Could somebody check my math regarding this Ex Power
I have a 3 level fighter with strength 20
At 3rd level, when a two-handed fighter makes a single attack (with the attack action or a charge) with a two-handed weapon, he adds double his Strength bonus on damage rolls.
I have a 3 level fighter with strength 20
So the damaage with a Two handed great sword would be
2d6 + 5 (str) + 5 (Double) +5 (x1.5 two handed weapon) = 2d6+15?
OR is it 2d6 + 5 (str) + 5 (Double) +2 (x1.5 two handed weapon from the natural str bonus) = 2d6 +12
