Its so hard and challenging at the beginning i simply love it ... Basically with this mod mixed with deadly Combat...IF you don't block properly before taking a hit you could die in just 2 hits. don't bother doing a dead is dead with this..you will die a LOT.. and every kill you do is satisfying.. First time its nice to be terrified of Saber cats , Orcs and other guys with heavy weapons....
I only save at towns and inns so am still afraid too loose and you have to pick your fights carefully its difficult to handle more than 1 guy at a time....
