How Should I Go About Getting 100% Critical Rate?

Does this really work? Star Gazer completely cancels out regular Sharp Eyes.

oh, probably not then. It used to happen that if buffs had parts that did not stack with each other, such as an att+acc buff with an att buff, you still got to keep the accuracy part of the first one, so long as you did them in this order.

Guess they didn't do that with SE/Stargazer.
