Kingdom Hearts: Chain of Memories/Sleights

Riku's Sleights
Riku does not learn sleights through the same methods as Sora. Instead, every sleight he learns is given to him after leaving Hollow Bastion and talking to Ansem and The King. In Chain of Memories, these depend solely on Dark Mode and the The King Friend card, but in Re:Chain of Memories, the Duel system and its sleights are added to the game, allowing Riku to perform more sleights on his own.
