Bioticum

Bioticum is the name given to an animal, mineral, or plant that can be placed by the giants in Reus 2. They fulfil the same roles as natural sources do in the original Reus, providing various resources to human cities. 
== Gameplay ==
=== Classification ===
Biotica are subdivided in many different ways. Firstly they are separated by type: either animal, mineral, or plant. Secondly, into apex biotica or cohort biotica, which effects how they are drafted. Apex biotica always have a significant biodiversity cost, while cohort biotica generally do not. Thirdly, they are separated by the type of biome, or biomes, that they can be placed in. Fourthly, they are separated by their level: 1-star, 2-star, or 3-star. This affects where they can be placed on the planet, and from which era they can be used. Lastly, they are separated by their tags. Each bioticum has a number of different tags signifying features of that bioticum. While tags and types don't do anything by themselves, they are used to determine the effects of other biotica, and projects, placed on the planet. 
=== Placement ===
Biotica are placed by your giants in slots on the planet. Each giant can only place one type of bioticum. To be placed in a slot, the player must spend 5 Eon, pay the bioticum's biodiversity cost if it has one, and the slot must match or exceed the level of the bioticum the player is placing in it. All slots begin the game at level 1. To increase a slot's level, you must spend an Upgrade Charge. Upgrade Charges will level all slots in the chosen patch to the level of the current era, 2 if in the Medieval era, or 3 if in the Age of Discovery. In Sandbox mode, Upgrade Charges will level them to 3 regardless of the era. If there are already biotica in a slot when it is upgraded, they will be stored as legacy biotica. This removes the bioticum from the slot, but preserves its current yield forever. If you wish replace a bioticum with another bioticum, the same conditions must be met. However, replacing a bioticum only costs 1 Eon instead of 5.
Each slot is considered adjacent to a number of other slots, indicated by the lines that connect different slots together. Knowing which slots are adjacent to which are important for activating the abilities of biotica. The maximum adjacency a slot can have is four, however using a mountain will create a slot with six slots adjacent to it. 
=== Resource Generation ===
All biotica provide resources: either Food, Science, Gold, Mystery, Biodiversity, or some combination of them. If a city controls a patch where biotica have been placed the bioticum in that patch will provide their resources to the city. You can increase the amount of resources a bioticum can generate by activating their abilities, or equipping them with micros. There are many different biotica abilities, but a lot of them rely on placing them next to other biotica with certain types or tags.
=== Drafting ===
At the start of a planet, each biome has only six biotica available to use: two animals, two minerals, and two plants. The only exception to this is Desert, which only has one Plant instead of two. Below is a table showing a list of the initial biotica for each biome:

The main way of getting new biotica to use on a planet is by spending a draft charge to draft a new apex bioticum. When players spend a draft charge they choose which biome they are drafting a biotica for, and are then given a choice of three apex biotica to pick from that biome that the player has unlocked. Each apex biotica has several cohort biotica attached to it. When players pick an apex bioticum, they unlock the ability to place it and any of the cohort biotica attached to it. If the player doesn't like any of the biotica offered they may use a re-roll charge to Players gain draft charges by completing City Requests, but they may also spend food, science, or gold, to buy additional ones from the Planet Shop.
The first apex biotica draft you do for each biome will only let you choose between the three 1-star apex biotica of that biome, and you cannot use re-roll charge on this draft. For each biome, the first 1-star biotica will focus on generating Food, the second on Science, and the third on Gold. Below is a table showing the initial draft options:

In Horizon Draft, you begin the game with up to three apex biotica and their cohorts already unlocked, one for each era in your game. These biotica will be randomly selected from the primary biomes of your chosen giants. The level of the apex biotica chosen will also match the levels in your game. For example, if your game only lasts until the Medieval Era, you will get two apex biotica: one 1-Star and one 2-Star plus their cohorts. The biome that the 1-Star apex bioticum belongs to will not force you to pick another 1-Star apex bioticum on your first draft.
