This “Empires” patch focuses on making the AI more dangerous and diverse. There are more than just monsters roaming the world, and the AI players have been updated based on feedback from the fans to be more effective in both strategic and tactical mode. AI players are now more adept at using their magical power, building more lethal armies, protecting their territory, pathfinding and more. Even the AI for the random monsters has been improved, allowing them to better guard their lairs against adventurers.
In addition to the vastly improved AI system, the 1.3 update includes updates to the Hiergamenon to bring all its entries up to current rules, UI improvements, gameplay balance updates, bug fixes and a new spell called Ineluctable Vision.
