List of Skill upgrades in Puzzle & Dragons: Super Mario Bros. Edition
In Puzzle & Dragons: Super Mario Bros. Edition, players can increase their characters' Skill levels in the Skill Up spot at Toad Houses using Skill Items that can be obtained by opening ? Blocks, defeating enemies with 10 combos or more, or winning them from the Lucky ? Blocks spot. All characters' Skills start at level 1 and can be increased one level at a time until they reach the maximum level, level 7. Increasing a character's Skill level requires a certain amount of Skill Items which increase as their levels go up, and require rarer, "Grand" or "Rare" variants of Skill Items for later levels. Increasing a character's skill level by one reduces the required wait time for a character to use their Skill by one turn.
Awoken Skills can also be upgraded by using Star Gems to increase their levels.
