Rounds are exactly as you think, and are pretty much like how d20 systems do it.<br/><br/>1: Anything with a turn effect 'countsdown' on your turn. So, an effect with a "1 Turn" duration goes until your next action, essentially.<br/><br/>2: I don't see any rules for it, so until further notice, you can move up to your Speed as well as do an Instant, or spend your Instant for the turn to move twice your speed (basically PF rules)<br/><br/>3: I'll allow you to do a Dex+Atheletics check to do that because that is so very Princess and awesome that I desire to allow it.
