Benefit

You gain a +4 bonus on opposed Charisma checks when you attempt to control an elemental vessel. If you use lightning reins or a wheel of wind and water (depending on the nature of the vessel you are attempting to pilot), your bonus increases to +10. If you fail the opposed Charisma check, the vessel continues its current motion, though you can try again the following round. Even characters not of House Orien or House Lyrandar sometimes take this feat, in an effort to pilot airships and earth sleds without the auspices of the dragonmarked houses.
