Rock & Rule: The Spellbook of Gristlegrim's Dwarves

From publisher blurb: This is a gamemaster supplement intended for Deluxe Tunnels & Trolls (although it will work with any version of the rules). Ken St Andre has decided that each of the kindred (Dwarves, Elves, Fairies, Trolls, etc) should have its own spell book, and this is the first of them. Dwarven wizards are rare, but when you find one these are the spells he's very likely to know. Dwarven magic is just a little HARDER than human magic.
