Spawn Map Instruction Manual

From ARK: Survival Evolved Wiki

This page is designed to explain how to use and read the information on the Creature Spawn Maps.

If you are viewing the map through the Ark Wiki App, it will not function properly, if at all. You must view it through a web browser in order to properly use it. If you are viewing on a phone's browser, both desktop and mobile view will work, but switch to landscape orientation for best results.

All group names for creatures and spawn areas are taken from the DevKit, so some of them may look a little weird.

Guide[edit | edit source]

This guide will walk you through the basics of the spawn map. For this example, we will be looking at the spawns of Ankylosaurus on The Island.

Step 1[edit | edit source]

Spawn Map Step 1.jpg

We start by clicking on the drop-down list to select a creature. Every creature is available in the list, including variants such as Unicorn and Yeti, but it is currently not possible to have multiple creatures displayed at once without viewing the full spawn groups (explained in a later step). We're going to select Ankylosaurus for this example.


Step 2[edit | edit source]

There are now multiple colored rectangles overlaid on the map. Each of these rectangles represents an area that the Ankylo can potentially spawn in. Anywhere without a rectangle has no Ankylo spawns, although they can wander a short distance outside of a rectangle. If you hover your cursor over one of the rectangles, it will display the coordinates of the upper-left and bottom-right corners of the rectangle. If it is a small circle instead of a rectangle, it represents a specific point where the creature can spawn, rather than an area (such as a Thylacoleo spawning on a tree), and hovering will display that coordinate. The color of each rectangle represents how common a creature is in that rectangle based on the max number of that creature that are allowed to spawn in that rectangle and how big the area is. The closer to green each individual rectangle is, the more common the creature will be in that area, and the closer to red, the rarer.

We now have spawn areas, so let's look at spawn chances within those areas. Uncheck every spawn group except for one, Mountain. You can see that the top-level spawn is 6.2% here - that means that each one of those colored rectangles has a 6.2% chance to spawn an Ankylosaurus. Under that top spawn, we can see more percentages - the first is the chance to spawn one Ankylo, the second, a chance for two, and so on. So in the Mountain spawn group, each rectangle on the map has a 6.2% chance to spawn an Ankylosaurus, and if that is successful, there is a 100% chance for the first spawn in that rectangle, a 75% chance for the second, and a 50% chance for the third.

Please note that while the spawn amount for this creature in this spawn group can be up to 3, with the chance decreasing linearly, each creature and spawn group will have their own amount and percent chances, so this formula should not be applied universally. Some creatures, such as Raptor are guaranteed to spawn in groups in certain areas.

Have a look at Basilosaurus or Yutyrannus specifically. They always spawn together with a number of Mantas and Carnos respectively, so you will see one line for Basilosaurus or Yutyrannus at 100% and some lines of Mantas or Carnos also at 100% each in the same group.

Step 4 (Optional)[edit | edit source]

Spawn Map Step 5.jpg
Keeping in the Mountain spawn group for our Ankylo, if we check the "Full Spawn Group Details" box, we can see what other creatures share this same spawn group, and see what is most likely to spawn in these areas. Looking at this screenshot, we can see for example that a Saber is twice as likely to be chosen to spawn compared to our Ankylo, at 12.5%. The screenshot does not show the whole list, but a Procoptodon has a much lower chance to spawn in these areas, at 0.9%.


Alpha Predators[edit | edit source]

Alpha Predators share the same spawns as their normal versions, but each time a normal version spawns, there is a chance it will be an alpha. The chances are as follows1:

Creature Spawn Chance
Alpha Carnotaurus.png Carno 0.79%
Alpha Leedsichthys.png Leedsichthys 3.19%
Alpha Megalodon.png Megalodon 0.99%
Alpha Mosasaur.png Mosasaur 16.67%
Alpha Raptor.png Raptor 0.99%
Alpha Tusoteuthis.png Tusoteuthis 6.54%
Alpha Rex.png Tyrannosaurus 0.62%

1Custom maps may have different values

Spawn Limits[edit | edit source]

Each creature has a percent limit to how much of a spawn group it can make up. The Ankylo, for example, can not make up more than 15% of the actual global spawns of the mountain spawn group. These spawn percent limits are currently not displayed on the map, but may be integrated at a future date.

Some creatures, such as Giganotosaurus, Quetzal, Unicorn, and Titanosaur have exact global limits, so they can't naturally spawn more than a certain amount.

Land and Water[edit | edit source]

Land-based creatures can not spawn in the water, and aquatic creatures can not spawn on the land, even if a square suggests otherwise.
