My favorite spell for DnD 5e is sacred flame. It’s time something like that happens in Pathfinder.
Casting Time 1 standard action
Components V, S, DF
Range close (25 ft. + 5 ft./2 levels)
Targets one creature
Saving Throw Reflex half; Spell Resistance yes
You channel the anger of your god into a violent explosion on a target in range. The target of the spell takes 1d6 points of fire damage plus 1d6 more fire damage for every two levels beyond 1st (to a maximum of 5d6 at 9th level).
