The others looked at Eisen with rather confused expressions, while the old man himself simply took deep breaths while trying to supress his urge to scream out in pain, because this hurt him an incredible amount. It was a smooth, quick cut, so it probably wasn't as bad as it could have been, but it was still very, very bad.
For now, the old man just drank a health potion and had the wound close up and have his health recover to the top again. The finger didn't grow back, but it would do that once Eisen just went to sleep.
