In MapleStory, Inner Ability unlocks at level 50 and allows you to rank up from Rare to Legendary similar to cubing. Unlike cubes, however, you may tier down (Epic -> Rare) if you don’t lock your rank or use a Circulator. You can reset your Inner Ability using Honor Points, which can be acquired through regular gameplay (bosses, events, quests, etc).

Optimal Inner Ability

The chart below shows the recommendations for each class. Some lines have multiple options that are separated by a backslash and it’s up to you to decide depending on what you’re lacking in terms of progression. If the text is bold, it’s slightly better than others. You cannot have the same Inner Ability on another line (ex: First line: 20% Boss Damage, Second line: 10% Boss Damage).
