Deep Focus

Deep Focus is a badge in Paper Mario

This badge gives Mario extra star points when he uses the 'Focus' attack. This badge, however, does not work for partners who are using the effect of Group Focus. This badge costs only 1 BP. The badge gives Mario about double the Star Points he would normally obtain while using Focus. Since Paper Mario doesn't have Stylish commands, I would put this badge at a 4/5 stars rate. That means this is a pretty good badge to have. There are three Group Focus badges in Paper Mario. The first is at Princess Peach's caste. It is in the room with the large treasure chest. If Peach fails to give it to Mario via that chest, Mario will have to pick it up while he is there. The second Deep Focus is found in Shy Guy's Toy Box. Later on, on the way to get Watt, Mario can find a empty space in between two brick blocks on the ground level. By jumping in this space, Mario can reveal an invisible ? Block containing this badge. Be warned, however, there is a Pyro Guy waiting and Mario might accidently step on him. The third and final Deep Focus is found in Bowser's Castle. It is actually outside, however. After Mario shuts the lava flow down, he can walk on the molten floor. He can also access a secret pass into the lava moat of the castle. Since there is no more lava, Mario can walk all of the way to a mound by the door to the castle. It is here, Mario finds the Deep Focus badge in a ? Block.

Trivia

 * This badge is not in Paper Mario: The Thousand-Year Door as Super Appeal takes its place to furhter enhance the Play-like Setting the Paper Mario games have.
 * The Deep Focus badge in Bowser's Castle is actually glitched and shows the sprite of a different version of the badge. This different version was cut and most likely changed to Deep Focus. This also might support why this badge is found at Bowser's Castle, the last dungeon in the game.
