Bosses can get status effects in Etrian Odyssey series. That's one of the best things about it. The bosses are super powerful too, so it doesn't break the game to be able to give them status effects. There's a lot of mid tier enemies in EO games that are strong enough to survive regular attacks for a few turns. Paralyzing or binding them often saves your party from taking damage.
That is great and is part of the mechanics, because it is kinda pointless to have 20 status and bosses being mute to all.
