return. An ideal device to "clean" the seed list, get some rarer ones or more runes in case you need them.

#### Genetic Disruptor

It was designed to alter the properties of the seeds. It allows you to transmute genes, add or remove influences, decode them... The options are endless. This machine is perfect when you feel creative and want to unleash your imagination. Yado is not responsible for any possible negative consequence.

## Seed Influences

#### Will of the Kings

Those seeds influenced by the Will of Kings allow the player to germinate a world where they will not be able to change their chosen weapon at the start of the adventure. No changes allowed, the one you get at the beginning will be the same oneyou end up with. However, you will be able to upgrade the chosen weapon in the royal forges to unimaginable limits.

#### Dominion of Chaos

The seeds affected by "Dominion of Chaos" will contain rooms flooded with chaos, these will contain unique enemies born from the pure essence of Chaos, in addition, there is a possibility that in these affected areas the fearsome "Hand of Chaos" will appear, sent to exterminate all life. Seeds affected by "Dominion of Chaos" will grant unique wishes based on the Chaos energy collected by the King of Darkness, increasing his power to legendary levels. They will also contain "Chaos Chests" which will grant a large amount of Chaos energy when opened.

#### Legacy of the Arcana

Those seeds influenced by the Arcana will allow the player to get arcane cards in the germinated worlds. The King of Darkness will find the Arcana cards in the influenced worlds eliminating the dream hunters, but it will be the cards that decide for themselves when to activate. Each Arcana card will have its own consequences and will alter the world. The initial deck will have 3 cards, the rest are unlocked by progressing in the worlds influenced by the Arcana.
