Tunnels and Trolls Supplement

A rules supplement for the first through third editions of a fantasy role-playing game, presenting new rules, alternate procedures, and clarifications. Some of the material is later incorporated into the fourth edition. The original 1975 pamphlet contains nine pages; a 1976 edition adds four pages of worldbuilding advice and spell clarifications.
