King of Battle
Trophy Description - Achieved five-star ranks in all Coliseum Attack stages.

Trophy Type - Gold

There are 3 coliseum Attacks that you need to get a 5-star ranking on, each of them having 10 levels each. The enemies get progressively harder as you advance to the next levels. Rankings are based on how far youve made it through the stage. I always received 5-star ranks as long as I defeated the enemies in all 10 levels. I used Dark Knack since he has a high defense rating and was able to withstand a hit or two without dying. After increasing in size from Little to Big Knack, he was able to withstand even more hits. Of course if you have him unlocked, Diamond Knack is the obvious choice for these challenges. His attack power is maxed out and his health bar extends more than halfway across the screen. Regardless of which Knack you choose, be aggressive in your attacks. The faster you take enemies out the better. Also, concentrate on the most dangerous enemies first. Learn their patterns and how to effectively kill them. Double jump (X+X)and dash into enemies (RS+Square) when you have nowhere else to go but up. Finally, save a ring of sunstone power to destroy the powerful enemies in level 10.

Speed King
Trophy Description - Achieved five-star ranks in all Time Attack stages.

Trophy Type - Gold

There are 13 time attacks that you need to get a 5-star ranking on, one for each Chapter of the game. The challenges will become available once you complete the game for the first time. You can complete them using Basic Knack or any upgraded Knack character that you've unlocked by finding crystals. Rankings are based on the time it took you to complete the stage, how many enemies you killed, and whether or not you completed the stage without taking damage. I used Sunstone Knack to finish each stage since he automatically gathers sunstones without touching them and has more powerful sunstone attacks. I increased my score by executing sunstone attacks when the greatest number of enemies were surrounding me or at the most critical pinch points in the stage.
