Book of Giants?

First there's the Secret Book of Giants for overenchanting items. This is not what I'm asking about.

Book of Giants or quest item with similar name. You double click on it and it becomes other items. I've seen this player sell shops.

Question: What quest gives this reward and what items do you get when you double click on it. Does it give out the Secret Book of Giants related to overenchanting skills? Thanks much.

hmm not really sure but I think you may be referring to the quest items that drop when doing the Exploration of Giants Cave quests. Maybe check out the walkthrough for that one at stratics and see.

there is a book you get from giran store, is that the one you talking about?

The book looks like the necro spellbooks. But it's a quest item. You double click on it to reveal items like the ToI papy quests.

I'll check stratics and the GC quests. Thanks for the suggestion.

That's second part of the GC quest.
First gives anchent papiruce shaped pages of different colors.
