The last session I ran, yeenoghu sent some forces to invade a town and the party managed to defend with minimal casualties.
They all managed to defeat several gnolls, a couple of hezrou demons, barlguras, and Vrocks.
Enjoying how creative my players are becoming, the whole encounter ended with the barbarian/druid who had cast the jump spell and wild shaped into a bear and leaped across half the map to finish off the last demon. It was epic!!!
