>>38169982Level-up moves are: Growl (Level 1), Tackle (Level 1), Foresight (Level 6), Peck (Level 11), Hypnosis (Level 16), Reflect (Level 22; need to hold off on evolving it though), Take Down (Level 28), Confusion (Level 34), and Dream Eater (Level 48). As a Noctowl, it gets Reflect at 25, Take Down at 33, and Confusion at 41.
No, it doesn't get Light Screen, unfortunately. But Noctowl is pretty bulky on the special side. Hypnosis, Foresight (for Morty), Peck (for Bugsy and Sprout Tower), and Reflect are all worth it alone.
