Ambidexterity

Ambidexterity(Warrior or Rogue, 2)
Ability: Dexterity
Modifier: Special
Characters with this proficiency are skilled with the use of either hand. Any character that wants to have the Ambidexterity proficiency must have at least an unmodified Dexterity of 16, in addition to spending 2 proficiency slots to acquire. This trait carries over into training; so that the PC can use weapons, bear a shield, and perform acts of strength equally well with the right or left hand. The normal penalties for using two weapons is ‐2 for the main hand and ‐4 for the off‐hand; but with this proficiency there is no penalty for the first hand, and only a ‐2 penalty for off‐hand use. This proficiency is naturally helpful with the Two Weapon fighting style (see Fighting Styles above), as it reduces all penalties for off‐hand use.
