Looking through the latest news from Cubicle 7 we find that we have four charateristics confirmed; Weapon skill, Strength, Toughness and Initiative.
The only one I didn’t really expect to make a come back was Initiative. I felt that in WFRPv1 everything centered around having a high Initiative. It simply became a characteristic that was a catch-all for too many Tests.
Given that Initiative is back, my guess is that it will be paired with an Initiative Bonus. Much like SB and TB we will have IB, and initiative order in combat will be determined by a roll of 1d10 + IB.
A guess as good as any in these times of foggy news from Cubicle 7.
