About Sales

I have more than 100 books, armors, weapons, and materials
I want to sell all of them.
Why i can sell only 3 items everytime?

Expand your sell window with PoF.

This is the limit of the NonDwarf sell shop.... Dwarfs can have up to four slots at a time to sell.

Expand your sell window with PoF.

I didn't know Prophecy of Fire could expand your sell window :P
Use Proof of Catching Fish's to expand your sell slots. Though you'll never get more than five additional slots (IIRC)
Also, prioritize your spellbooks. Any SB that's for a sub 40 character sell to the NPC. Rare SB's will sell from anywhere from 100k-500k depending on the SB.

selling books is a pain, I have about 300 books in my WH's.
you will have to learn what books are usefull and will sell, and what books wont. vendor the useless books.

Ah sure im lazy , but the fish thingy should just be called proof of fish.

For the proofs, do I just buy one and hand it in to a fishing manager person?

And you need to be lvl 40 to get +1 slot. And it costs 10k of those proofs.

I think +1 is 4k proofs, and +2 is 8k proofs. i may be misstaken tho

It's 10k for +1, unless they changed it in C5.

hmm ok. I know inventory slots are 4k/8k I assumed its the same with store slots, but I guess you are right about 10k :)
