Interesting, I didn't realize the AI was "don't charge the final step to you if you can instantly kill them". In practice, because there's no reason to attack a monster you don't intend to finish, it just means the clock spiders have unique AI which in some cases makes them more dangerous than the higher-health enemies.
I have something vaguely similar in my submission, where at a certain health threshold, enemies will stop stepping next to the player, and have a 50% chance of hopping backward instead of attacking.
