The real advantages of the Samurai, though, are his weapon, the Great Katana, his Store TP ability that allows him to accumulate TP faster than other melee classes, and his Meditate ability, which will almost instantly give him 100% TP. TP is used to do Weapon skills. When weapon skills are done in a particular order, they will form a Skillchain and cause massive damage. Great Katanas are also notable in the game as being easy to make skillchains with, so the samurai can be a major force multiplier and a party player.
