Previous research by Mythica Demonwright and Bremen Demonwright provided the initial recharging and damage data. It might have been updated since then.

- Recharging some of those is not worth it, for example you can cast Collatrap's Instant Pickling Stick to get more wands of pickling. Most artifacts are also sold rather cheaply, whereas purple mineral powder can be difficult and expensive to procure.
For what they do, until someone gets around to adding the artifacts to the wiki, see: http://www.gunde.de/discworld/sekiri/artifacts.html
- The ring of recall can transport you in greater trouble than you were in and it needs some time before you can use it again. Having more than one is prudent.
