Ok, let's see...
Kerith: You swing down and move behind the lizard (move equivelent), drawing your rapier and attacking it from a flanking position. You score, drawing forth a fresh gushing of dark blood. You must have hit an artery.
Norynth: With a dramatic flourish, you leap forward and slice the reptile in half. Both ends thrash for a moment, settling down to a steady tail-twitching as the beast dies.
Oren: The lizard is roughly man sized. You might be able to fit your head in its mouth if you tried really hard, but it would probably sufficate. You also notice that this is the same lizard Michelle blasted with her spell.
You glance around nervously, trying to see if there are any more opponents.
(Gertrude): The dog leaps forward, but stops and sniffs the lizard instead of biting the body. She looks at Norynth with a sort of annoyed glare and returns to his side.
Enemy: Before you even have a chance to settle down, another lizard drops from the loft, landing behind Kerith. It bites deeply, tearing at the exposed flesh of his neck. Kerith lets loose a burbling scream, then falls to the ground silent, blood pumping progressively more slowly from his wound.
(Titus): Seeing a new opponent roughly similar to the last, the dog remembers his orders and leaps to attack, biting the lizard in the front leg. She growls menacingly with her newly blood-stained teeth, showing she means business.
Grimbard: You charge forward, intending to send this lizard to follow its companion into the afterlife. Your dwarven axe scores a direct hit, cutting deeply into the shoulder of the giant lizard.
Michelle: You stand ready with your dagger, scanning the loft for more lizards, but seeing none.
Foran: You join Grimbard and attack with your sickle, making contact, but failing to penetrate the things thick scales.
I'd post the map, but at this point it won't matter too much, since you will find out quickly that this is the last lizard in the barn.
