Questions about the Rod of Insidious Glamour quest

[eddyystop1999]

I'm working on getting a Rod for my noob enchanter.

The wiki says you can MQ the A Shining Stone with Cynthia in Rathe Mountains, so that is fine.

1. Does anyone know if a non-enchanter can hand in the second (Tarn Visilin in High Keep) and third steps (Sultin in the Temple of Ro) of the quest?

2. The noob obviously isn't killing the Shadowed Men and can't group for the kills. Does anyone know about how many Shadowed Men have to be killed to be amiable to Tarn Visilin?

Thanks in advance.
