Go for it and hope for the best.

You don't have time to think of anything else, and quickly cut through your own flesh with the dagger, enough to make for what you hope are believable claw marks and cause bleeding, but not so much that it depletes your health too much. Then you lie down on the cave floor face down, a little bit away from the wolves, and try to breathe as little as possible.

You hear the heroes come close enough to spot you, and then you hear their voices again.

"Oh... Looks like we're on the right track."

"I don't think so. Look. The cave ends here, and all I'm seeing is a few wolves."

"Do you think they're the ones that killed the noobs?"

"Seems more plausible to me than the werewolf story. Those idiots mistook wolves for werewolves in the dark and spread out stupid rumors."

"So we'll just leave, then?"

Yes, please do that, you think to yourself.

"Nah. I didn't walk all this way to go back empty-handed. We'll just kill the wolves and consider our mission accomplished. Dangit, I was really hoping for a werewolf fur... But whatever, a few wolf furs will have to do."

No... Ohhh no, you would not let that stand. Or would you? Wouldn't the wolves just respawn? But still, getting killed still hurt, you knew that. And they were your friends. But were they worth your very finite life?
