kensai wep. mastery crits

[deus_ex]

so when you get kensai wep mastery 3 your crit. range is increased by 1 for that wep. how does that stack with the feat improved crit? is it (<original crit range)+1)x2 or (<original crit. range>x2)+1? specifically i'm working with dwarven axes.

its apllied after any other effect, though basicly it doesnt matter as imp crit doesnt actually double it as in x2, it just adds the base critrange again

DA is 20/x3, so 1 range
imp crit adds that same amount again, 1+1=2 (19-20)
kensai adds another 1 to that, 2+1=3 (18-20)

for a rapier its 18-20, so 3 range
imp crit adds that same amount again, 3+3=6 (15-20)
kensai adds 1, so 6+1=7 (14-20)

its the same as damage multiplyer for crits: on a x3 weapon your damage doesnt get trippled, the dives just get rolled 2 additional times
