Waving is your best option I think.

Recommend completing the map quests for +200 amity.

All but one knowledge were 0~0 interest.
I used the following for 2 rounds (~29 amity), repeat. ~275 energy spent for 601
Farisa
Sorio
Oberin
Sameh
Nasrin

Seek out the best Combo effects to get to higher favor and weave in the one actually giving Favor: Sameh. Like this:
Eugene
Daraia
Sameh
Oberin

If you need to fail; you can't. Exit and start over.
I stopped after ONE turn each time, giving between +10-24. Better than waving
