if NPCs needed to have a level advantage to win then a level 90 player would be able to beat a level 90 raid boss which isnt the case since it took 5 level 100 players to beat asura a boss who was level 90 i dont know how else i can put it

also theres nothing saying the NPCs were stupid in the game, they obviously were not as smart as humans but im sure the raid bosses and world bosses had extremely high A.I this is backed up by the fact that when shalltear was mind controlled she pretty much reverted to being a game NPC she couldnt think for herself and could only react like she would in the game (only attacking when she is attacked) yet her "A.I" was still high enough for her to use tactics to fight ainz like killing her summons to get health back
