Daeman walks confidantly toward the pair of irritable orcs holding a rather warm tankard of equestrian excretions. His mind a Storm with whirring thoughts.
"Equestrian exrement heh, thats good...hmmm... surely I can squeeze that into a song somehow"
"I wonder how much of that orcs expression is confusion, and how much is seething homicidal rage."
"I need a plan..."
"Wait!.... Why do these dwarves keep a ready supply of horse pee?"
And just before the orcs can approach to stop him Daeman finds inspiration.
Walking towards the orcs he raises the tankard "Hail friends I come bringing gifts and fair tidings fro...." and then he barges suddenly and erratically past the orcs and into their tent, making his charge appear to be an accidental stumble (bluff 25). As the two orcs follow him in (probably with the intent of doing something unpleasant) he whispers with impish importance.
"Hold there, I need your help to take those dwarves down a peg or two. All I need is a few moments of your time and the three of us can make a dwarf swallow a tankard of horse piss" He flicks a coin toward one of them. "Here is a silver piece just to hear me out."
Play by play: Assuming he doesn't get shived Daemans next move is to get one of the orcs to stand outside and make sure none of the dwarves try to eavesdrop. Then he pours the piss into one of his own canteens and casts presitidigitation (asking the remaining orc to make some noise to cover the sound of his verbal components) he uses the spell to clean the empty canteen and the pee he no doubt spilled and to chill the urine and change the smell coming from the canteen from that of pee to that of fine dwarven brandy. Daeman has spent his life around port taverns so hopefully he has a convincing memory to draw from. Next he casts silent image (the area encomapassing the tent and a ten foot cube outside of it in the direction of the dwarves) of a typical looking orc holding a tankard identical to the one the dwarves gave to Daeman.
Then he will walk back over to the dwarves (his magically pleasnt smelling piss canteen in tow) concentrating on his spell and making his orc illusion walk out displaying the tankard and a pleasant smile to the dwarves. [Daeman will explain his plan at length to the orc and got a 15 for a diplomacy check if one is needed.]
"Well friends I've got great news! At first yonder orcs refused to believe you had good intentions. But I talked to them and explained how badly you wanted to patch things up. They not only agreed to your token of amends but they offered thier own brew they said they purchased long ago and have been saving for a special occasion! (He holds out the canteen) Their leader wants to toast together to signal your fresh start. At this point Daemans orc illusion will raise his tankard signaling the dwarf to drink and begin to raise the tankard to his mouth. Hopefully with the dwarf following suit. (bluff 17)
Daeman will also be preparing to bolt since the piss only smells like fine brandy.
