The INI files will be present in one of two locations:

• Documents\My Games\XCOM 2\XComGame\Config\XComBladestormCustomizationV2.ini
  
• SteamApps\workshop\content\268500\869566977\Config\XComBladestormCustomizationV2Defaults.ini

The first file gets automatically generated whenever you save settings using ModConfigMenu.
For duplicate configuration values, the first file gets preference over the second.

Configuration options incude:

Set to 0 for reaction attacks and 1 for standard attacks.

Allow Bladestorm attacks to critically hit.

Apply an aim penalty to all Bladestorm attacks. Expects a decimal value. For example, a value of 0.3 is equal to 30% penalty.

Allows Bladestorm to trigger for enemies which move out of your attack range.

Increase the range of Bladestorm.

Setting this to true will cause this mod to not hook into default Bladestorm template, effectively disabling this mod. Use for bug testing. Requires game restart.
