If playing with the Adventurer class, the trophy will have a 100% chance of unlocking any class & race, which may be the Halfling or any other race not already unlocked. If playing with another class than the Adventurer, the trophy will have a 50% chance of levelling that class up, and a 50% chance of unlocking a new class & race.
