Half-Orc Sorcerer

From publisher blurb:

While it is true that full-blooded orcs (and goblins) are unable to manipulate arcane energies, half-orcs, with their mixed heritage, have been known to manifest such abilities. However, because there are no schools of wizardry within the orcish lands, those that have the potential are left to piece the ability to cast magic together on their own. The end result is that these “sorcerers” are only able to master a few spells. These spells are fueled by the caster’s innate rage, and are often of a destructive nature.
