Strength +4, To hit +7, Base damage 11B. Strength +3, To hit +6, Base damage 10 or 20Versus AC 18:A. Hit probability 50% (needs to roll 11) = expected damage 11x0,5=5,5B. Hit probability 45% (needs to roll 12) so does not use featActual hit probability 45% x 10 = expected damage 10x0,45=4,5Winner A by one point (much as expected)Versus AC 12:A. Hit probability 80% (needs to roll 5) = expected damage 11x0,8=8,8B. Hit probability 75% (needs to roll 6) so uses the featActual hit probability 50% x 20 = expected damage 10Winner B by not much more than one point.So far the feat seems balanced or underpowered even.But this does not take into consideration the numerous ways of boosting your GWM usage.So let's compute vs AC 12 with advantage, shall we?Versus AC 12 with advantage:A. Hit probability 96% (needs to roll 5 once) = expected damage 11x0,96=10,56B. Hit probability 9375% (needs to roll 6 once) so uses the featActual hit probability 75% x 20 = expected damage 15Winner B by four and a half point, or over +40% damage.Before we move over to conclusions, I'm posting this so you can check so I haven't made a mistake, or suggest why another set of comparison points would improve the analysis.</blockquote>
