Proximity to the swarms remains a bad thing (20 damage vs Allowyn and Leandre, 10 vs Forge). As does more swarms, as another one animates.
The split swarm misses the cat (badly) then just hits it, until the Warlord calls out at just the right moment, annulling the attack and giving the cat a counter (you can roll). The attack of the new swarm is not annulled, and does hit, knocking the cat prone into the cursed bones and weapons, inflicting more damage (-41 HP).
Keep going.
