Jack of Trades in Frydheld Sector (Classic Traveller)
Jack of Trades allows player characters to attempt a throw as if they had -0 in a skill. Their Jack of Trades levels confers a bonus to the roll as appropriate to the skill being tested: Jack of Trades-2 would give a +2 bonus to a Pilot throw, a +4 bonus to an Engineering roll.
Jack of Trades is not a substitute for professional training and can not be relied upon for a steady career.
For each level of Jack of Trades a player can burn that level to get a +2 bonus to roll. Once a level of Jack of Trades is burnt the skill is treated at its reduced value until the next session. If Jack of Trades is burnt to 0 player characters may no longer use it as a substitute for skills until the next session.
