For those who play stealth characters with an unmodded Oblivion, I've been trying to recall if a certain Conjurer (conjurer dungeons) AI behavior is default/ comes with regular Oblivion.

The AI Behavior.
Does sneak attacking a lone Conjurer (away from any other enemies), without 1hit killing them, suddenly alert the rest of the Conjurers in that cell of the dungeon? Even though if the rest of the Conjurers are not in close proximity?
Was this Conjurer AI behavior perhaps added by KotN?
