Genetics Guide: Thunderstruck

Thunderstruck creates branching markings similar to a lightning bolt.

Thunderstruck must appear as at least one branching marking approximately the size of the example below. This marking may have two colours: one natural and one semi-saturated. One must be the lightning bolt itself, but the other may be a gradient beneath the mark. This gradient is optional. Both colours need to be solid unless affected by a colour mod.
