fire bow build

I would like to roll a scion with a bow using fire element. Does anyone have a good build or point me in the right way to find one

There aren't many Flame Arrow guides. One for ranger and one fire arrow trapper for shadow afaik.
Both are proliferation builds that will no longer work with the upcoming 2.0 expansion.

That leaves Explosive Arrow if you want to do fire damage. There are several EA builds linked in the shadow builds list, some of them might be changeable to start as scion.
