Enhanced Difficulty (U11b4) is an experimental mod for the game Blade and Sorcery, where the combat system has been modified to make the difficulty level of fighting the opponents be more intense and realistic compared to the original game that some might find very easy and not challenging enough.

The first thing you should know about the combat system is that it has been changed. 
The enemies are now harder to attack and hit. They have a higher health and they can now parry your attacks. The recoil enemies get are also reduced for better balancing.
