Ars Magica
An RPG set in ""Mythic Europe"" where hermetic magi work secretly in hidden covenants. The system is fairly simple: attribute + skill + 1d10¸ but the main rules are in the innovative magic system. The magic works by a ""noun + verb"" system. Magi have ratings in 10 ""Forms"" (nouns) and 5 ""Arts"" (verbs)¸ given in Latin as fits the setting. Any spell corresponds to a noun/verb combination (like ""Creo Ignem"" meaning ""Create Fire""). Resolving a spell means comparing (Form rating) + (Art rating) + 1d10 vs level of difficulty. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H. Kim"
