7th Interportal Tournament of HMM3-OFF: "Earth Magic"

An expert's wisdom can be given to one hero - Ruska...
P.S. indeed - the book cannot be bought. so you really can't get the flight on the map.

As far as I know, the "Roar of the Titans" gives the magic book to any hero, even one who didn't have a book before.

P.S. my result is 3/61.
