"THAT WON'T BRING HIM BACK_" When it appears, move to another room. Failure to do so will have it move on to a different target. When encountering another enemy, look for any slight changes, something that looks out of place. If you do find it, do not take care of it as normal. If you remain ignorant, than it will not hesitate to move onto you.
