Notify Symon of the properties of the cloak and give it to him, cheerfully tapping him on the back.
"That's a fancy cloak you got there, Symon. When I form the cloak guild I was thinking about, I might even invite you to join."
Check for anything else in the wagons.
You don't seem to find anything else of interest. Perhaps its time you let someone else dig through.
Grot digs a little bit himself. He finds more socks and finds a rather ornate short sword that seemed to be entangled in a bunch of clothes and bundled up as if to hide it. Whoever put it here obviously tried to hide it. The bundle also has a bag similar to nadarr's bag attached to it. Grot opens it and finds it is the exact same kind of bag and pulls out a handfull of gems. There are eight gems total. He then shoves all of his socks into the bag and smiles gleefully. He also throws his old sword in there and takes his new one. He has no idea what it does though. ((How the hell did i roll really really really high on his check/percentile!?))
There is now less stuff in the one iwth odds and ends since Grot took a good chunk with his sock hoard. He doesn't even try to look for potions since he doesn't like stabby things.
Using Nimue to assist, look for anything that might have been missed. Don't go digging through broken glass unless something is spotted.
You go diving into the wagon and look about. You dig about and Nimue spots something; a rather special looking dagger. It also appears to be in the bundle that Grot found but he overlooked. You look at the potions (3+0) and see no other potions that you can grab right away. Nimue, however, spots a couple, but still a little buried, but enough that you won't get as hurt as dummy 1 and 2 who jumped right in.
