Also use your pendant earlier it has lingering magic that blocks magic still after 1 sec.

80% of attacks are slams and they are safe for 2-3 attacks. After he slams you roll back and just attack his arm. If he screams mid fight roll back as far as you can as he is about to do his crazy knock up combo. He also as a super long ranged sweep that can be avoided by rolling back or left, right but requires good timing. Keep distance and don't attack until he uses any of his slams (close range or long range).

i dont lock on because of 8 directional roll and i am already using pendant as you can see :P

all you have to do is lock on a roll back for every single one of his attacks except for his sweeps and crazy combo. Also use pendant for magic.

strong magic shield? it is 15 int. if you meant stronger shield not enough end for blocking manus combos

try using a strong shield
