_cosmo_: An "Invunerable Fruit" is sort of like a jewel. Invulnerable Fruits are VERY rare and only the really strong mobs drop them. If you eat one you will become invincible for ten minutes but it does not work in PvP. Just a random idea I wanted to share. Have a nice day!

dreamer: Invincible = overpowered
