Attempt an arcana check on the unknown corpses to see if they are something fey, shadow, elemental, etc. Use new power to help.
"Ugh. These poor souls were ripped to shreds. At least we avenged them, somewhat."
(?) You discover that they are natural origin.
Taste Bouchart's blood to check up on how tasty he is. Afterwards close his eyes if they weren't and loot his body. Stab the horse through the heart with the widow's knife and then taste the horse's blood.
Mumble quietly to himself
"Today was quite the feast. Better make sure I do this more often."
You taste the halfling's blood. It reminds you of back in Crimmor where these guys were plentiful. It tastes rather sweet for blood. You then go and kill his horse and gain total concealment. You taste the blood of his animal as it dies, and you remember you really never did like the taste of animal blood.
You gain all of bouchart's gear. (1 dagger, 1 hand crossbow, 209 gold, 2 healing potions, 50 crossbow bolts, a suit of small leather armor, and his hunter's flint)
You swear also, as you loot his body, you hear hisses and clicks in a distance, but as you look for the source, you find nothing
((As requested, if Lay on Hands will also fix my horse's legs, Karl does so. If not, he'll kill it cleanly.))
Karl gets to his feet with a groan and spits bear blood out of his mouth."Well, aren't we going to smell wonderful in a few hours?" he says as he bends to check on his faithful mount.
Your mount's legs are heavily wounded to the point more then just magic can help it, and even then, there is no guarantee that it will be able to walk after the horse's legs are fixed. (several nature/heal checks required)
