Orcs Of Maras-Dantia (trying to create a campaign in the Orcs:First 
Blood world by Stan Nicolls)

Learn horsemanship at 50% cost.
Learn military scientist at 75% cost.
Suffer ?5% in bright daylight
75ft dark-vision
Only learn elemental magics
Only learn general spells and rituals.
DQ stats  +1 PS, +1 MD, +2 FAT, +1 END, -2 MA, -2 WP, -1 AG
Must make concentration check to escape any combat where they have 
been struck a blow.
Ambidextrous if D5 is > D 10 roll, can choose handedness if not as 
equally likely left or right-handed
Have ?5 magic resistance.
Heal as though they have at least 21 END with regard to Fat and End 
recovery not diseases and poisons or anything else.

Trying to keep it at the standard Orc of x0.9, dont know if I have 
over-powered it?

On another issue DQ is my game of choice but the race descriptions 
and variation in abilitys needs a litle work to bring them to life I 
think.
