Blockhitting automatically blocks with a sword and hits your opponent making you only lose 50% of the damage towards you and the opponent losing more hearts, when BlockHit is activated then you will block when you hit.

For this to work you need to be playing 1.8 - 1.8.9 because any versions above blocking with a sword was removed and replaced with shields.

And you need to of course download Wurst

Instructions: Now simply hitting with BlockHit on, will automatically block.
