Kyouka's (Fairy Tail) curse "Strengthen" can increase her own power exponentially.
Summary
The user can empower their physical power and/or existing abilities to higher levels, in some cases certain users can even augment their powers to their highest/absolute level. These boots are usually temporary and are specific to one or a number of statistics. Statistical Amplification should not be confused with a change of form or state and is therefore not usually associated with new capabilities in particular.
