Talk:The Dusk's Four Revisited (2016)/@comment-26970405-20160118083220/@comment-1465604-20160118181853

The rule of thumb is this:
 * If the base spirit you're evolving is a one-off item that dropped from quests or given as clear rewards, any Hidden Powers unlocked on the evo material carries over (Quan, I-Ling, Mumar & Pazza evolving to S-rank)
 * If the base-spirit is something you have to build through evolving a cannibal spirit, then Hidden Powers unlocked on the evo material do not carry over (Dogma / Wyvern to create Arlia / Bahamut, S-rank Mumar using another S-rank Mumar to evolve to SS (the same with Pazza)).
 * The one exception to this was the first day of Chocolat Forest Renewed, where the developers accidentally messed up the code, so that Hidden Powers on the base spirit did not carry over when evolving from S-rank to SS rank. They fixed this and gave out compensation.
