As the great cat roars at it, the damage is massive, and the swarm splits into two!
(I assume you don’t drive it quite as far back so that Forge can still reach it through the difficult terrain).
Forge charges and hacks at one of the swarms…though again, his axe is less effective than the cats or Sim blasts and bursts.
Several of you realize that the debris is similar to the ruins you waded into before, inducing a mild panic, and granting combat advantage.
Standing next to the swarms also turns out to be painful (20 damage to Forge).
Then, a second (or is it third?) swarm emerges.
They all swarm the dwarf. One makes a devastating attack (crit) and knocks the dwarf prone into the battle remnants for more damage (another 72 dmg total).
Keep going.
