Can the playtested Magus use a one-handed weapon in two hands when he attacks with his two-weapon-fighting ability with spells and thus get two-handed damage? Or does he literally have to have a free hand at all times, even when he's not casting?
It has to be free during the round in which he casts.If he doesn't cast that round, he can 2 hand a weapon.
OK, thanks for the help.
Two-weapon fighting and two-handed weapon fighting are mutually exclusive.
With the regard of the Magus, or holding two separate weapons, I agree. As a cool fact though, you actually can do it with a 2h weapon and unarmed strikes -- if you have a level of Monk to determine that you can strike with any limb at no penalty and never as an offhand. You 2h-chop and kick, pretty much. I suppose I was trying to apply that theory to the casting.
