I'm going to be honest with this guys. The 2nd boss is much harder than the first. (I don't want to give any names away.) You should prepare for him with good thunder spells and limit breaks filled.
Here's a tip, on easy it doesn't matter what perks you pick, on normal and machonist though, pick wisely! DOn't get 10% extra XP or more money, get GOOD perks!
Guys! Don't rate things down because someone wants to tell you their score, or tell someone else something! How would you like it if it happened to you?
Here's a tip, If you are fighting the enemy and just staying about 3/4 of the way and only Popo's spike is hitting the castle, DON'T QUIT, you gain XP by killing enemys! You will win eventually, just be patient!
