EDIT*****After much head banging, pain, and suffering, i *think* i figured out the skill system tree.Please let me know if im wrong.1. Combat Style : Strong SteelEach Combat style is devided by 5 trees or rather branches, which represent 4 possible combo sequences (lvl123+5)and 1 additional power up attack from level 4.That means if you have level 1 strong steel, the attributes or perks such as "cut at the jugular I"or "crushing blow I" will only affect the first combo sequence. Each attribute only affects it's level branch.Which means a level 1 strong steel + cut at the jugular I + crushing blow I will equal = +24 - +36 dmg +45% bleeding 2. Attributes : StrengthThe manual says: Note! All attribute related enhancements are cumulative.Which means strength stats from level 1 to level 5 all add up or stack.All level skills such as parry and vigor are also cumulative, meaning you keep both skills learned from level 2 and level 4.3: Signs: AardIm not quite sure about Signs, can someone please explain it to me?If i have a skill point in Aard level 1 and a skill point in student for a 180 degrees hit field,will i loose my student skill once i upgrade to Aard level2 meaning it will revert back to 90 degrees,or will 180 degree only apply to level 1 Aard strength ?If i upgrade Gust (Knockdown +25%) at level 2, will it stack on top of Gale(Knockdown +25%) at level 5for a total of +50% knockdown?I think sign intensity = more dmg for other signs, but how does intensity affect Aard, and what does +25% knockdown mean?When i use Aard level1 on Baargs they stay down and i can apply a finishing kill move, while other enemies get right up?
