Nah, from what I've been reading "acting intelligently" means that everything in the dungeon is an advanced telepathic hivemind that can straight up nosell any prep like watches setup by players and having players who don't even care about that kind of railroading enough to speak up.So what I've learned about this is that you should totally make illusory Tiny Huts to mess with enemies, because they automatically recognize one on the spot and have countermeasures prepared to deal with one.
Well, that's what I would do, if illusions didn't suck in 5e and there was one that could make an illusory object for longer than ten minutes...
I don't think that the hive mind would be subject to the illusion given it's omniscient perception capabilities
