I feel my sorcerer PC should be able to cast infinite spells per round, but that's not allowed in the rules either.Balgus said:I feel that you should always be able to threaten the arean adjacent to you.
This is irrelevant. Improvised weapons have nothing to do with unarmed strikes or two-weapon fighting.The reason being you can always use an improvised weapon, granted you take a -4, a stick is still considered a weapon. heck- it is probably a better weapon than a sap.
Are you confusing the improvised weapon rule with the rule for doing lethal damage while unarmed? The only thing they have in common is that their to-hit penalties are equal (-4). That is a coincidence, not an indicator of an underlying connection.
