Coleman does not miss the opportunity to punish the hound as it disengages from the machinery. It does, however, get the opportunity to fight back and barely manages to score a bite on the Dwarf. It does 7 hp damage and executes a trip maneuver, dragging Coleman to the ground, and knocking him prone.
OOC: While we are waiting, @NotTVsFrank may be interested in knowing that Medio can craft, with Bonnie’s help (she knows Invisibility) an Elixir of Hiding for only 125gp in materials. It gives Stealth+10 for an hour.
(I’m reading up on Wondrous Items now that Medio has the corresponding item creation feat.)
The feat says “when targeted”, so going with the spirit of the rule Dory would have no way of knowing if it would have hit or not, and in a tabletop setting would need to declare her intent to use it before I ever dropped a die. Not knowing I was about to drop a die complicates things here, so Dory can use it now but the outcome is uncertain.
Yes, the async part of how we do this does make it a little more complicated. But given how much Dory talks about using her shield to help her friends, and the fact that it is an immediate action that doesn’t affect anything else on her turn, I am comfortable making a general statement that Dory always intends to use Saving Shield against the first attack that targets an adjacent ally – just as we all assume that when Bonnie goes someplace, Dory will follow her, absent other orders.
The situation is a little different with Bodyguard, which provides the same AC bonus but consumes an AOO, so for that I definitely see the need to either pre-declare that she is using it or pause to ask before rolling the attack. And it’s cumbersome to ask every time but it’s also cumbersome to roll back completed attacks, so how would you like to handle it going forward?
Regarding the current attack against Coleman, if you are most comfortable re-rolling it so everything gets applied at the same time, that works for me. Dory can’t see the Hound that attacked, but knows Coleman is vulnerable in that doorway; she would have had her shield ready.
To me it seems like if Medio could target Hound 2 from his square, even at -4 due to their cover, Johnny might be in position to do the same, as his line of sight looks a lot better.
But we didn’t really get a detailed description of the cages in the room, though, which seems pretty important in deciding whether Johnny can thread a crossbow bolt through them and hit a target in the room beyond.
And shooting through the cages carries other risks too: Dory was concerned enough about the Grimlocks getting hurt to think about asking them to move back to the west before we opened the door, but doesn’t speak their language, so it didn’t happen.
