Is it a maneuver or an action to pick up a weapon after a character has been disarmed? If a character spends 3 advantage in melee to disarm his opponent, can his opponent just spend a maneuver to pick it back up and then still take an attack action the next turn? If so, wouldn't it be better to just spend the advantage on a crit, since most of the melee weapons need 3 advantage or less?
Thanks in advance!
