The “Your Blood Hound is freezing and drops to the bottom of the action queue.” effect in the Snow realm happens with very weird timing. They don’t seem to actually drop in the queue until someone takes an action. Most recently, I had this happen:
Combat began, and my Fallen Carnage was first (my team had Topaz Affinity). Before its turn, the message popped up “Your Fallen Carnage is freezing and drops to the bottom of the action queue.” Nevertheless, my Fallen Carnage’s turn popped up. I picked “Attack”, moved the selection cursor around on some enemies, and then canceled (I don’t remember why). Suddenly, it wasn’t my Fallen Carnage’s turn any more; the second creature on my team took a turn.
