With proficiency in this skill category, you are able to use your left hand equally well as you right hand if you are right handed (or vice versa if you are left-handed). If you wish to use a weapon in your off hand then you need the ambidexterity skill of at least the level of the weapon, and as with other skills, lower ranks must be learnt before higher ranks. With AMBI I you can use any weapon from Bladed I, Hafted I or Thrown I in your off hand. You may also use either hand as your spell-casting hand. With AMBI II you can use any weapon from Bladed I/II, Hafted I/II or Thrown I/II. AMBI III allows any size III or smaller weapon to be used in your off hand whilst AMBI IV allows you to use from Bladed IV, Hafted IV or Pole I/II in your off hand providing Strength IV is also known. Crossbows can also be used with either hand with this skill.
