So what's the drawback or what skill is required? Do you need to press them at the same exact time, or if you're getting chipped by a special can you just press those buttons after blocking and it'll negate the chip damage? --- [This message was deleted at the request of a moderator for no reason]
It works like TvC, were it's essentially push blocking It also act's as a extra shield in a sense, where in a sceneria were your getting chipped say by Storm's hail storm you rapidly advance guard to negate as much chip as possible. Making the chip you take minimal.
You'll notice a good diffrence in chip when you advance guard as opposed to just guarding.
