Cameo fights are back in Tales of Innocence R.
They were missing in Tales of Xillia, making you wonder why? Isn’t it an anniversary game. Anyway, it’s not big issue, but cameo appearances were always cool in Tales games.
After getting through sky castle, Cameo battles can be fought in arena. I don’t think they will appear before it, but I could be wrong though.
Milla from Tales of Xillia can be fought in Arena, single mode.
Hisui and Kohak from Tales of Hearts in Arena, Party mode.
I have yet to beat any of them as it’s rather difficult, even on lower difficulty. Items are restricted, so no spectacle to scan stats as well…
