Could someone smart explain me slowly how the library quest works? As in how is he giving out the reward, based on what? Wich rarity books should I get, what quest should I do, what if he asks for different rarity books, how much should I spend on how many books vs rarity and so on...my head is spinning...

If there is a guide somewhere and I didn't find it, sorry and point me to it?

His rewards are based on rarity. If you are asked for two rare books, you'll get two rare rewards. If he wants a common, normal, and rare, that tends to average out to a normal. When he is Weekend Quest, you also have a chance of getting a retired book as well.

I tend to spend based on how many books he asks for. If it's only one, depending on rarity, I don't spend more than 5K (unless it's a rare book). Two, it's about 10-15K. And three usually no more than 25K. Do what you feel comfortable with.

Thanks a million millions! :)

You're welcome a million millions :)

- Make sure to check out the stickied thread in each section of the forums as this can help you out. There are a couple of guides listed in the stickied topic here. One of the guides is outdated now, but some of the information might still help you, the other listed there will show you the rarity of items and such.

Since these questions can be answered in those places I'm going to lock this topic. Happy questing!
