Creatures of Aura

As the party explored the ancient tunnels, they stumbled upon a door that exuded biting cold. Opening it and entering the room, 2 wraiths were observed floating around and 2 zombies were stationed on either side of the far door. The zombies exuded an aura of extreme cold and the wraiths projected a sinister whisper.
Stepping forward, Mara launched a devastating barrage of arrows at one of the wraiths. Felling it in the first turn, she was ill prepared for the follow up attack of the second wraith. Before she knew it, she had been hit with a Touch of Madness and found herself swinging at Ekeraath. Fortunately, her basic attack was little match for Ekeraath's mountain of armor.
By the end of the round, the party had managed to fully enter the room and began setting up an offense against the creatures. The monsters held their own for a couple more rounds, but in the end, the party's offensive onslaught was far too much for them.
