»Three is the highest fame level I'm aware of. 8 or 9 probably exists but I don't think it's anywhere near obtainable now.
Anyways, do every quest. There are pretty much no repeatable quests in Adoulin, besides one involving a coconut or something(I may be insane and such a quest might not exist). There's no fast way to get this fame compared to other areas.
Pretty sure it's only once per conquest update too. Fame might be able to go higher then 3 now, but it'll take forever to do.
