In the Naruto series, the curse mark is a form of transformation that enhances the power of the user. The multiplier for the curse mark can vary depending on the individual and their level of mastery over the form. In general, the curse mark can increase a user's physical abilities, such as strength, speed, and durability, by several times over their base state. The exact multiplier is not specified in the series, but it is generally considered to be a significant power boost.
