Ok, so I finally found myself some alchemical handwraps. When I put them on (as blanks), I lose +7 to-hit. Yup, I go from +40 to +33.
I fiddled around with gear, can't seem to understand why this is, for example, if I take off my epic spectrals (+4), I go down to +31, if I put them back, +35. But it's still not anywhere near the +40 I get from any other +5 wraps. Even naked, I don't get as much bonus to-hit with alchemical wraps than normal wraps.
I'm gonna take a wild guess here and suppose the enhancement is not taken into account (again), and that the flurry of blows bonus is somehow not calculated, even if i AM centered.
Toss monks a bone, they've been broken for more than 3 years now...
EDIT: Seems it's the enchantment bonus that's not being apply, and a competence bonus that's not stacking properly (Stacking with what if the "+" isn't used in the first? No idea, but it ain't applied right)
