You are able to easily cast spells while mounted.
Prerequisite(s): Ride 4 ranks
Benefit: You never need to make concentration checks to cast a spell due to vigorous motion caused by riding a moving mount.
Normal: Normally you must succeed at a concentration check (DC 10 + the level of the spell) or lose the spell when you attempt to cast a spell while riding a moving mount.
