Repel Darkness

Your stoicism and courage seem to drive off darkness and shadow. For 1 minute, you suppress magical darkness effects of a rank equal to or lower than half your level rounded up within a 10-foot emanation. This doesn't provide light, but merely restores the area to its natural illumination level. You can Dismiss this aura.

If your horse is at least a mature animal companion, you can use Repel Darkness to cause the aura to emanate from your horse instead of you, as long as your horse is within 100 feet.
