With power over storm and sky, you can call down the wrath of the gods upon the world below.
Storm Burst (Sp): As a standard action, you can create a storm burst targeting any foe within 30 feet as a ranged touch attack. The storm burst deals 1d6 points of nonlethal damage + 1 point for every two cleric levels you possess. In addition, the target is buffeted by winds and rain, causing it to take a –2 penalty on attack rolls for 1 round. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Lightning Lord (Sp): At 8th level, you can call down a number of bolts of lightning per day equal to your cleric level. You can call down as many bolts as you want with a single standard action, but no creature can be the target of more than one bolt and no two targets can be more than 30 feet apart. This ability otherwise functions as call lightning.
