This is a COMPLETLEY new idea which has never before been a part of any game what so ever...

How about the ability to tweak "standard" weapons, armors and so on with for instance gems and stones that posess certain abilities? Bloodstones, moonstones, rubys call them what you want.

Let's look at weapons for example.
There could be different types of weapons. Keep the once that are allready in the game and add slots to standard weapons, like 1-5 slots or something. In these slots you can place gems that you find and buy around the world, and they give your weapons special abilities, and if you combine the right ones it will be even more powerful? Which ones to combine would of course be a secret (for a while.. ).

After you've created your own weapon it cannot be changed, so if you sell it, it would still look the same.

This would give the gears an even more interesting part of the game.

What do you think?
