Dark Knight Megathread

[Kaixern]

I wanted to ask (genuinely, i want to be sure)
Does an excog that is meant to be activated at 50% of your life and a shield that is meant to prevent your life to go down at all/as much as possible syngergize well?

(Maybe this question is stupid and those defensive abilities were never meant to be used together, etc...but i would rather ask this to dark knight players, and even many of those who have raided and did ultimates for some, in order to be sure what i "feared" was unfounded, even if the question was unecessary)
(Also sorry in advance for my bad english in case of mistakes)

edit: just looked a bit better and saw the excog activated at the end of the duration so it's good then right?
