First off, yes I missed the readied action, and the aoo hit luckily from your description(Surprised. I'd expect the bats to have mobility if they have flyby attack) Anyway the tl;dr of this post is The bat is either in melee range of rose and rose gets to attack before it goes or it provoked an aoo from both rose and the astral construct and I'm not sure which is the case.<br/><br/>Are we using some sort of simultaneous actions when acting on the same initiative or just sort of doing that for convienence? Normally readied actions work like so<div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">Your initiative result changes. For the rest of the encounter, your initiative result is the count on which you took the readied action, and <strong>you act immediately ahead of the character whose action triggered your readied action.</strong> </blockquote><div class="quotefooter"><div class="botslice_quote"></div></div>So I'd have the same init number as the bat I stabbed, but go before him, allowing me to ready an attack and strike him as he gets close, and still going before him on my next turn allowing me to full attack if he's still within melee range.<br/><br/>Average maneuvrability means next turn the bat will have to provoke an aoo from both rose and the astral construct if it didn't land this turn or stall since it can only turn 45 degrees for every 5 feet forward it moves, and moving even 5 feet forward will put it in range of the astral construct(It could than land and not provoke an aoo from the astral construct I guess and since only taking a 5 foot wouldn't provoke one from rose either) but it probably had no problem satisfying the minimum speed getting close to rose this turn and so definately no aoo yet if it's still in melee range of rose. If it's not in melee range both rose and astral construct will get an aoo.<br/><br/>Flight with less than good maneuvrability is really inconvienent in combat.
