Celestial Symbol is a currency only obtained in the Celestial Zone. You must kill Itachi's to get your first Celestial Symbol. It's suggested that you only kill Itachi's until you obtain 2,000 Celestial Symbols. From this point you have enough Celestial Symbols to challenge Madara.
*When challenging Madara you'll be teleported into an instance. If you have a Mini-Me make sure to have it summoned before challenging! You'll also want at least 1 Divine Potion of Durability as for without one Madara Uchiha will One-Shot you!*
