Critical Chance Affect Dagger skills ?

Does "Critical Chance"(passive skill) increase Succes Rate from dagger skills like deadly blow,mortal blow ?

yes. thats why so many daggers go light elf.

buffs do not affect dagger skill land rates apart from Mortal Strike ( or w/e the self buff name is)

hmm so success blow = high critical (stat) ???

S.a focus(kris,ds) affect land rate of dager skills ?

no. only the passive skill and the Dex factor of your stats affects your ability to land dagger skills.

I dont think they do.
Only dex and mortal strike do.
This is what i know.
Spudnik which passive skill are you reffering to?

critical chance. light elfs get this. dark efls get critical power.

Light Elves get critical chance,d elves critical power and humen both.
Anyway as i said i dont think critical increases the success of skills but only ciritical rate of simple hits.

When C3 hit, Critical Chance stopped affecting dagger speicals.

MooMoo is correct. "So many people" say the PW is gimp precisely because their stabs are weak (compared to the other two) and not much more frequent than those of the AW.

so if i put a dye +4 dex ... the land rate of dagger skills will increased ?

Yes
