Character Bio:
Lucidien Kallister claims to be Goha #7's best Duelist - and he may have a point! With skills beyond those of a fifth grader, Luke is ready to blaze the highway to becoming the King of Duels.
He's super confident in any situation, except when it comes to his sister Tiger who's always quick to put him in his place. In a Duel, Luke's strategy is to focus on attacks - which isn't hard to do when he has Dragons as powerful as Multistrike Dragon Dragias!
Luke enters the tournament to become the King of Cross Duels. But there's just one problem - he can't find a tag partner! As he's wondering if he can be his own tag partner, he luckily meets the player to form a new team.
How to Unlock Luke:
Luke is unlocked by obtaining 1 Luke Character Piece.
You can obtain this by achieving 10 Cumulative Victory Points in Tag Duel (SEVENS).
Level Limit Increase:
Character Pieces, acquired by completing the Cumulative Reward track in Tag Duels can be used to increase a characters Trust Level limit.
At Trust Level 10, using a Character Piece will increase the Trust Level limit to 20.
At Trust Level 20, using a Character Piece will increase the Trust Level limit to the maximum of 30.
Note: Using a Character Piece to increase the Trust Level limit will stop you from earning Loop Rewards until you reach the new Trust Limit cap.
