Pro-tip: The place where noct shield works best is speed runs. This is because there is better mitigation overall with Noct shield (since you benefit for parry more), but it is usually spikier due to lower block chance. With so many hits coming at you in SR though, it doesn't matter if you have only a 22% block chance, it will be consistent, hence suppressing the only disadvantage of the Noct shield.

I use Noct too and i love it, for everything. But wether it is better for Coil and single target tanking is the question; if you already use it for that, use it for SR too, since it is where it is at its best
