Derp -facepalm-. Thanks >____>Why do you add 1? When you Sweet Scent Pokémon it says they have a monster frame of 2 but you never catch them on frame 3, do you?
The monster frame is the frame in which the Pokémon will appear if you do nothing but the action listed (sweet scenting, fishing). If you had to add 1 to the monster frame, you'd say most legends have a monster frame of 0 because they appear on frame 1 xD
It's a miracle I've caught so many RNG'd pokés thus far without understanding such basic knowledge.
