Lets say I take the Archlord Greater Discipline option: "When selecting a single Discipline, Greater Classes may increase each Ability listed in the Discipline by 1, doubling the point costs of the Trait." With a discipline like Berserker: "Increase Strength 2, Increase Toughness 1, Increase Movement 1, Decrease Martial 1, Decrease Ranged 1, Decrease Defense 1." How do traits like Berserker, which contain both increases and decreases interact with Greater Discipline?
I can see 3 answers:
Greater Discipline would increase the value of each increase and decrease from Berserker. Resulting in an Increase Strength 3, Toughness 2, Movement 2, and decrease Martial 2, Ranged 2, and Defense 2?
Greater Discipline would increase only the values of each increase from Berserker. Resulting in an increase Strength 3, Toughness 2, Movement 2, and decrease Martial 1, Ranged 1, and Defense 1.
Greater Discipline would increase each value in a positive way. Resulting in an increase Strength 3, Toughness 2, Movement 2, and decrease martial 0, ranged 0, and defense 0.
Which of these answers is correct? Thank you kindly for any clarifications.
