Have 2 accounts so I basically just spam Kindred Seals on every character.

You can buy all the shanks for 1k that you want. But 30 Kindred Seals for a go at the pot BCNM with a few items that sell for 100k-400k as potential drops is way better value in my eyes.
I can get usually 450 of the things at least per character. Minus any unique trusts and such for my main two characters.
