One addition in this second edition (which would subsequently be extended to the whole system of rules in the later editions) is the appearance of Skills, mainly—but not exclusively—for thieves, murderers and affiliated professions. A character can learn skills by spending experience points, some talents are more expensive than others. Alongside the skills of "traditional" thieves are—for example—cooking skill. This system of skills (very popular in the roleplaying of the vintage, including in particular Chaosium's) diversifies the characters away from rigid traditional stereotypes.
