All eq is wearable no matter what race you are, but one race has bonus, for example
instead
The spidery language of magic comes out of your mouth.
A warm wave of magic flows through your hands as you perceive that..
.. this object, an amulet covered with elven runes, is armor,
and can be referred to as 'elven amulet runes'.
It is of 27th level, weighs 1 pound, and is worth 45 gold.
You can wear it around your neck.
It glows with a soft light and hums faintly.
It cannot be used by those of darkened soul.
It is fireproof and resists corrosion.
It is designed to be used by elves. (it would be better 'It is enchanted to be used by elves')
Armor class bonus: 7 vs pierce, 7 vs bash, 7 vs slash, and 7 vs magic.
When worn, it
modifies fortitude save by 5

PS. But it looks like it would take considerable changes in how program works. Anyway one thing can be done- instead designed for elves - enchanted for elves, that is simple to change. I dont see how design changes can stop human from wearing one amulet, but enchantment can do it.
