Strengths and Weaknesses

This fruit's main strength is that it allows the user to gain much longer lifespan and also makes them age much slowly than normaly, as Ronusay himself is over three hundred years old and still looks around 20-30 years old.

Also it allows user to gain much greater knowledge of things, because user can explore and study things much longer and calmly with knowing they will live for secveral centuries. This allowes user to to master things from martial arts, navigation, swordsmanship and such.

Even though, user is not immortal and can be killed same way as everyone else (from bullet wound, sickness etc.) which acts as fruits main weakness.
