Wolf Girl has 45 STR, and Claws built as 1d6K Penetrating. That’s 12DCs at +1/2, which works out to 3d6K Pen with STR. (And yes, she bought Pen for the full STR+HKA, not just the HKA part.)
She wants to do a Move-By with 20m of Running.
Halving her STR rounds to 23, which is 5 DCs, which at +1/2 Adv comes out to 1d6K Pen.
Adding the Claws back in brings us back up to 9 DCs, 2d6K Pen. (The 1d6 from the HKA is not halved, right?)
20m of Running adds +2d6, which is really +2 DCs because of the Advantage, so that gets us back up to 11 DCs, 2d6+1 K, Pen?
Wolf-Girl takes 1/3 of that as Normal Damage, which works out to 4d6 Normal.
Does that all look about right? I’ll be honest in 30+ years of playing Hero this is the one area that’s still a little fuzzy to me. I tend to handwave it a bit in game, but I have time to think this one out between sessions. Thanks,
