Unless I am mistaken, Glancing blows can proc this effect. As-well-as, Glancing blows can happen on any fourth swing of two-handed weapons and under certain circumstances, bastard swords and dwarven waraxes, regardless of the attack roll. Therefor, it is possible to proc this effect on a glancing blow with a roll of 1. ShoeMaker 13:39, January 24, 2012 (EST)
Yea though it's a bit more complex then that. Glancing blows also get their own attack rolls, and also always miss on a 1. They also only proc special effects at a very low percentage based on feats/enhancements. So while you can roll a on 1 your main attack and get a glancing blow hit.. Chance of procing a ls on that is infintessimal.
Though i think all our pages just list average/20, so it might be better to leave it, for more accurate comparison. Less they all get updated.
