ok so you want to make the game realistichow about falling damage
and each race can fall different lehgths before they get hurt E.G
the KRAN would take more damage from long falls (because they are huge ond not very dextrous)
where as the ENKIDUKAI would take less damage becaouse they are cats(and cats always land on their feet

)
or you can tinker with it all you want but its an idea
like the fall damage, and height you can fall before you take damage can be based on maybe agilty, race,armour equipped, things like that
