On a weapon with a 9% crit chance, no less!

There’s some kind of bugged interaction between Nyx’s passive and the Acuity mods that causes the passive to multiply after Acuity. I use a chain of “final” crit, Acuity, and Nyx passive to get a weapon with 9% crit to over 300% crit. As a bonus I demonstrate that radial weapons don’t even really need aiming and can still benefit from Acuity.

Passive

Nyx gains Thrive in Chaos whenever enemies within Affinity Range are afflicted with Confusion (from Radiation status effect or Mind Control), increasing her primary and secondary weapon Critical Chance by 40% per enemy up to a maximum of 200% from 5 enemies.

and

There’s gotta be something exponential to it, because +550% (200 + 350) won’t get a 9% crit chance to red crits.

9% * (3.5 + 2) = 49.5%
9% * 3.5 * 2 = 63%
I don’t know what it is here that does the trick.
