Karmic Twin( Oriental Adventures, p. 64)
You are descended from Bayushi, the first Scorpion, whose love for his daughter proved his final downfall.
You get a +2 bonus on all Charisma-based skill checks and Charisma checks. You have a karmic tie to another character. You may detect the direction of this character if he or she is alive, on the same plane, and you succeed at an Intuit Direction check against DC 15 (or a Wisdom check if you do not have the skill). A failure on this check gives no information. You may retry once per round as a standard action.
The character to whom you have this karmic connection may be another player character or an NPC under control of the DM, but he or she must also have the Karmic Twin ancestor feat.
