The group did not die fighting the Arixx, but it was only because of some very lucky rolls and the fact that in every instance where I could have been mean it would have meant killing the Fury first.  And I didn't want to kill that character, because the player is uncharacteristically focused in this game, and was the only one who suggested they rest.
Tactician player continues to not quite understand how Parry works, and gets annoyed that the "You can shift 1" doesn't let him completely mitigate the attack but the Conduit at least realized praying when you have 2 stamina, are bleeding, and already have a ton of Piety is a bad idea.
