    Electricity, 120ft line, which is 40M length. Reflex half, SR applies.

    Hits for 1d6 electrical damage/level to 10d6 max.

//:: Spell Effects Applied / Notes

    Taken some of Bioware's code for this - IE, to make sure they are in the
    line.

    We, however, use local objects, which should be faster.
