ToME WikiRavenRed: Just a quick idea (which I may have already mentioned elsewhere). "Indestructible" Amulets and rings have a relatively minor utility now. If jewellery, however, was actually vulnerable to electrical attacks whilst the player is wearing it, it becomes an extremely valuable ego-type.
Artifacts should inherently be indestructible by mundane means, of course, but normal rings should be actually be destroyable (or damagable, reducing Pval).
This, of course, becomes another inventory management issue. Most people have left their ? of WoR when they leave to smite the fire hounds, this is just an extension of this principle...
2c worth and counting...
