Ignite the Sun

The fires of creation become yours to control. You create a miniature sun in a within 500 feet. A creature takes |options:area-damage] damage any time it's in the miniature sun, with a save against your class DC. A creature can take this damage no more than once per round. The sun sheds bright light in a (and dim light for another 500 feet); this is sunlight for creatures with a particular vulnerability to sunlight.

The sun lasts until the end of your next turn, but you can Sustain it up to 1 minute. The first time you Sustain the impulse each round, you can choose to increase the size of the sun's burst by 5 feet, then make it Fly up to 30 feet. The sun can move through creatures, damaging them as described above.

The sun continually channels fire into you and your allies. You and each of your allies within the sun's light deal an additional ] damage with all Strikes, spells that deal fire damage, and impulses that deal fire damage (except for Ignite the Sun itself). These aren't cumulative with multiple suns.
