These are a set of magic tools to make your RPM experience feel more like the fanstasy: magic tools to strengthen casting. RPM already has one method to increase the power of a mage via items: grimoires. I hope that these items will fit in with them nicely.
Cost: These tools have costs and weights given for them. When I created them, I had a TL3 to TL4 world in mind, and assumed that wizards were wealthy. If you port these tools to a TL8 world, you can increase the cost if you wish, or simply keep them the same. You can set the costs at whatever you want -- though I suggest you use multipliers than doing completely new costs.
