Magically Uninclined (3.5e Trait)
From D&D Wiki
You find spellcasters despicable in nature.
Benefit: Once per day you can activate smite magic. This acts the same as smite evil except it works against a caster, magical beast, or spell-like casting creature. You may use Int or Wis to replace Cha for this ability.
Drawback: -2 Cha skill checks against spell casters.
Roleplaying Ideas: You loath the existence of spellcasters and the air they breath. Though you have no disregards using their items they create, you hate the caster in essence. You will always disagree with a caster, choosing no casters in any social interaction. If in combat, you will always seek a way to help the caster last.
