Mages can and do get blocked, It doesnt happen often, but it does happen. Break does nothing to help your mages ability to hit though in terms of misses as confirmed by dawnseeker in another thread. IN HR and Quests as you get tougher and tougher bosses and in HP due to the tweaked stats of the statues you will see mages get blocked. Aso bosses in HR And quests sometimes have special abilities you see no where else so blocked mages could happen more often. SO infalibility is not a total wast eon a mage, in fact there are times you might need it.

In terms of blood, I have never witnessed his skill attack be blocked, or if I have it just never occurred to me that a skill attack was just blocked. SO I will have to start paying attention. However, when it comes to HR and quest bosses, the normal rules do not always apply and strange things you think are impossible can and do happen.
