In Xenoblade Chronicles, sometimes when a character hits it displays two grey shield icons next to the damage dealt. I get that it's a reduced damage notification, but why am I seeing it, and what can I do to not get these sort of hits to occur?
I read up online and seemed to come across a "Block Rating" mechanic in the game that enemies and player characters have, but I couldn't find any information on how to improve or bypass that value in combat. Any ideas?
