Monk Shackle of Clay -- faction needed as a human?

[maximum]

TL;DR: as a human monk, what faction level do you need for the Shackle of Clay?

I've been farming faction for over a month near Cabilis, and I'm finally Indifferent faction with the Swift Tails, but I still can't trigger Master Raska to receive the First Rite Pack:

[Sun May 20 18:50:48 2018] You say, 'what is a whiff?'
[Sun May 20 18:50:49 2018] Master Raska says, 'A whiff is the sound of a tail striking air. A whiff is you. Inexperienced. I can help you. If you [want to earn the second shackle].'
[Sun May 20 18:51:47 2018] You say, 'i want to earn the second shackle'
[Sun May 20 18:51:49 2018] You say, 'i want to earn the second shackle'
[Sun May 20 18:53:51 2018] Master Raska regards you indifferently -- looks like he would wipe the floor with you!
[Sun May 20 18:53:55 2018] You begin to sneak...
[Sun May 20 18:53:56 2018] Master Raska regards you indifferently -- looks like he would wipe the floor with you!
[Sun May 20 18:53:58 2018] You say, 'i want to earn the second shackle'

Do I need fricking Amiable?
