But even as they do, there is a fierce roar that erupts from behind the door ~ there is something big there, something unfamiliar. Even Engelhart's beast knowledge cannot identify the creature that made such a roar ~ but then, much of his knowledge is from lectures and books, lacking a certain amount of auditory or perceptive confirmation. It sounds like a beast to the cleric.
The four creatures, as I said, turn on the party:
The one creature that was partly hurt slashes at Embla with one claw, hitting AC 3. It causes 2 damage.
Lothar gains +1 AC from the chest, which is between him and the frog humanoid that attacks out of 1010 ~ but it is no matter. It goes low for Lothar's legs with its horn, miscalculates and snags the corner of the chest, rolling a natural 1. This unbalances it and the creature loses its claw attacks for the round.
Finally, the last creature horns Pandred, hitting AC 2. Pandred takes 4 damage (does it stun?). The creature attacks with both its claws, but Pandred manages to fend those off with her shield.
