Luigi takes strenght and Iq in EVERY Round for strenght : Ghosts does not have a physical body so that mean they does not have a Weight/mass except when they focus to touch you + Luigi can lift and throw 60 million ton of castle as seen in Super Mario World (1990) by selecting him as the player when he beat the boss "Larry Koopa" but that's not all his strength feats. For the IQ: he's a doctor/scientist just like his brother + those ghosts didn't showed a lot of IQ feat especially King Boo . Anyway fire edit 🔥 😎
