IT IS OVER
Okay, looking at Dave's post a little more carefully, I see that on the next round, he smacks Andicorn again for 12 hp or so. That'll do it.
The reign of the Unicorn King comes to an end.
Sure, maybe Cinder you hit or something this round, do the 5 it takes, but let's say you hit next round, Andicorn gets in one more good jab, right into Brogg's spleen for 8, taking him deep into negatives, -6 hp. Cinder, Dave, and Mike tag team the unicorn and bring him to his four wobbly knees. Cinder cuts off a back leg, and Dave hits Andicorn's lower jaw so hard it falls off of his face, and blood pours out from the top part of the now-jawless mouth of the unicorn.
Working fast, you guys bandage Brogg and Marivhon, and decide to camp here for the night. Here's the treasure: 10 unicorn horns, Romeo's steel-tipped horn, Andicorn's enormous golden lance of a horn, and Andicorn's jeweled crown. Should be worth a fortune.
A cool 1000 xp apiece for the victory y'all. This puts Cinder and Mike into the realm of 5th level, but remember, you can't train down here in the caves. Yeah, where the hell are you guys anyway? When you wake up, Dave, give me a new spell list for the day. Actually, let's just say you guys stay down here a couple nights to heal to full... you've got lots of fresh water and horse meat! So you're all at full, Brogg'll take a couple Lights and a Speak w/ Animals for some orientation if necessary.
Plan?
