It's not really 50 different magic items. Many of the items are variants on the theme. Also, items seem really underpriced, which could cause game balance issues. And some items just seem to fall flat when you do the math. Universal Treasure Map is only 2,000 gp, but can be used once a day to locate the nearest treasure horde of at least 1,000 gp value! The problem is that it only has a 300 ft range. That's only a football field. Generally, by the time you are that close, you probably already now where the treasure is! Still, a lot of good ideas here that with minor tweeking can add some variety to treasure. And the price is right.
