[1.2.319] [ENG] Adventurer skill revamps

Doesn't
(220 x 1.5) + (220 x 1.5) = 440 x 1.5

and
(170 x 1.5) + (170 x 1.5) + (170 x 1.5) = 510 x 1.5 ?

There is no difference between applying the multiplier to the individual hits and applying the multiplier to the total damage...?

On a side note, can Blazing Armour block 1/1 attacks?

An individual hit is one hit. I doubt Final Attack merely adds more damage to your hits as it still has its own hit animation.
