Eh, I went sorcerer, I haven't practiced parrying a lot or using shields. Getting the timing down is quite hard, I'm usually early...I'll try that. Then I went to Tower of Flame and tried shield using, aha, I see your point Daniel.
So I am good at dodging already, but there is one attack I can't seem to roll out of...Oh and 40% you say? I thought 50% was the marker for pathetic rolling..
70% is enough to roll decently. With Pursuer, just be very patient as the fight can take a long, long time if you are not able to do the parry + ballista (I can't get the timing right). You just need to roll, roll, roll, roll, roll.
