from my experiences with a fast roll character its almost too easy unless caught off guard.
Pursuers- as soon as they all come towards you roll straight into them and you won't be harmed, they will go right past you
Dark Beads- almost the same method make sure you press the foe, get as close as you can so as soon as its cast roll forward into the enemy and you won't be harmed (or slightly harmed if the roll isn't perfect still not enough to stagger you) because they will go over your head
I'm telling you works like a charm keep calm and roll
the enemy usually will continually spam and eventually you can catch them slipping they usually lack poise
