Excelsior

I was just in Doom and everything was going fine until we got to Room 4 where the Dark Knight Samual spawns. We started killing him and he did his shadow jump thing but never reappeared. We could hear him and hear our pets making the same noises over and over like the sound was in a loop. We tried using reveal and detect hidden but neither worked. We couldn't leave the room because the door was still locked so we had to use the help option for being stuck to leave. So Samuel is glitched big time and needs to be fixed before anyone else can go through the rooms to summon the Dark Father.

probably just couldn't find him, it can be really difficult sometimes.

The thing about the shadow knight is that he will always hide and never come back until he reaches full health again (a long wait, when I couldn't find him once, it took approximately 40 minutes for him to re-appear).

If you using pets, use all kill instead of all guard, they will walk straight to his location (again don't do what I do sometimes and think he's dead and instantly say "all come") the "poof" from his shadow jump happens where he ends up not where he jumps from so that's a clue as to where he is, he will NOT move about any more than this.

ALSO: important to remember detect hidden / reveal only works on the exact tile he is standing on.

If done properly this battle can be over in seconds. Good luck and take care.

Also if you don't have detect hidden, don't forget some reagents for reveal >_<

Another tip to help find him is to attack him with a weapon that uses bleed attack as a special ability. A pool of blood will show up where is standing.
