I think you use the figures for half-elves:
quote:
Half-Orc Another example of a hybrid, half orcs are products of human and orc parents. Of a height similar to half elves, half orcs usually resemble their human parent enough to pass for a human in public. Their skin ranges from peach to olive to deep tan, and their hair can be blond, red, brown, black, gray, and shades in between. Half orcs can be members of the following classes: fighter, cleric, or thief. They can be multi classed in any two classes, but not three. Half orcs can be of any alignment.
Half Orc Standard
Racial Abilities (10)
Infravision, 60'

Half orc Penalties
In human societies, half orcs suffer a –2 reaction roll penalty.
If the player wishes to create his own customized half orc character, he can pick and choose from the list of orc abilities listed below. Abilities cost either 5 or 10 character points; refer to the descriptions below.
Active sense of smell (5): The character’s sense of smell is sensitive enough to give a +1 bonus to surprise rolls.
Acute taste (5): The character’s sense of taste is so sensitive he gains a +2 bonus to saving throws vs. imbibed poisons.
Attack bonus (5): +1 attack bonus with one weapon of the player’s choice.
Damage bonus (5): +1 damage bonus with one weapon of the player’s choice.
Fitness bonus (10): +1 bonus to the character’s Fitness subability score, due to his hardy heritage. The character’s Fitness score may be up to 5 points higher than his Health subability score.
Infravision (10): Infravision with a 60' range.
Mining Detection Abilities (5): A character with this skill is familiar with mining, tunneling and stonework. By concentrating for one round the character can:
Detect any grade or slope in the passage they are passing through, 1 on 1d4.
Detect new construction in stonework., 1–2 on 1d6.
Stamina bonus (10): +.1 bonus to the character’s Stamina subability score. The character’s Stamina score may be up to 5 points higher than his Muscle subability score.
Note that he will receive a -4 reaction roll from orcs on Tienna. He is considered a half-breed sub-orc no better than, and perhaps worse than, the humans and demi-humans.
