Again, thank you for your accurate response.
But this brings me another misunderstanding.
I thought the bonuses on attacks rolls were as follows:
+18 Base Flurry bonus
+12 Wisdom modifier
+ 1 Weapon Focus
-5 Deadly Aim
+5 Bow bonus
+2 Bracers of Archery, greater
+1 Point Blank Shot
For a total of 34.
But with your correction, the correct calculation is the following one.
+18 Base Flurry bonus
+12 Wisdom modifier
+ 1 Weapon Focus
-6 Deadly Aim
+5 Bow bonus
+2 Bracers of Archery, greater
+1 Point Blank Shot
For a total of 33.
So I am again missing something, what is it please ?
