in darkness falls, hibernia side, i noticed that the naburite drinker have such a small aggro range that you can move all the down to the cambions without getting aggro, not sure if it's just because of the aggro range (seems to be roughly 300) or if they aren't spaced enough to prevent people from walking through freely, another possible problem I saw is it's possible to just sprint through the naburite drinkers without having to fight them at all, they normally would deter people from doing that and getting through that easily, you can sprint through cambions as well without fighting them.
