Be the bait.

You tell amethyst to sneak up on the boar as you will direct it attention to yourself. She simple nods at you and vanishes into the shadows of the trees. You scream as loud as you can trying to draw the boars attention, and it works. With in seconds the boar See's you as more of a threat then the dwarf, and tries to turn to charge at you but only stumbles over it own it momentum. This causes the boar to fall over onto it side. Then as quick as lighting amethyst drops from the trees while the boar in **** and stick her dagger straight into it neck, killing it instantly. The dwarf looks relieved and thanks you. Apon closer inspection you find that the reason this dwarf is in rags is because he was a ****. You could easily tell by the magic collar around his neck. He was most likely ordered to stay behind and get killed by that boar so his master could escape. Which was a very common thing to do. Sadly for you because he was a **** means he couldn't give you anything in return for saving his life, even if he wanted to. Most slaves held no possession or finances unless their master allowed it which was incredibly rare. Your best bet would be to return the **** to his rightful owner and hope for a reward, but would be most unlikely. Or since you have experience with these collars you could easily remove it.
