I just recently started running hard sword and been just playing it safe 3,3,3,3,3,3 with ogres. I've got full hunter raid gear and 2 weapons with +2 agility but just can't seem to get this fast. Any advice? How do you know when to hit so early but not too early where he's not going down and kills you instead?
