A guide on the best Rank-Up Bonuses to choose in Mario & Luigi: Brothership. Learn what each Rank-Up bonuses increase and the best bonus stats to pick when leveling up.

Best Rank-Up Bonuses

Best Rank-Up Bonuses for Mario

Rank Power	Rank Unlocked	Description
SPEED Up+	Koopa Shell (Level 8)	Increases SPEED value when leveling up by +1.
POW Up+	Boomerang (Level 15)	Increases POW value when leveling up by +1.
Hammerhead	Fire Flower (Level 22)	Increases damage dealt with Hammer attacks by 20%
Jump Man	Fire Flower (Level 22)	Increases damage dealt with Jump attacks by 20%
Bros. Pro	Superstar (Level 36)	Damage dealt by Bros. Attacks increases by 20%

Since Mario's stat growth favors his BP, POW, and Speed, we recommend that it is best to lean into his damage-dealer role by selecting the Rank-Up Bonuses that enhance his offenses.

Select the SPEED Up+ and POW Up+ Rank Bonuses early so that you can earn more points for these stats in the long run. It is much more effective to pick them early to make the most out of them.

The other selections here for Hammerhead, Jump Man, and Bros. Pro continue to buff his damage output, regardless of which method you prefer to deal damage.

Best Rank-Up Bonuses for Luigi

Rank Power	Rank Unlocked	Description
STACHE Up+	Koopa Shell (Level 8)	Increases STACHE value when leveling up by +1.
DEF Up+	Boomerang (Level 15)	Increases DEF value when leveling up by +1.
HP Up+	Koopa Shell (Level 8)	Increases HP value when leveling up by +1.
Big Lucky	Tanuki (Level 29)	Damage dealt by LUCKY attacks increases from 1.3x to 1.5x
Iron Body	Tanuki (Level 29)	Decreases damage received from enemies by 20%

On the other brother's hand, Luigi's stat growth favors his HP, DEF, and Stache. This makes him a suitable tank that is still able to deal the occasional wallop thanks to his Lucky hits. Capitalize on these strengths by choosing Rank-Up Bonuses that beef Luigi up more.

Picking up STACHE Up+ early, gives Luigi a safety net of a higher chance to deal Lucky hits later on to make up for his lower offenses. We recommend picking up DEF Up+ before HP Up+ by the simple fact that you can always regain HP with healing items, but there is no consistent way to increase defenses.

Big Lucky and Iron Body suit Luigi well, further emphasizing his defensive role of the duo.

Best Max Rank Bonuses

Rank Power	Rank Unlocked	Description
Casual Bros.	Superstar (Level 36)	Decreases BP used for Bros. Attacks by 30%
Gear Slot+1	Koopa Shell (Level 8)	Grants another slot for equipping gloves and accessories

At Level 43, you'll be allowed to grab two final additional Rank Bonuses. This can be a good chance for you to round out your build.

For your last two Rank-Up Bonuses, we recommend grabbing Casual Bros. to allow you to lean into a heavier Bros. Attack playstyle, and the Gear Slot to give you options for added bonuses that can be valuable in the endgame.
