Thanks for helping out, I was getting a bit overwhelmed by all that needs to be done, hehe
I think it would be best to list the items in a table with distinct columns, ex of columns titles: Icon, Item or Name, Description, Purpose (in the cells, you specify "unlocks x power" or "needed for x quest", etc). It would be neater imo.
Instead of explaining each power, you could add an link to the "Item Powers" section the powers page. It would make the table less clunky, plus you wouldn't have to explain the powers twice.
