AGGEMAM said:FWIW on the ol' boards, back in august 2001 IIRC, there was an e-mail response from the Sage on this, he basically said that a twohanded is effectively an all-hand weapon in that you cannot wield more than one regardless of the number of arms you have, and that only if you do use all your hands wield said weapon would you gain the x1½ Strength modifier. The last bit is obviously a selfevident extrapolation of the first bit.
That contradicts the MM entry for Xill which says they can use two longbows.
