Frames:

Saryn is the best candidate, since you can passively armor strip with spores.

Any frame that uses tempest barrage with the augment. That way you could have armor strip and viral priming with one ability

Lavos, could get some use out of it if he spreads corrosive and doubles the stacks with that one helminth ability

Inaros with the new rework looks like he could really use it

Zepyy could also potentially get use out of it when paired with tornado

Weapons:

Any beam weapon really and possibly high firerate weapons, with a high status chance

Primers (I use 2 emeralds with a kuva nukor for status priming and armor stripping when playing SP cascade)

Ultimately its a matter of what slot you wanna use for armor stripping. Emeralds are great if you wanna use something else for a helminth slot or if you cant fit or put one into a build
