OP here, it's important to note that stance based slam attacks also do proc the tentacles at a 50% rate just like regular air-based ones. I've also found that certain ground finishers also proc the tentacles. Works with all non-fist-based weapons. Because fist finishers register as regular attacks instead of slam attacks for whatever reason.

So to recap, ALL slam attacks cause tentacle proc, even slammy ground finishers.* ( * Unknown if bug, subject to change.)

Tentacle proc DOES draw from Pilfering Swarm augument.

Do what you will with this information, Tenno.
