En effet le plus simple est le domaine de varajar. Si tu veux avoir le meilleur rendement récupère la quête "The Path to Revelations" (désolé pas accès au jeu là saurais pas te dire le nom exact en français) qui se récupère au Havre Terni ; le fait d'avoir cette quete fait apparaitre des "facettes" qui sont cahcunes considérées comme des boss, et rapportent donc toutes des points norns.
Se fait tard, j'ai pas le temps de traduire en détail donc je te recopie ici ce que j'ai trouvé. Bonne chance à toi ;)
The quickest way to gain Norn Reputation Points is to kill the Facet dragons in Varajar Fells while having the quest The Path to Revelations active. The Facet dragons you must kill for the quest are counted as bosses in that area.
* In Hard Mode, if your party kills 250 foes prior to killing the bosses, you earn 450 points per boss killed, and if Hunt Rampage is active, your points are doubled. By killing the six bosses for this quest, gaining 450 rep each and double points if a Hunt Rampage is active, you can easily accumulate over 6k rep points a run (this will take approx 30-35 minutes). If less than 25 foes are killed prior to clearing the Facet Dragons, you will only receive 75 rep per boss (75 x 6 = 450 rep per run) and take about 7 minutes. While you could do approximately five runs in the same length of time as getting to 250 kills first, it would only yield 2,250 rep points.
* Note: When keeping track of the 250 kills to get 450 points for each boss, DO NOT go by the Hard Mode red icon kill counter in the Effects monitor; instead, go by the count being displayed in the chat area, as they are not the same (this applies with all rep point "hunting").
