how to sitesearch effective ?

[Saxon]

Hmm, that is good to know. I did not realize that each magic site had a type, which determined what path of magic was needed to find it. I thought that it was determined by which gems were produced at the site. Thanks for letting us know and sorry for stating that spells like Gnome Lore would find all sites producing earth gems.

As others have said, a spell like Gnome Lore can be used to search two provinces in two turns, while a moving searcher can only search one. This is a big advantage, especially as the sites are worth more, the earlier you find them.
