Isn't that when enemies hp goes to 1.5 hp and attack and defense doubled? If so still not too bad 2-3 broggie bounces for an enemy with 1500 hp and he's dead with that. Then 1 punch and inhale then to mario and Luigi. 1 magic mirror and 1 snack basket , dodge, 2 falling stars so long dark bowser! I can only imagine Bowser x with that much hp.
