Warmly = 1100 to 1450
Kindly = 750 to 1100
Amiable = 150 to 750
Indifferent = 0 to 150
Apprehensive = 0 to -150
Dubious = -150 to -750

You get 1 faction hit for kills in Lower Guk and about 5 faction hits for killing the faction giving frogs in Sebilis.
In the past, if your race is evil, you need wolf form or a goodie race illusion. If your religion was evil, you could use that scalp thing... if both, then need both the illusion and the scalp item. Not sure if it is the same anymore, been a long time since I have read about this quest.
This is the faction item:
