High Elves - Artifact control (bad name) - Automatic.

When using Wands, Staves and even scrolls, the elves over the years have learned to channel the powers of these items very carefully. Learning to preserve the energies of artifacts while still getting the full effects takes much practice but when done properly it is possible to preserve the 'charge' of the object while still succeeding in casting. Obviously, would not work 100% when well practiced but certainly stop the rapid degredation of wands and staves. Perhaps its a bit silly with scrolls, but a small chance of preserving the scroll would be nice. Can even add flashy echoes!!!
