I was fighting Optio Verdis in The Grotto, during the duel he got 4 critical hits, how many hit me? 0! I blocked every one, and my critical block is only 19. Was I lucky, or is there something about how criticals and blocks I'm not getting?
It's a matter of percentages in critical rates and critical rate is counted differently than critical block, In a way you were lucky, but in the end it's still a matter of this percentage beat that percentage basically.
