Factotum

"Where most adventurers focus on one field, you refused to choose. Others are forced to work alongside other adventurers to provide skills they lack. You, on the other hand, hold the keys to every field. You are a true polymath: a Factotum."

Factotum is a duet RPG (that is to say one player and one GM) in which our hero has studied every major field of adventuring skills at the same time. A jack-of-all-trades.
