The long range bolt form is the smallest of forms and deals 1d6 points of damage and has a 100 ft. range increment. The medium range bolt form deals 1d8 points of damage, with a 60 ft. range increment, and the short range bolt form is the largest and heaviest form and deals 1d10 points of damage with a 20 ft. range increment. A soulbolt adds her Strength modifier to damage rolls when using the mind bolt in the short range form.
Emphasis mine. I did not find any reference to Strength modifier being used for long-range or medium-range forms of the soulbolt. My interpretation would be that it doesn't apply in those cases.
However, in my Hero Lab installation, it appears to be applying the Strength modifier to long-range and medium-range forms and Strength-and-a-half to the short-range form.
So my question is - am I reading this correctly? No Str modifier for long- or medium-range, only Str modifier (not 1.5 Str) to short-range?
