Ambidextrous
Merit · 1 pt
You have a high degree of off-hand dexterity and can perform tasks with the “wrong” hand at no penalty. The rules for taking multiple actions still apply, but you do not suffer a difficulty penalty if you use two weapons or are forced to use your off hand.
Also in BoS p. 37 — text differs from V20 (71%)
The hemispheres of your brain are so attuned that you can use both hands with equal dexterity. In game terms, you do not suffer a higher difficulty if you use two weapons or perform some task with your off-hand. The normal rules for performing multiple actions still apply (see Mage 20, p. 388-389), but coordination between the left and right sides of your body is no problem at all.
