Minstrel is a playable character class.

Beautiful songs of a Minstrel can do miracles: make the weak in body strong, give the weak in spirit courage, or even pacify enemies. In any company with a minstrel it is always more fun, even most evil enemies are not so scary. With the help of songs, they can manipulate the auras of opponents, turn them into stone, or even take away their vitality.
