This isn't the first time people have been lost whilst seeking this quest, it's fairly confusing when one must hunt through a collection of quests to find one with pre-reqs of its own hidden at the bottom of a scroll bar. Assuming of course it's even actually already appeared in the Quest Book.

It's also a bit strange that while the lowest tier in the Explorer skilltree isn't available until level 26 the quest to 'use a Manuscript on an Explorer' can show up as early as 16. The only explanation I can think of is that it serves as a heads up (for 10 levels) that Books can be used on a number of things.

As an aside these quests to spend books seem no less poorly thought out than they did a few days ago when they arrived, there are much more economical ways to skill a specialist in a manner that suits a player than the path presented in the quests.
Yes the quest should be changed so you only use 5 manus, and 5 tomes on each geologist and each exporer. Now you have to use book s that you will later want to reclaime, and lose 50% of them or have to use gems, it sucks that the only way you can solve these quest is by doing somehing you will later regret.
