Hold out a lit torch and a Drakeling lands on your shoulder. It then banks the experience you earn: craft, harvest or fight to fill its bar, and when the bar is full it lets you feed it once. After each feed it picks a different kind of activity and you fill the bar again, so keep all three going rather than specialising. Stop earning for ninety seconds and it loses progress, and knocking it off your shoulder costs effectiveness, so leave it there until it is done.
