You are one of the generation of dwarf twins born after Moradin's Thunder Blessing in the Year of Thunder.

Prerequisites: Dwarf but no duergar

Benefit: You have a twin brother or sister (fraternal or identical). If your twin is alive and on the same plane, you may attempt a DC 20 Insight check to sense his or her direction. If successful, you can note your twin's direction with a move action any time you take the time to do so during the next hour. You can retry this check once per hour.

You also ground your twin, while your twin is within 4.5m of you. You may reduce damage your twin takes by up to 5 and take the damage yourself, this damage ignores resistances and other reductions.

You receive +1 CL with air, lightning and thunder spells.

Finally, you receive 5 points of resistance against lightning and sonic damage.
