Perkalator: The 7 Days to Die Skill and Perk Calculator

The main purpose of the Perkalator is to help players plan out how to spend their skill points, and share their 'builds' with other players, for both vanilla and modded games. It's interface closely matches that of the in-game Skill List appearance as of Alpha 17 but has numerous features and settings that take it beyond the in-game interface to make it much easier to make your skill selections.

In it's launch state support is included for A15,A16,A17 and [WIP] Console versions, as well as several mods already available: Darkness Falls, Ravenhearst and Sorcery Mod for A17, and War of the Walkers for A16. You are free to choose any skills you wish, and their skill requirements are are automatically added as well, with warnings given [by default] if you try to remove a skill (or skill level) that is required by another selection.

Hovering the mouse over the BUY icon for any rank, or one of the purchasing buttons, will show you the requirements for making that purchase. There are a number of options available (in Settings) to change how the Perkalator behaves, how it presents certain information to you, and how you spend your points, which are saved across visits to the site.

Loading / Saving / Sharing

You can save your selected skills at any time, to share them, or come back to them later. Every saved skill tree will have it's own unique URL e.g.

  • https://perkalator.co.uk/tpl/BasicLevel40TreeByMe
  • https://perkalator.co.uk/tpl/Awesome-YouTuber/Alpha17-Season4-Vanilla

A password must be set when saving, and must be used when loading if you wish to make changes to the skill tree (you can otherwise save as a new template, e.g. if you want to copy and edit someone's shared selections)

Purchase Options
  • Automatically remove skill levels that are no longer required
    • If enabled, then when removing skill levels, any skill levels that were automatically purchased as requirements will be refunded when they are no longer required
    • e.g. in A17.2 selecting "Hammer & Forge (2)" will automatically add "Intellect (5)"
  • Allow removal of required skill levels
    • If enabled, then any dependant skills will have their levels lowered to fit the newly selected skill level
    • e.g. in A17.2, changing "Hammer & Forge (2)" to "Hammer & Forge (1)" will change "Intellect (5)" to "Intellect (4)"
  • Include points from starter quests [Default: on]
    • If enabled, available points will include those from completing the starter quest "basic survival" as well as any starter quests specified by a chosen modded source
    • e.g. in Sorcery Mod you will have 11PTs extra from "basic survival" and the sorcery starter quest line
  • Set a purchase limit
    • If enabled, will limit the maximum spending in the perkalator to the specified number of Skill Points or a maximum Player Level
    • This can be useful if designing an early game build e.g. in A17.2 setting a Player Level limit of 40 will prevent purchase of "Advanced Engineering (3)" as it requires "Player Level (60)"
  • Skill points per level multiplier
    • Applies a multiplier to the skill points earned per level over the setting supplied by the XML source
    • This can be used if you use a self modded progression file that gives extra points in this way. Note: this may not behave as expected with modded sources such as Ravenhearst that give a skill points boost at certain player levels
  • Add a fixed number of skill points
    • Increases the total number of skill points earned by the specified value to represent extra points earned from quests or items
    • e.g. Challenge quests or Skill Notes from some modded games give extra skill points
    • This will probably be replaced in the future with a feature that augments this value from items/quests from the chosen xml source based on user input
  • All action skills have 0PT cost
    • If enabled, forces all action skills to cost 0PTs [Default: on, resets to on every page load]
    • This is a temporary setting until better support for action skills is implemented for pre-A17 and A17+ modded sources that bring them back
Display Options
  • Only show total points cost on skill levels [Default: on]
    • controls whether purchase/refund tooltips show a single total points value, or individual points values for the skill and any requirements
  • Disable custom text colouring
    • e.g. Sorcery Mod includes coloured text, and some people may find it difficult to read the coloured text
  • Skill list length [Default: 13, auto scales down on smaller windows]
  • Max skill levels to show [Default: 10, auto scales down on smaller windows]
    • These will change the size of the view for skills and skill levels, they will auto-scale down on page load if the windows is too small to show the defaults, but there are limits to how big/small you can make these
XML Sources

Choose from one of the already available xml sources by choosing the Game Version (Alpha 15 -> Alpha 17, or [WIP] Console, defaults to latest supported Alpha) and then the File Source (sources are grouped by vanilla and modded sources)
You can specify 'When changing XML Source' to either "Choose new skills" [default], or "Copy chosen skills/template" which will attempt to transfer your currently selected skills, or loaded skills, to the new xml source

All xml sources have their own unique URL, like saved skill templates do, which can be seen in your browser address bar when you change sources. Some special URLs exist for specific xml sources which get updated to always point at the latest version e.g.

Keyboard Controls

Most actions within the perkalator can be controlled via the keyboard instead of just the mouse. You can see all the available keyboard controls and rebind any of the keys in the Settings area.
Note: some keys will interfer with your browsers built-in keyboard shortcuts. e.g. if you bind F5 to an action, some browsers will no longer respond to F5 to reload the page


There is a small basic tutorial available, which can be launched from the {Help} button (or from the initial welcome message if you haven't already discarded it from appearing again)
There are also options to send feedback, request features or mods to be added, as well as bug reports if anyone finds a problem and is inclined to let me know.


The Perkalator site is still in ongoing development, and you can see the current roadmap here

This page outlines some of the features that will be worked on and added in the near and far future, with some slightly ambitious plans for site expansions at some point depending on the success of the site, and available time for development
