Dawnstones

Dawnstone is the name given to a flint or obsidian dagger or hand-axe such as occasionally turns up in a barrow grave. They are relatively common, but enchanted stones are very rare indeed.

An enchanted Dawnstone has all the standard abilities of a magical weapon. In addition, it casts a permanent Zone of Sanctuary spell around the bearer, which will move as the bearer of the stone moves. If any other Zone spell touches or occupies the same area, it will be dispelled, and that cast by the stone will be disabled briefly.
