*'''Simultaneous Actions''' are reactions to a stimulous and can only be applied to that particualar set of stimuli. These represnt reactions (attack of opportunity), side by side actions (the free attack gained on a successful trip), and occasionally abortive moves or tracing actions (savessuch as the movement associated with Dodge or Parry Defense). Unless stated otherwise, a simultaneous action may only be taken once per turn and is essentially a swift action. Once a simultaneous action is taken another one can not be taken until the next round.
