Only certain people have the ability to do magyk. Magykal ability is not transferred through genes or exposure to anything (although that may have some near-magykal effects). Instead, the assignment of Magykal ability is completely random.
The ratio of people in a species that have magykal potential is known as The Magykal Potency Ratio.
The Ratio, according to surveys done by The High Council Department of Magykal and Natural Abilities is as follows:
Humans - 1 in every 132 or 0.76% chance
High Elves - 1 in every 7 or 14.29% chance
Forest Elves - 1 in every 23 or 4.35% chance
River Elves - 1 in every 94 or 1.06% chance
Drow Elves - 1 in every 115 or 0.87% chance
Dwarves - 1 in every 379 or 0.26% chance
Gnomes - 1 in every 638 or 0.16% chance
Orcs - 1 in every 203 or 0.49% chance
Goblins - 1 in every 197 or 0.5% chance
Halflings - 1 in every 267 0.37% chance
- Please note that this list only includes the major races. Other races have their potency (if any) on their own page.
^For crossbreeds, the ratio is completely unpredictable, but is generally somewhere in between the two parent races' ratios.
