Mario & Luigi: Partners in Time level up progressions

This page lists the stat increases earned from a level up and the required experience points needed to advance to the next level for Mario, Luigi, Baby Mario, and Baby Luigi in Mario & Luigi: Partners in Time. As with Mario & Luigi: Dream Team and Mario & Luigi: Paper Jam, the Bros. and their baby counterparts can level up to Level 100. Level 1 lists the initial stats for each brother, with the next levels listing the stat increases. The only stat that does not increase with each level up is STACHE; the player can only increase it with the bonus roulette. At the bottom of each chart lists the initial stats and the total amount of stat increases. Baby Mario and Baby Luigi require more EXP for a level up than their adult counterparts (up to 5,964 EXP each).
