You absolutely cannot get Listen higher than 127 by any means.
Never said otherwise, I wasn't sure how high it could get so I made mine go to 150 to be safe.
Also, the chart I have handles the halving properly already.
Again, I don't think anyone said or implied otherwise. I know I didn't and I think Funky was just trying to make sure that I had done mine right too. Thanks for the link, didn't know you had those charts, I thought funky was referring to the chart in the LL rule change book... That only had it for 50% and I wanted to see it over the whole range (again, didn't know your other chart existed).
Craft Armor gives you +1 AC per 40 ranks. Craft Weapon gives you +1 AB per 40 ranks (only with weapons).
