Will this actually work? Still actually needs some testing but here's some numbers

Gonna use this with my Critical Gimmick Wisp build,

If I calculated this right- you should get 88% Crit Chance before [Critical Surge] on [Sporothrix] with everything procced, including Avenger. I'm awful at math so I can't say for sure if this is true or not.
Okay so actually yeah- right now in game I have 224 strength, 22.4% Crit Chance on base.
So if we do
1 x (1 + 22.4 + 20) + 45 = 88.4
1 is the base Crit Chance % on [Sporothrix], and for [Critical Surge] the crit chance is affected by ability strength, giving us 22.4% (for 1 meter) with 20% Vigilante Set bonus and the 45 from Arcane Avenger, you'll have 88.4% Crit Chance.

And with the max range porting with Critical Surge-
1 x (1 + 350 + 20) + 45 = 416
1 is the base [Sporothrix] crit chance, 350 for max [Critical Surge] crit chance bonus, and the 20% from Vigilante Set bonus, plus 45 from Arcane Avenger, you have 416.

Certainly this is much easier and simply achieved with [Harrow], but what's the fun in that? Well considering you have Condemn and can subsume Breach Surge onto him anyway... bleh.

Pair with Sentinel and weapon of choice, such as A Far Superior Cryotra - 95% Status Viral/Elec Proccer - 3 Vigilante Mods - Only 3 Forma [Verglas] build, not mine.
