I cant seem to find the answer but I was doing a alt character where I wanted to do all quests that give reputation within 5 levels so no reduction occurs. Pretty much just to see how much reputation u get from each faction by questing but I’ve already failed it I think.
In Silverpine I did the quest Wild Hearts before I did the pre quest for it titled “Lost Deathstalkers”. On completion of the Wild Hearts quest, Questie automatically completed Lost Deathstalkers and I never took note to see if the quest Lost Deathstalkers automatically added the reputation as it gives 25 to Undercity.
Its not a huge deal since its early in the game but I think I bit off more then I can chew on this challenge especially if I have to be aware of every quest if they have a pre quest available that gives reputation.
