From publisher blurb:
Climb Every Mountain!
101 Hill and Mountain Spells gives players a mountain range of ways to use spells to go over, under or through these mainstays of every fantasy world. In addition, GMs will find a dwarves’ mine full of new and unexpected spells for NPC friends and foes to aid or challenge players.
What goes on in those secluded hills? What’s making those terrible noises in the caverns of the mountain? The creatures living in these places have developed their own spells over the ages, and the adventurers exploring these forbidding regions are always looking for new magic to help them overcome those challenges. Need a better way around that pass? How about turning everyone in the party into a wyvern?
