• KFServerExt.ini - stats and traits settings;
  
• KFServerExtMut.ini - general server settings;
  
• KFServerExtStats.ini - list of top players;
  
• KFxMapVote.ini - map change settings;
  
• KFxMapVoteHistory.ini - voting history, likes, dislikes.

Files are created when the server starts.
The contents of the KFServerExt.ini file will appear when you change something in:
WebAdmin → Settings → ExtServer Mod

They are stored in *.usa files, which can be found here:
They have a name that matches "Player Unique Net ID".

You can change their location by editing:
KFServerExtMut.ini → [ServerExtMut.ServerExtMut] → StatFileDir

You can specify the mode through the server startup options. This will work, but only for the first game. When changing the map, the RPG mutator no longer uses the startup options, but reads them from the KFxMapVote.ini.
To prevent the mode from disappearing, additionally specify it in:
KFxMapVote.ini → [ServerExtMut.xVotingHandler] → GameModes

Example:
Suppose your start options are as follows:

Then the value of GameModes should be like this:

You can specify several modes, one by one, to be able to choose from them.
Example:
In the game It will look like this (in the screenshot I did a little more):

There is no need to use other mutators for this, just change:
KFServerExtMut.ini → [ServerExtMut.ServerExtMut] → ForcedMaxPlayers

Go to KFServerExt.ini config and find the section with the perk you want to change.
Here you need lines like this:

• StatType is the attribute name;
  
• MaxValue is the maximum attribute value (your captain obvious);
  
• CostPerValue - the cost of one attribute increase;
  
• Progress - the value of one increase.

Thus, if you spend 5 points on health, you will get an additional 5 HP.
In this example, we can spend 5 points at once or spend them gradually.

But using the "CostPerValue", we can prevent the player from spending points gradually. Change the line like this:
As in the previous example, to get an additional 5 health, the player needs to spend 5 points. But now he needs to accumulate all 5 points to do this.

The trait mechanics and number of trait levels cannot be edited, but you can change the parameters that are available to you through KFServerExt.ini (or WebAdmin).
Find the section of the trait and edit the parameters that are there.
For example, for Ext_TraitVampire, these are:
- enable / disable trait;
- minimum level for trait;
- level costs (4 levels).

By default, the experience for custom zeds is calculated from the damage inflicted on them.

But the experience can be customized. To do this, add a line like this to the end of the KFServerExtMut.ini file:
After "zed=" you need to specify the name of the zed (in this example, it is "zedcustom.mrpelvis" from ZedVarient).
XP1 / XP2 / XP3 / XP4 set the amount of experience for normal / hard / suicide / hell difficulty.
in this example, you will get 15 experience for killing mrpelvis on normal difficulty and 35 for killing him in hell

For multiple zeds add one line after another.

Use Custom Trader Inventory:

❗️Set these parameters in KFCTI.ini as follows:
(enabling these options does not work with this version of ServerExt)
