Ambrus, because init was dropped then resumed with a two-round intermission, it looks to me that you're befuddled about whether Maelicent missed actions. I would go so far as to say rightfully so. We will therefore even the slate by saying that the PC spent one round extricating himself from beneath the spider and collecting his dropped weapon, and a second round casting about, searching the spider from under which he crawled. Looking at Maelicent's RG sheet...no ranks in search and +0 Int modifier. Goodness. Maelicent searched the spider but, finding nothing of appreciative interest or worth, he would've continued on precisely as you and I wrote him, which was 120 feet out into the byway to chase after the fleeing spider. More precisely, the search of the wolf spider nets Maelicent the knowledge that the beast is large in size (and boy did you all benefit from me forgetting that every time a PC moves in to attack a creature one size category larger than yourself that it's supposed to draw an AoO from the foe because of threatened squares), has a black chitinous exoskeleton, a wolf head where a normal spider's head ought to be, and really no other interesting markings of discernment. Had it not been for the aberration's strange head and ability to speak, the spider could have been a simple large spider in any forest in the land.
With this information in hand, you may find yourself wanting to alter your post in which you state:
OOC: I'm going to assume that Maelicent never made it past the bar since he never had reason to get closer than that to shoot the third spider-thing before it died.
Because, in point of fact, that is not how it played out. Should you have any questions, I will be around today to reply. We are still on initiative. Because of Traven's death, the combat environment changed so radically that by the middle of Encounter 2, Round 3 I called for Brakkus and Maelicent to clarify intent before continuining with the remainder of the round. I've got a salient post from Brakkus. I need you to please clarify what you want your PC to do, given that he is standing in the byway, bow drawn, just after the spider has been slain. After I receive that info from you, I will go ahead and post a DM's reply for the remainder of Round 3.
If I have posts from everyone for Round 4, I can maybe also do Round 4 today. We'll see on that, though.
