Hello I just bought an archery brace and I wonder, does it affect you archery skill?
It may or may not. I dont think anyone is privvy to giving out the hidden code-side bonuses or detriments on items.
I.e. some tools are rumored to help your skill in things, but then again using a tool would LOGICALLY be better then using your bare hands (in applying situations). so if an archery brace would logically assist in real archery, there is a chance it may in game. Just try with and without, and let your chracter learn for himself :)
