It's not called ally CoV.. but you know what I'm talking about. It's the ally buff they get at lvl 79. One of our lovely Dominators is a few days away from being able to learn this skill.... but where does this thing drop?
Like someone already said in another thread - the tricky thing is that there are several types of those Dinos, all with the same name. So the books/amulets have a drop chance of like 1/2000 to 1/3000, and only 1/5 of the mobs you kill actually are the type which can drop it...
I guess if you actually get such a book as a drop and would be willing to sell it, it would be **** easy to get a truckload of adena for it from large alliances...
Franz would more then likely be the most expensive one to get it at.
Probably around 1-2 billion give or take.
Dino Island hunting frankly sucks, the exp blows, the chance for top A weapon parts dropping is horrible, and the only reason people go there is to get those amulets/etc and even thats a crap shot.
