Multiclass Kits
With this mod it is possible to install true multiclass kits from any combination of single-class kits which allows unusual combinations such as Kensai/Assassin or Berserker/Wild Mage/Swashbuckler. Custom kits from mods are considered as well if detected.
The mod supports any Enhanced Edition games at patch version 2.0 or later, except PsT:EE. Project Infinity is supported as well.
