To avoid such troubles, I would disallow taking a full-round action on a surprise round at all. If you catch your enemies by surprise, you have to act quickly, otherwise the surprise is forfeit...likuidice said:so an invisible assailant, who started a coup de grace action during the surprise round, would have to use a second round to finish it, or an invisible rogue with whirlwind attack would: start the action in surprise round, breaking invisibility, then complete the action in the normal round, possibly having his opponents beat his initiative and just move back out of reach?
