This is a rough NPC to gain amity with, but it's still not Wave worthy. Prepare to rage.
Basically what you want to do is go to the very back of the list and and scroll back and do this:

Gahaz Tuval -> Sander -> Zahad -> Geniefa

To be fast you can click Gahaz Tuval -> Sander -> Danio -> Geniefa -> Unclick Danio -> Zahad so that you can just scroll left without going back. If you roll too high of an interest level you have to restart, and if you roll an interest level of around 15 or lower you can replace Gahaz Tuval with Zobadi. I got 1k favor in about 330 energy
