Tried both for Rock Crabs, Barbarians, etc. It failed each time. For rock crabs, it would attack one that someone was attacking, it wouldn't attack one that was attacking me. At barbarians I had it set to only the level 17s in that building with the level 29. I go afk, come back it's just standing there not moving. I then set it to kill the level 29 too, I go afk for 10 minutes and my character is dead, not a big deal since I only lost like 6 lobs but still, with a cb level of 33 and a 45 str level I shouldn't be dying.
